In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail by referring to the following examples.
When the present application refers to the ordinal numbers "first", "second", "third" or "fourth", etc., it should be understood that this is done for differentiation only, unless it is clear from the context that the order is actually expressed.
As shown in fig. 1 to 10, an embodiment of the present invention provides a stretchable power generation apparatus, including: base member 1, set up triboelectric layer 2 and the static response layer 3 in base member 1, triboelectric layer 2 is separated by base member 1 with static response layer 3, wherein:
a triboelectric layer 2 including a liquid storage chamber 201 and an openable and closable chamber 202 which are arranged side by side in the same extending direction as the base 1, the liquid storage chamber 201 and the openable and closable chamber 202 being communicated through a connecting passage 203, the liquid storage chamber 201 being filled with an electriferous liquid; when the substrate 1 is stretched in the extending direction, the openable and closable chamber 202 is in the open chamber 2021 state, the electrification liquid flows to the open chamber 2021, when the substrate 1 is released and retracted, the openable and closable chamber 202 is in the closed chamber 2022 state, and the electrification liquid flows back to the liquid storage chamber 201;
the electrostatic induction layer 3 includes a first electrode 301 disposed opposite to the liquid reservoir 201, and a second electrode 302 disposed opposite to the openable and closable chamber 202.
With the stretchable power generation device of the present embodiment, as shown in fig. 9 and 10, when the power generation device is mechanically pulled along the extending direction of the substrate 1, the openable and closable chambers 202 in the friction generating layer 2 are opened to form the individually opened chambers 2022, and the generated electric liquid spontaneously flows into the opened chambers 2022 from the liquid storage chamber 201 under the negative pressure. Due to the triboelectric effect, induced charges are generated on the surface of the substrate 1 at the bottom during the flow of the electrization liquid. Meanwhile, due to the principle of electrostatic induction, the two electrodes of the electrostatic induction layer 3 can sense the change of the induced charges above, so that a potential difference is generated between the two electrodes, and in order to shield the potential difference, electrons can flow from one electrode to the other electrode through an external circuit, so that a current signal is generated. When the traction force is released, the open chamber 2022 is spontaneously closed to form the closed chamber 2021 along with the retraction of the substrate 1, the electrification liquid is squeezed back to the liquid storage chamber 201, the induced charge is changed again, and a reverse current is generated. When a mechanical traction is applied periodically, a continuous alternating electrical signal will be generated.
Compared with the prior art, the power generation device capable of stretching to generate power adopts a friction power generation mode of a double-layer structure of the friction power generation layer 2 and the static induction layer 3, can eliminate the limitation that most of the previous stretchable friction power generation devices can only generate power in a single-electrode working mode, does not need to be grounded, can normally work in a humid or even liquid environment, and has wider application scenes in practical application. In addition, in a non-humid environment, the power generation device in the technical scheme can also generate power in a single-electrode mode, namely, the power generation device generates power by contacting and separating with a target object.
As shown in fig. 1 to 8, in the embodiment of the present invention, optionally, the substrate 1 is provided with a receiving groove (not shown), the receiving groove has a plurality of elastic material blocks 4 therein, each elastic material block 4 includes a fixing surface fixed to a groove wall of the receiving groove, and an abutting surface abutting against the adjacent elastic material block 4;
the Young modulus of the material of the substrate 1 is smaller than that of the material of the elastic material blocks 4, when the substrate 1 is stretched along the extending direction, the two adjacent elastic material blocks 4 are separated, the abutting surfaces and the groove walls of the accommodating groove form an opening chamber 2022, and the electric liquid flows to the opening chamber 2022; when the substrate 1 is released and retracted, the two adjacent elastic material blocks 4 abut against each other to form a closed chamber 2021, and the electrolyte flows back to the liquid storage chamber 201.
Young's modulus is a physical quantity that characterizes the tensile or compressive strength of a material within its elastic limits, and is the modulus of elasticity in the machine direction, which is also a term in material mechanics. According to hooke's law, the stress is proportional to the strain within the elastic limits of an object, and the ratio is called the young's modulus of a material, which is a physical quantity characterizing the properties of the material and depends only on the physical properties of the material itself. The magnitude of the Young's modulus indicates the rigidity of the material, and the larger the Young's modulus, the less likely it will deform.
In the present embodiment, since the young's modulus of the material of the substrate 1 is smaller than the elastic modulus of the material of the elastic material block 4, the two have different deformation amounts when being stretched. Thus, when the substrate 1 is stretched along the extending direction, the two adjacent elastic material blocks 4 are separated, and the abutting surfaces and the groove walls of the accommodating groove form an opening chamber 2022; when the substrate 1 is released and retracted, the two adjacent elastic material blocks 4 abut to form a closed chamber 2021, and the electrification liquid is squeezed and flows back to the liquid storage chamber 201.
One embodiment of the openable and closable chamber 202 is illustrated by taking the substrate 1 as a silicone substrate and the elastic material block 4 as a polydimethylsiloxane layer. Firstly, a containing groove is arranged on a substrate 1; then, filling polydimethylsiloxane into the accommodating groove, wherein the polydimethylsiloxane can be spontaneously crosslinked and fixed with the wall of the silica gel groove of the accommodating groove in the curing process; finally, the solid polydimethylsiloxane is cut off, so that the cut-off part can stretch and expand along with the bottom silica gel when being stretched, thereby forming cavities, and a plurality of openable and closable cavities 202 can be constructed.
In any embodiment of the present invention, optionally, a dimension d1 of liquid storage chamber 201 perpendicular to its extending direction is smaller than a dimension d2 of openable and closable chamber 202 perpendicular to its extending direction.
By making the dimension d1 of liquid storage chamber 201 perpendicular to its extending direction smaller than the dimension d2 of openable and closable chamber 202 perpendicular to its extending direction, for example, 1/4d 2. ltoreq. d 1. ltoreq. 1/2d2 can be satisfied. Therefore, the electrification liquid in the barrier liquid chamber 201 can flow into the opening chamber 2022 as much as possible, and the power generation efficiency is effectively improved.
As shown in fig. 3 and 7, in the embodiment of the present invention, optionally, the dimension L1 of the connecting channel 203 along the extending direction thereof satisfies: 1/3d2 is not less than L1 is not less than d 2.
In the present embodiment, the sizes of the liquid storage chamber 201, the openable and closable chamber 202, and the connecting passage 203 in the triboelectric layer 2 are enlarged or reduced according to the change of the overall size of the power generation device. Therefore, by controlling the length of the connection passage 203 to be two-half to two-third of the width of the openable and closable chamber 202, the reservoir 201 and the openable and closable chamber 202 can be surely separated.
As shown in fig. 3, 4, 7 and 8, in any embodiment of the present invention, the interval between the friction generating layer 2 and the static induction layer 3 is optionally 100 μm to 2 mm; and/or the thickness of the substrate 1 on the peripheral side of the friction generating layer 2 and the static induction layer 3 is set to be 500 μm to 3 mm.
In each embodiment of the technical scheme, the substrate 1 plays roles of connection and insulation packaging at the same time, so that the spacing layer of the substrate 1 between the friction generating layer 2 and the static induction layer 3 is set to be 100 micrometers-2 mm; the thickness of the substrate around the outer peripheries of the triboelectric layer 2 and the electrostatic induction layer 3 is controlled to be 500 μm to 3 mm.
With continued reference to fig. 3, 4, 7, and 8, in an embodiment of the present invention, optionally, the projection of the reservoir 201 onto the first electrode 301 falls within the boundary of the first electrode 301, and the projection of the openable and closable chamber 202 onto the second electrode 302 falls within the boundary of the second electrode 302.

