Description

Wearable device

Technical Field

The present disclosure relates to wearable devices, and more particularly, to a wearable device using a piezoelectric-actuated pneumatic actuator to sense physiological information.

Background

In the modern society, which demands for rapidness and increasingly large personal pressure, people are developing to monitor or inspect their health frequently in the course of increasing their consciousness for pursuing personal health. Generally, the conventional data measurement for human physiological health information mainly uses a fixed sphygmomanometer or a bulky detection apparatus, which usually includes components such as a motor-type gas pump, an air bag, a sensor, an air release valve, a battery … …, wherein the motor-type gas pump is prone to generate friction loss, and the components are bulky after being assembled, which is not favorable for frequent use, but if a motor-type gas pump with a smaller volume is adopted, the loss speed is faster and more energy is consumed.

In order to facilitate regular monitoring of health conditions of a general person and to make the monitoring device portable, wearable health monitoring devices are increasingly available. However, in the conventional wearable health monitoring devices in the market, the detection is usually performed in an optical detection manner, but the accuracy of the optical detection manner is not high, so that an error value is often generated, and reliable data cannot be effectively obtained.

generally speaking, to sense physiological information of a person to be measured, as shown in fig. 1, positions such as a head 1a, a heart portion 1b, a wrist 1c, or an ankle 1d are selected for monitoring, which are the positions in a human body where information such as pulse, blood pressure, and heart beat is most likely to be sensed, so that the physiological health information of the person to be measured can be quickly and effectively known through sensing at the positions. However, as mentioned above, if the wearable health monitoring device is used for optical detection, it is difficult to collect and report the detected data because of its low accuracy, but if the sphygmomanometer or other measuring instruments with high reliability are used in the aforesaid general workshop, the size of the instruments is too large to achieve the goal of being light, thin and portable.

Therefore, how to develop a wearable device that can improve the above-mentioned shortcomings of the known technologies and achieve the purposes of small size, miniaturization, portability, power saving and high accuracy of the personal health monitoring device is a problem that needs to be solved urgently.

Disclosure of Invention

The main objective of the present disclosure is to provide a wearable device using a piezoelectric-actuated gas actuator to sense physiological information, wherein the piezoelectric-actuated gas actuator transmits gas to an airbag to inflate the airbag, and then the sensor disposed at a relative position senses the physiological information of a wearing user, so as to solve the disadvantages of a detecting instrument in the prior art, such as large volume, difficulty in thinning, incapability of achieving portable purpose, low power consumption, and the like, and further solve the problem of low accuracy of an optical-detection health monitoring device in another prior art.

To achieve the above object, a broad aspect of the present invention provides a wearable device, comprising: the monitoring body comprises a main body frame groove, an outer frame of the main body frame groove is at least provided with a gas communication hole, and a protective film is covered in the gas communication hole to form sealing, water proofing and dust proofing in the main body frame groove; a gas actuator, which is arranged in the main body frame groove of the monitoring body and leads gas to the main body frame groove through the gas communication hole to be transmitted by the gas actuator in a centralized way; the gas actuator drives the operation transmission gas to be concentrated in the gas bag, so that the gas bag is inflated and expanded outside the monitoring body; the driving control module is arranged in the main body frame groove of the monitoring body and controls the driving operation of the gas actuator; and a sensor, set up in this main part frame groove of this monitoring body, through the control of this drive control module, and direct sensing this gas actuator drive operation transmission atmospheric pressure changes and calculates the physiological information of wearing the user.

