Abstract

A human body physiological signal collecting device (10) and a human body physiological signal collecting system. The human body physiological signal collecting device (10) comprises a flexible pad body (11) having a coarse surface, a piezoelectric thin-film sensor (12), a signal collecting processor (17), and a signal output interface (16). The flexible pad body (11) is provided with an interlayer. The piezoelectric thin-film sensor (12) is provided in the interlayer. The piezoelectric thin-film sensor (12) is connected to a signal collecting processor (17). The signal collecting processor (17) is connected to the signal output interface (16). The piezoelectric thin-film sensor (12) distends downward when pressed and generates a pull with parts outside of the point to which force is applied. Because of the self-locking action between coarse surfaces, the flexible pad body (11) has a slip-resistance effect, and a repeated pressure of small amplitude becomes a corresponding pulling force, thus an electric signal corresponding thereto is generated by the piezoelectric thin-film sensor (12), the electric signal is collected by the signal collecting processor (17) and processed into a human body physiological signal, and the human body physiological signal is outputted by the signal output interface (16). The human body physiological signal collecting system comprises a smart terminal (20) communicatively connected to the human body physiological signal collecting device (10).

本发明的有益效果为：区别于现有技术的使用表面光滑的塑料包裹压电薄膜传感器的装置，在使用的过程中需要通过双面胶与床垫粘结，才可以采集到显著的拉力变化，如果不与床垫粘结，就会产生滑动，而不会采集到小幅度重复的 拉力变化，从而失去采集人体生理信号的准确度，而本发明通过表面粗糙且带有夹层的柔性垫体和设置于夹层内的压电薄膜传感器形成一个人体生理信号采集装置及其***，将柔性垫体设置在沙发、床垫等软性物体上时，当物体压迫在柔性垫体上时，柔性垫体的受力点会发生拉伸形变，从而使夹层内的压电薄膜传感器采集到拉力变化，但是如果柔性垫体与沙发等软性物体之间无摩擦或摩擦小，导致柔性垫体相对于沙发等软性物***移较大，且不会产生重复的拉伸，使得压电薄膜传感器采集到无用的拉力变化，而本发明中的柔性垫体使用粗糙的表面，当物体压在柔性垫体上的时候，压在柔性垫体上会与床垫产生较大的摩擦力，产生“自锁”效果，使得压电薄膜传感器可以采集到小幅度重复拉伸的力，从而可以准确的采集到人体生理信号的变化，而且在使用时直接铺在床垫或沙发等软性物体上即可，使得人体生理信号采集装置方便移动，重复使用不受限制，使用率更高；人体压在人体生理信号采集装置上方的被单时，人体生理信号采集装置被压迫向下变形，与受压点之外的部分产生拉扯，由于压电薄膜传感器与床单和床垫之间的自锁效应，夹在被单与床垫间的受力点之外的部分有阻止位移的趋势，对于轻微变化的压力，会产生与之相应变化的拉力，从而使得压电薄膜传感器产生相应的电信号，然后经过信号采集处理器采集处理为人体生理信号，人体生理信号由信号输出接口输出只智能终端，智能终端分析得到人体相关的生理数据，如呼吸、心跳等生理数据，结构更加的简单，无需进行植入杠杆等复杂结构；同时发明中的柔性垫体中设置的压电薄膜传感器可以更薄，从而提高用户的体验，压在柔性垫体上更加的舒服。The invention has the beneficial effects that the device for using the plastic-wrapped piezoelectric film sensor with smooth surface is different from the prior art, and the double-sided adhesive is required to be bonded to the mattress during the use process, so that significant tensile force changes can be collected. If it is not bonded to the mattress, it will slip, and will not collect a small amount of repetition. The pulling force changes, thereby losing the accuracy of collecting physiological signals of the human body, and the present invention forms a human physiological signal collecting device and a system thereof by a rough surface and a flexible pad body with a sandwich layer and a piezoelectric film sensor disposed in the interlayer, which will be flexible When the pad body is disposed on a soft object such as a sofa or a mattress, when the object is pressed against the flexible pad body, the force point of the flexible pad body is stretched and deformed, so that the piezoelectric film sensor in the interlayer collects the pulling force. Change, but if there is no friction or friction between the flexible pad and a soft object such as a sofa, the flexible pad body is displaced relatively much with respect to a soft object such as a sofa, and does not cause repeated stretching, so that the piezoelectric film sensor Unusable tension changes are collected, and the flexible pad body of the present invention uses a rough surface. When the object is pressed against the flexible pad body, pressing on the flexible pad body will generate a large frictional force with the mattress, resulting in " The self-locking effect enables the piezoelectric film sensor to collect a small amount of repeated stretching force, so that the physiological signal of the human body can be accurately collected, and When used, it can be directly placed on a soft object such as a mattress or a sofa, so that the human physiological signal collecting device is convenient to move, the use is not restricted, and the usage rate is higher; when the human body presses the sheet above the physiological signal collecting device of the human body, The human physiological signal acquisition device is pressed downward to be deformed downward, and the part other than the pressure point is pulled. Due to the self-locking effect between the piezoelectric film sensor and the bed sheet and the mattress, the force point between the sheet and the mattress is clamped. The outer part has a tendency to prevent displacement. For a slightly varying pressure, a correspondingly varying pulling force is generated, so that the piezoelectric film sensor generates a corresponding electrical signal, and then is collected and processed by the signal acquisition processor as a human physiological signal. The human physiological signal is outputted from the signal output interface only to the intelligent terminal. The intelligent terminal analyzes and obtains the physiological data related to the human body, such as physiological data such as breathing and heartbeat, and the structure is more simple, and no complicated structure such as implanting a lever is needed; and the flexible pad in the invention The piezoelectric film sensor provided in the body can be thinner, thereby improving the user experience and pressing on More comfortable on the mat of the body.
