as shown in fig. 2 and fig. 3, fig. 2 is a first structural schematic diagram of a flexible self-power-generating device provided by an embodiment of the present invention, and fig. 3 is a second structural schematic diagram of a flexible self-power-generating device provided by an embodiment of the present invention, where the flexible self-power-generating device 2 includes a positive electrode layer 21, a negative electrode layer 22, and an electrolyte layer 23 located between the positive electrode layer 21 and the negative electrode layer 22; the positive electrode layer 21 is a first liquid metal layer doped with first metal powder; the negative electrode layer 22 is a second liquid metal layer doped with second metal powder; the electrolyte in the electrolyte layer 23 is activated when it comes into contact with urine; the liquid metal (i.e., the low-melting-point metal) in the positive electrode layer 21 and the liquid metal in the negative electrode layer 22 both have a melting point lower than the normal body temperature.
After this intelligence panty-shape diapers's wearer urinated wet, the electrolyte in the electrolyte layer 21 contacts the urine, and then is activated for the galvanic cell reaction can take place for first metal powder in the positive electrode layer 21 and the second metal powder in the negative pole layer 22, and then makes and form the potential difference between positive electrode layer 21 and the negative pole layer 22, and then to 3 output current of alarm device, drive alarm device 3 works, remind nursing staff to change panty-shape diapers, guarantee infant and patient's health. In addition, the flexible self-generating device 2 has flexibility and a self-generating function, so that the energy consumption is reduced, and the comfort degree of a wearer is improved.
For the convenience of understanding and implementation of those skilled in the art, the following embodiments of the present invention will describe the diaper body 1, the flexible self-power-generating device 2, the alarm device 3, and the manner in which the alarm device 3 is electrically connected to the flexible self-power-generating device 2 in detail.
Optionally, the diaper body 1 comprises a surface coating layer, an absorption core layer and a base fabric, the surface coating layer and the base fabric are made of non-woven fabrics, and the absorption core layer comprises fluff pulp and super absorbent resin; wherein the surface covering contacts the skin of the wearer. When panty-shape diapers body 1 has above-mentioned structure, can place flexibility from power generation facility 2 inside the absorption sandwich layer, preferably crotch portion to make the electrolyte in the electrolyte layer 23 among the flexibility from power generation facility 2 can contact the urine better, can place alarm device 3 in the backer outside, preferably waist, so that wearer's experience is better, and the nursing staff is easier to observe.
Alternatively, the "flexible self-generating device 2 includes the positive electrode layer 21, the negative electrode layer 22, and the electrolyte layer 23 located between the positive electrode layer 21 and the negative electrode layer 22" may be implemented in various ways:
in one example, as shown in fig. 2, the positive electrode layer 21, the electrolyte layer 23, and the negative electrode layer 22 are sequentially stacked, so that the area of the flexible self-power-generating device 2 is small. In this example, in order to improve the contact effect of the electrolyte layer 23 with urine, the positive electrode layer 21 and the negative electrode layer 22 may have a hollow pattern, for example, a grid shape with a fixed line width, so that urine can enter the contact electrolyte layer 23 from the hollow. Alternatively, the electrolyte layer 23 is a paper electrolyte layer or a non-woven fabric electrolyte layer, and may be obtained by immersing an electrolyte liquid into paper or non-woven fabric, followed by drying.
In another example, as shown in fig. 3, the positive electrode layer 21, the electrolyte layer 23 and the negative electrode layer 22 are located on the same plane, and the positive electrode layer 21 and the negative electrode layer 22 are respectively disposed on two sides of the electrolyte layer 23, so that the electrolyte layer 23 is easier to contact with urine, and the detection effect is better. Alternatively, the positive electrode layer 21, the electrolyte layer 23, and the negative electrode layer 22 may be formed on the same flexible substrate (e.g., nonwoven fabric or paper, etc.).
Optionally, the mass fraction of the first metal powder in the first liquid metal layer as the positive electrode layer 21 is 5% to 30%, for example, 5%, 10%, 15%, 20%, 25%, and 30%, where the higher the mass fraction of the first metal powder in the first liquid metal layer is, the better the power generation effect of the flexible self-power generation device 2 is, but the higher the viscosity of the first liquid metal layer is, the more difficult the preparation is, and the selection of the above mass fractions may make the first liquid metal layer easier to prepare and the power generation effect of the flexible self-power generation device 2 be better. Similarly, the mass fraction of the second metal powder in the second liquid metal layer is 5% to 30%, for example, 5%, 10%, 15%, 20%, 25%, 30%, so that the first liquid metal layer is easier to prepare and the flexible self-generating device 2 has a better power generation effect.
Optionally, the particle size of the first metal powder is 1 nm-100 μm; the grain diameter of the second metal powder is 1 nm-100 mu m. Wherein, the particle size of first metal powder and second metal powder is too big, then difficult evenly distributed in liquid metal, can make positive pole layer 21 and negative pole layer 22's performance inhomogeneous, and the particle size undersize of first metal powder and second metal powder then can make the difficult preparation of first metal powder and second metal powder, and the cost is higher, and the selection of above particle size can make first metal powder and second metal powder easier preparation, and easier evenly distributed in liquid metal. Wherein, when a certain physical property or physical behavior of the measured particle is most similar to a homogeneous sphere (or combination) with a certain diameter, the diameter (or combination) of the sphere is taken as the particle size of the measured particle.
In addition, the liquid metal in the first liquid metal layer and the second liquid metal layer is preferably non-toxic and harmless liquid metal with a melting point lower than normal body temperature, such as gallium-indium eutectic alloy, gallium simple substance and the like. Optionally, the first liquid metal layer includes 90% by mass of gallium-indium eutectic alloy, 10% by mass of first metal powder with a diameter of 50nm, and the second liquid metal layer includes 90% by mass of gallium-indium eutectic alloy, 10% by mass of second metal powder with a diameter of 50 nm.
In addition, the first liquid metal layer and the second liquid metal layer may further contain other substances, such as a conductivity enhancing material, to improve the overall performance of the first liquid metal layer and the second liquid metal layer. Illustratively, the first liquid metal layer and the second liquid metal layer each include 10% by mass of carbon nanotubes.
The first liquid metal layer and the second liquid metal layer may be formed by spraying, printing, transferring, and the like, which is not limited in the embodiments of the present invention. The liquid metal and the first metal powder or the second metal powder can be mixed by means of ball milling and stirring.
Alternatively, the electrolyte in the electrolyte layer 23 is citric acid or acetic acid, which is less acidic and does not cause irritation to the wearer's skin. Taking the electrolyte layer 23 as a paper electrolyte layer as an example, the water-absorbent paper can be made by soaking the water-absorbent paper in a citric acid solution with a mass fraction of 15%, taking out and drying.
Optionally, the first metal powder comprises one or more of copper powder, silver powder, gold powder and platinum powder, and is preferably copper powder with low cost; the second metal powder comprises one or more of zinc powder, magnesium powder and aluminum powder, and is preferably aluminum powder. Illustratively, the first liquid metal layer comprises 90% by mass of gallium-indium eutectic alloy and 10% by mass of copper powder with a diameter of 50nm, the second liquid metal layer comprises 90% by mass of gallium-indium eutectic alloy and 10% by mass of zinc powder with a diameter of 50nm, the electrolyte layer 23 is a non-woven fabric electrolyte layer, and the electrolyte in the electrolyte layer 23 is citric acid.