And the micro valve device 22B is formed by stacking and assembling a gas collecting plate 226, a valve plate 227 and an outlet plate 228 in sequence, but not limited thereto. In the present embodiment, as shown in fig. 4A, the gas collecting plate 226 is not only a single plate structure, but also a frame structure with a side wall at the periphery, and the side wall formed by the periphery and the plate at the bottom thereof define a gas collecting chamber 226a, so that when the micro pneumatic power device 22 is assembled, the front schematic view thereof is shown in fig. 3, and it can be seen that the micro gas transmission device 22A is accommodated in the gas collecting chamber 226a of the gas collecting plate 226, and is stacked with the valve plate 227 and the outlet plate 228 below. The assembled back view shows the pressure relief through holes 228a and the outlet 229 of the outlet plate 228, the outlet 229 being adapted to be connected to the air bag 23, the pressure relief through holes 228a being adapted to allow the venting of air from the microvalve device 22B for pressure relief. By the assembly of the micro gas transmission device 22A and the micro valve device 22B, gas is introduced from at least one gas inlet hole 221a on the gas inlet plate 221 of the micro gas transmission device 22A, and is continuously transmitted through the pressure chambers by the actuation of the piezoelectric actuator 223, so that the gas can flow in one direction in the micro valve device 22B, and the pressure is accumulated in the gas bag 23 connected to the outlet 229 of the micro valve device 22B, and when pressure relief is required, the output of the micro gas transmission device 22A is regulated and controlled, so that the gas is discharged through the pressure relief through hole 228a on the outlet plate 228 of the micro valve device 22B, and pressure relief is performed.

Referring to fig. 4A and 4B, the air inlet plate 221 of the micro gas transmission device 22A has an air inlet hole 221a, a bus hole 221B and a bus chamber 221c formed integrally, and the bus chamber 221c is used for temporarily storing air, in this embodiment, the number of the air inlet holes 221a is 4, but not limited thereto, and the air inlet holes 221a penetrate through the air inlet plate 221, and are mainly used for making air flow from the outside of the device into the micro gas transmission device 22A from the air inlet hole 221a under the action of atmospheric pressure, the bus hole 221B is used for communicating with the air inlet hole 221a, the center communication position of the bus hole 221B is the bus chamber 221c, and the bus chamber 221c is communicated with the bus hole 221B, so that the air entering the bus hole 221B from the air inlet hole 221a can be guided and collected to the bus chamber 221c for transmission.

The resonator plate 222 is made of a flexible material, but not limited thereto, and the resonator plate 222 has a hollow hole 222a corresponding to the collecting chamber 221c of the gas inlet plate 221 for gas to flow through.

The piezoelectric actuator 223 includes a suspension plate 223a, a frame 223b, at least one support 223c and a piezoelectric element 223d, wherein the piezoelectric element 223d is attached to the suspension plate 223a for applying a voltage to generate a deformation to drive the suspension plate 223a to vibrate in a bending manner, the at least one support 223c is connected between the suspension plate 223a and the frame 223b for providing an elastic support, and at least one gap 223e is further provided between the at least one support 223c, the suspension plate 223a and the frame 223b for allowing a gas to flow therethrough. The outer frame 223b is disposed around the suspension plate 223 a. The piezoelectric actuator 223 is a concave piezoelectric actuator, in this embodiment, the suspension plate 223a and the outer frame 223b form a non-coplanar structure, the surface of the suspension plate 223a is lower than the upper surface of the outer frame 223b, and the surface of the suspension plate 223a is also lower than the lower surface of the outer frame 223b, so that the piezoelectric actuator 223 has a central concave disk-shaped structure; in addition, a space of the buffer chamber 220 is maintained between the surface of the suspension plate 223a and the resonance plate 222, and the space of the buffer chamber 220 can be adjusted by at least one support 223c formed between the suspension plate 223a and the outer frame 223 b. In this embodiment, the surface of the suspension plate 223a may also have a convex portion 223f, and the top surface of the convex portion 223f and the surface of the outer frame 223b are non-coplanar, in this embodiment, the top surface of the convex portion 223f on the suspension plate 223a is lower than the upper surface of the outer frame 223b, so that a space between the convex portion top surface and the resonant sheet 222 is formed, and the space between the temporary storage chambers 220 can be adjusted by at least one bracket 223 c. The gap between the temporary storage chambers 220 will affect the transferring effect of the micro gas transferring device 22A, so it is important to maintain a constant gap between the temporary storage chambers 220 to provide a stable transferring efficiency of the micro gas transferring device 22A.