In order to realize the triboelectric effect to the maximum extent, the liquid with the largest electronegativity difference with the polymer matrix needs to be selected as the electrification liquid. Preferably, the electrification liquid is deionized water; in addition, the electrification liquid can also be an ionic solution or various organic solutions with different polarities, such as ethanol, ethylene glycol, carbon tetrachloride, oil and the like.
In any embodiment of the present invention, the electrode material of the static induction layer may be selected from lithium chloride, sodium chloride solution and other ion conductive solutions; or, liquid conductive metals such as gallium indium tin; or, the polymer elastomer is doped with conductive materials such as carbon nanotubes and silver nanowires; or a conductive hydrogel such as polyacrylamide lithium chloride hydrogel.
Further, when the electrode material of the static induction layer is an ion conducting solution, the concentration of the ion conducting solution is 1-8 mol/L. So that the electrode can sense the change of the induced charge to a greater extent, thereby further improving the power generation efficiency.
In any embodiment of the present invention, optionally, the electrode thickness h1 of the static induction layer and the depth h2 of the liquid storage chamber satisfy: h1 is not more than 1/2h 2.
When the electrode material of the static electricity induction layer is an ion conductive solution, the electrode thickness h1 of the static electricity induction layer is selected to be within the above range, so that smooth filling of the conductive ion solution is realized when the electrode of the static electricity induction layer is formed.
When the electrode of the static induction layer is made of liquid metal, silver nanowires, carbon nanotubes and other materials, the thickness of the electrode is not required under the condition of ensuring the conductivity of the electrode, and the electrode can be very thin.
As shown in fig. 1 to 8, in the embodiment of the present invention, optionally, the power generation device further includes a first lead 5 connected to the first electrode 301, and a second lead 6 connected to the second electrode 302.
In each embodiment of the technical scheme, the structure of the power generation device capable of generating power by stretching can be effectively simplified by connecting the two leads with the corresponding electrodes respectively.
Based on the same inventive concept, the invention also provides a wearable device comprising the stretchable power generation device.

Therefore, the wearable device can be widely applied to damp and underwater related application scenes, such as diver motion signal monitoring, underwater motion energy acquisition and the like, and the application range is wider.

Deionized water is adopted as the electrification liquid in the liquid storage chamber 201, and a 1mol/L sodium chloride solution is adopted as the ionic conduction solution in the electrostatic induction layer 3. The wearable device comprising the power generation device capable of stretching to generate power is fixed at the joint of a human body, and when the human body moves, the wearable device stretches and deforms along with the stretching of the joint to generate corresponding output, so that the power generation device capable of stretching to generate power can be used as a wearable energy collection device. Meanwhile, due to the good mechanical response characteristic of the device, the stretchable power generation device can also be applied to a human body motion sensing device for monitoring the motion condition of the human body joint.
In addition, the stretchable power generation device in the technical scheme adopts the design of an upper-lower double-layer structure of the frictional electrification layer 2 and the electrostatic induction layer 3, and utilizes the characteristic of generating power by utilizing the reciprocating motion of the electrification liquid, so that the stretchable power generation device is different from the traditional single-electrode mode stretchable power generation device, the influence of the humid and liquid environment on the stretchable power generation device in the technical scheme is not obvious, and the stretchable power generation device has good working performance under water, so that the stretchable power generation device can be more widely applied to humid and underwater related application scenes, such as diver movement signal monitoring, underwater movement energy acquisition and the like.