The suspension plate 223a of the piezoelectric actuator 223 is depressed downward by pressing, so that the suspension plate 223a of the piezoelectric actuator 223 is depressed to form a space to form an adjustable interval with the resonant plate 222 for the temporary storage chamber 220. Through the structural improvement that the suspension plate 223a of the piezoelectric actuator 223 is formed with a recess to form a temporary storage chamber 220, the required distance between the temporary storage chambers 220 can be completed by adjusting the recess distance formed by the suspension plate 223a of the piezoelectric actuator 223, thereby effectively simplifying the structural design for adjusting the distance between the temporary storage chambers 220, and achieving the advantages of simplifying the manufacturing process, shortening the manufacturing time, and the like.

In addition, as shown in fig. 4A and fig. 4B, the insulating sheet 224A, the conducting sheet 225 and the insulating sheet 224B are disposed under the piezoelectric actuator 223 in sequence, and the shape of the insulating sheet corresponds to the shape of the outer frame 223B of the piezoelectric actuator 223. In some embodiments, the insulating sheets 224a and 224b are made of an insulating material, such as: plastic, but not limited to, for insulation; in other embodiments, the conductive sheet 225 is made of a conductive material, such as: the metal is not limited to this, and is used for electrical conduction.

Referring to fig. 4B, after the air inlet plate 221, the resonator plate 222 and the piezoelectric actuator 223 are assembled in sequence, the hollow hole 222a of the resonator plate 222 is located below the collecting chamber 221c of the air inlet plate 221, and a temporary storage chamber 220 is further formed between the resonator plate 222 and the piezoelectric actuator 223 for temporarily storing the air, and the temporary storage chamber 220 is communicated with the collecting chamber 221c of the air inlet plate 221 through the hollow hole 222a of the resonator plate 222, and two sides of the temporary storage chamber 220 can be communicated with the air collecting plate 226 of the microvalve device 22B through a gap 223e between at least one support 223c of the piezoelectric actuator 223.

Referring to fig. 5A to 5C, when the micro gas transmission device 22A is activated, the piezoelectric actuator 223 is activated by applying a voltage, and the suspension plate 223a is driven to perform a reciprocating vibration in a vertical direction with the support 223C as a fulcrum. As shown in fig. 5A, when the piezoelectric actuator 223 is actuated to vibrate downwards by applying a voltage, the resonance piece 222 also vibrates vertically in a reciprocating manner along with the resonance, that is, the portion of the resonance piece 222 corresponding to the bus chamber 221c of the air inlet plate 221 also deforms along with the bending vibration, that is, the portion of the resonance piece 222 corresponding to the bus chamber 221c of the air inlet plate 221 is regarded as the movable portion 222b of the resonance piece 222, so that when the piezoelectric actuator 223 vibrates downwards in a bending manner, the movable portion 222b of the resonance piece 222 is brought in and pushed by the fluid and the piezoelectric actuator 223 vibrates, and along with the bending vibration deformation of the piezoelectric actuator 223 downwards, the gas enters from at least one air inlet hole 221a on the air inlet plate 221, passes through the bus hole 221b to be collected to the bus chamber 221c at the center thereof, and then flows downwards into the temporary storage chamber 220 through the hollow hole 222a of the resonance piece 222 corresponding to the bus chamber 221c, thereafter, the resonant piece 222 is driven by the vibration of the piezoelectric actuator 223 to perform a vertical reciprocating vibration in accordance with the resonance. As shown in fig. 5B, the piezoelectric actuator 223 is lifted upwards, and the movable portion 222B of the resonator plate 222 abuts against the convex portion 223f of the piezoelectric actuator 223 that is displaced upwards, so that the temporary storage chamber 220 between the region outside the convex portion 223f and the fixing portions 222c at two sides of the resonator plate 222 is reduced, and the deformation of the resonator plate 222 compresses the volume of the temporary storage chamber 220, closes the middle flowing space of the temporary storage chamber 220, and causes the gas therein to flow towards two sides, and further passes through the gap 223e between at least one of the supports 223c of the piezoelectric actuator 223 and flows downwards. As shown in fig. 5C, the resonance plate 222 resonates upward due to the upward vibration of the piezoelectric actuator 223, and the movable portion 222b of the resonance plate 222 also moves upward, so that the gas in the confluence chamber 221C flows into the temporary storage chamber 220 through the hollow hole 222A of the resonance plate 222, and flows downward through the gap 223e between the supports 223C of the piezoelectric actuator 223 and flows out of the micro gas delivery device 22A. By repeating the above steps, the gas can be continuously fed from the inlet hole 221a and then delivered downwards, so as to achieve the purpose of gas transmission.

As shown in fig. 4A and fig. 4B, the micro gas transmission device 22A is formed by sequentially stacking a gas collecting plate 226, a valve plate 227, and an outlet plate 228. The gas collecting plate 226 has a recess to form a gas collecting chamber 226a, and the gas collecting plate 226 has a first through hole 226b and a second through hole 226c, one end of the first through hole 226b and the second through hole 226c are connected to the gas collecting chamber 226a, and the other end is connected to the first pressure relief chamber 226d and the first outlet chamber 226e of the gas collecting plate 226, respectively, and a convex structure 226f is further added at the first outlet chamber 226e, for example, a cylindrical structure, but not limited thereto.

The outlet plate 228 includes a pressure relief through hole 228a and an outlet through hole 228b, wherein the pressure relief through hole 228a and the outlet through hole 228b penetrate the outlet plate 228, the outlet plate 228 has a second pressure relief chamber 228D and a second outlet chamber 228e recessed therein, the pressure relief through hole 228a is disposed in a central portion of the second pressure relief chamber 228D, and a communication flow passage 228c is further disposed between the second pressure relief chamber 228D and the second outlet chamber 228e for gas communication, and one end of the outlet through hole 228b is communicated with the second outlet chamber 228e, and the other end is communicated with the outlet 229, in this embodiment, the outlet 229 is connected with the air bag 23 (or communicated with the inlet 231 of the air bag 23 as shown in fig. 2D).

The valve plate 227 has a valve hole 227a, when the valve plate 227 is positioned and assembled between the gas collecting plate 226 and the outlet plate 228, the pressure relief through hole 228a of the outlet plate 228 corresponds to the first through hole 226b of the gas collection plate 226, the second pressure relief chamber 228d corresponds to the first pressure relief chamber 226d of the gas collection plate 226, the second outlet chamber 228e corresponds to the first outlet chamber 226e of the gas collector 226, the valve plate 227 is disposed between the air collecting plate 226 and the outlet plate 228, and blocks the first pressure-relief chamber 226d from communicating with the second pressure-relief chamber 228d, and the valve hole 227a of the valve plate 227 is disposed between the second through hole 226c and the outlet through hole 228b, the valve hole 227a is disposed corresponding to the protrusion 226f of the first outlet chamber 226e of the air collecting plate 226, so that the air can flow in one direction due to the pressure difference by virtue of the design of the single valve hole 227 a.

A protruding structure 228f, such as but not limited to a cylindrical structure, may be further added to one end of the pressure relief through hole 228a of the outlet plate 228 to enhance the valve plate 227 to quickly abut against and close the pressure relief through hole 228a, and achieve a complete sealing effect due to a pre-stressing interference; the outlet plate 228 further has at least one limiting structure 228g, and in this embodiment, the limiting structure 228g is disposed in the second pressure relief chamber 228d and is an annular block structure, but not limited thereto, and is mainly used for assisting in supporting the valve plate 227 when the microvalve device 22B performs pressure-collecting operation, so as to prevent the valve plate 227 from collapsing and enable the valve plate 227 to open or close more rapidly.

When the microvalve device 22B is pressure-collecting actuated, as shown mainly in fig. 5A to 5C, which may be responsive to the pressure provided by the downwardly delivered gas from the micro gas delivery device 22A, or when the external atmospheric pressure is greater than the internal pressure of the bladder 23 connected to the outlet 229, the gas flows from the gas collection chamber 226a of the gas collection plate 226 of the micro gas delivery device 22A through the first through hole 226b and the second through hole 226c and flows down into the first pressure relief chamber 226d and the first outlet chamber 226e, at this time, the downward gas pressure causes the flexible valve plate 227 to flex downwardly and thereby increase the volume of the first pressure relief chamber 226d, and the end corresponding to the first through hole 226b is flatly attached and pressed against the pressure relief through hole 228a, thereby closing the pressure relief through hole 228a of the outlet plate 228 so that gas in the second pressure relief chamber 228d does not flow out through the pressure relief through hole 228 a. In this embodiment, a protrusion 228f may be added to the end of the pressure relief through hole 228a to enhance the valve plate 227 to rapidly abut against and seal the pressure relief through hole 228a, so as to achieve a completely sealed effect due to the pre-stressed abutting effect, and a limiting structure 228g may be disposed around the pressure relief through hole 228a to assist in supporting the valve plate 227 without collapsing. On the other hand, since the gas flows downward into the first outlet chamber 226e from the second through hole 226c and the valve plate 227 corresponding to the first outlet chamber 226e is also bent downward, the corresponding valve hole 227a is opened downward, the gas can flow from the first outlet chamber 226e into the second outlet chamber 228e through the valve hole 227a and flow from the outlet through hole 228b to the outlet 229 and the airbag 23 connected to the outlet 229, thereby performing a pressure-collecting operation on the airbag 23.

Referring to fig. 5D, when the micro valve device 22B is releasing the pressure, the gas transmission amount of the micro gas transmission device 22A is controlled to stop the gas from being input into the gas collecting chamber 226a, or when the pressure inside the airbag 23 connected to the outlet 229 is higher than the atmospheric pressure outside, the micro valve device 22B is releasing the pressure. At this time, the gas is input into the second outlet chamber 228e from the outlet through hole 228b connected to the outlet 229, so that the volume of the second outlet chamber 228e expands, and the flexible valve plate 227 is further caused to bend upwards and deform, and is flatly attached upwards and abutted against the gas collecting plate 226, so that the valve hole 227a of the valve plate 227 is closed by abutting against the gas collecting plate 226. In this embodiment, a convex structure 226f is additionally provided to the first outlet chamber 226e, so that the flexible valve plate 227 is bent upwards to change shape and to be quickly abutted, and the valve hole 227a is more easily closed by completely adhering and sealing with a pre-force abutting effect, therefore, when the valve hole 227a of the valve plate 227 is in an initial state, the valve hole 227a is closed by abutting against the convex structure 226f, and the gas in the second outlet chamber 228e will not flow back to the first outlet chamber 226e, so as to achieve a better effect of preventing gas leakage. And, the gas in the second outlet chamber 228e can flow into the second pressure relief chamber 228d through the communication flow passage 228c, so as to expand the volume of the second pressure relief chamber 228d and make the valve plate 227 corresponding to the second pressure relief chamber 228d also bend upwards and deform, at this time, since the valve plate 227 is not pressed against and closed on the end of the pressure relief through hole 228a, the pressure relief through hole 228a is in an open state, i.e., the gas in the second pressure relief chamber 228d can flow outwards from the pressure relief through hole 228a for pressure relief operation. In this embodiment, the flexible valve plate 227 can be quickly changed in the upward bending shape by the protrusion 228f additionally provided at the end of the pressure relief through hole 228a or by the stopper 228g provided in the second pressure relief chamber 228d, and thus the pressure relief through hole 228a can be more easily removed from the closed state. Thus, the gas in the air bag 23 connected to the outlet 229 can be discharged to reduce the pressure by the one-way pressure relief operation, or the pressure can be completely discharged to complete the pressure relief operation.

In summary, the wearable device provided by the present disclosure mainly controls and drives the piezoelectric gas actuator through the driving control module, so that the gas actuator transmits gas to the airbag, and the airbag inflates and expands to press a specific position worn by a wearing user, and then the sensor senses physiological information of the wearing user, thereby achieving an accurate measurement effect. Therefore, the wearable device adopting the piezoelectric-actuated gas actuator has great industrial application value and is applied by the method.
