Description

Technical Field

[0001] This invention belongs to the field of sensors, and more specifically, relates to a battery-type pressure sensor and its fabrication method. Background Technology

[0002] Pressure sensors are one of the most common types of sensors, capable of detecting external pressure signals and outputting other easily readable signals. Pressure sensors have wide applications in various fields, detecting and identifying pressures ranging from thousands of kilopascals to just a few pascals.

[0003] Currently, common pressure sensors mainly employ four mechanisms: piezoresistive, capacitive, piezoelectric, and triboelectric. Key parameters for evaluating the overall performance of a pressure sensor include sensitivity, detection range, and cyclic stability. While these four types of sensors possess excellent pressure sensing performance, the current mainstream sensing mechanisms still have certain limitations. For example, piezoresistive and capacitive sensing systems require external power supplies, and piezoelectric and triboelectric sensing systems cannot output a constant response signal in static mode. Therefore, there is an urgent need to develop new sensing mechanisms to obtain new characteristics in pressure sensors and meet the requirements of practical applications. Summary of the Invention

[0004] To address the shortcomings and improvement needs of existing technologies, this invention provides a battery-powered pressure sensor and its fabrication method, aiming to solve the technical problems that traditional pressure sensing mechanisms (piezoresistive, capacitive, piezoelectric, and triboelectric, etc.) cannot be compatible with self-powered operation and output steady-state response signals in static mode.

[0005] To achieve the above objectives, in a first aspect, the present invention provides a battery-type pressure sensor, comprising a four-layer structure formed by stacking a positive electrode, a solid electrolyte, an isolation layer, and a negative electrode; wherein the solid electrolyte and the isolation layer are located in the middle two layers; the positive electrode, the solid electrolyte, and the negative electrode are all capable of storing and releasing metal ions or hydrogen ions; the isolation layer is used to block the flow of metal ions or hydrogen ions between the positive and negative electrodes, and when the battery-type pressure sensor is subjected to external pressure regulation, the blocking effect of the isolation layer will be weakened or fail; both the positive and negative electrodes have lead terminals, and the electrical signal between the positive and negative electrodes is output to an external detection device through the two lead terminals, thereby realizing pressure detection.

[0006] Furthermore, the solid electrolyte is flexible, and its ionic conductivity changes under external pressure.

[0007] Furthermore, the solid electrolyte is any one of graphene oxide membrane, hydrogel, cellulose membrane, and composite materials thereof.

[0008] Furthermore, the solid electrolyte is obtained from cellulose or two-dimensional nanomaterials through a vacuum-assisted filtration method.

[0009] Furthermore, the insulating layer is made of insulating nanofibers.

[0010] Furthermore, the isolation layer is obtained by electrospinning.

[0011] Furthermore, the metal ion is any one of lithium ion, sodium ion, potassium ion, zinc ion and manganese ion.

[0012] Furthermore, the metal ion is a zinc ion, the positive electrode is any one of molybdenum disulfide, vanadium dioxide, vanadium pentoxide, Prussian blue analogues, and molybdenum trioxide, and the negative electrode is zinc foil.

[0013] Furthermore, the positive and negative electrodes provide energy to the battery-type pressure sensor through a redox reaction, and the maximum potential difference of the redox reaction is the maximum response voltage value of the battery-type pressure sensor.

[0014] In a second aspect, the present invention provides a method for preparing the battery-type pressure sensor described in the first aspect, comprising: preparing a positive electrode, a solid electrolyte, an isolation layer and a negative electrode material respectively; and assembling the positive electrode, the solid electrolyte, the isolation layer and the negative electrode material to obtain the battery-type pressure sensor.

[0015] In summary, the above-described technical solutions conceived in this invention can achieve the following beneficial effects:

[0016] The battery-type pressure sensor provided by this invention features a pressure-sensitive isolation layer and a solid electrolyte. When an external pressure signal is applied to the battery-type pressure sensor, the open-circuit voltage of the battery sensor changes systematically. Therefore, the magnitude of the external pressure signal can be determined based on the battery's open-circuit voltage. This technical solution allows for the manufacture of pressure sensors with simple structures, low costs, and ease of mass production, enabling accurate measurement of different pressures and achieving self-driving functionality, thus avoiding the need for large power supply equipment. The device exhibits a very short response / recovery time. Furthermore, this pressure sensor possesses advantages such as good cycle stability, long service life, and cyclic charging and discharging capability. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0027] In this invention, the terms "first," "second," etc. (if present) in the invention and the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0028] The battery-type pressure sensor provided by this invention achieves self-driving functionality while possessing excellent pressure sensing performance. The battery-type pressure sensor comprises a four-layer structure formed by stacking a positive electrode, a solid electrolyte, an insulating layer, and a negative electrode; wherein the solid electrolyte and the insulating layer are located in the middle two layers.

[0029] The battery can be a metal ion battery such as lithium-ion, sodium-ion, potassium-ion, zinc-ion, and manganese-ion, or it can be a hydrogen-ion battery. Accordingly, the positive electrode, solid electrolyte, and negative electrode in this device all need to achieve the storage and release of the corresponding metal ions or hydrogen ions.

[0030] It should be noted that for a four-layer battery-type pressure sensor, only the solid electrolyte and the insulating layer need to be located in the middle two layers. For ease of description, the following text will refer to this as... Figure 1 The specific structure shown will be used as an example for explanation.

[0031] See Figure 1 This battery-type pressure sensor has a sandwich structure, specifically comprising, from bottom to top, a positive electrode, a solid electrolyte, an insulating layer, and a negative electrode stacked together. Additionally, it may include, but is not limited to, a glass plate as a carrier, copper wires for outputting the detection signal, and a polyimide film for encapsulation. The glass carrier provides a rigid support for the battery pressure sensor and also protects it; the copper wire electrodes, contacting both ends of the battery pressure sensor, are used to output the detected electrical signal to an external detection device.

[0032] Due to the isolation effect of the porous insulating layer, the open-circuit voltage signal of the battery-type pressure sensor is zero when there is no external pressure regulation. When the device is subjected to external mechanical pressure, the isolation effect of the insulating layer will weaken or fail, thereby realizing the conversion from pressure signal to electrical signal. On the other hand, the ionic conductivity of the solid electrolyte will change accordingly under the action of external mechanical pressure, which can further improve the output electrical signal of the battery-type pressure sensor. The battery-type pressure sensor does not require an external power source to provide additional energy and can achieve self-driving function. Based on battery-pressure sensing conversion technology, the battery-type pressure sensor can realize pressure signal detection without relying on specific electrode materials and specific solid electrolytes.

[0033] The solid electrolyte material includes, but is not limited to, graphene oxide membranes, hydrogels, cellulose membranes, and their composite materials. These materials possess excellent hydrophilicity, good ionic conductivity, and good piezoresistive properties. A cellulose membrane is preferred, disposed on the positive electrode material for pressure sensing. The cellulose membrane solid electrolyte exhibits excellent ionic conductivity, providing the necessary conditions for redox reactions at the electrode. Furthermore, the ionic conductivity of the cellulose membrane solid electrolyte increases with increasing pressure; this unique change enables the superior sensing performance of battery-type sensors.

[0034] The cellulose membrane provided by this invention is prepared by the following steps:

[0035] (1) Filter 20 ml of bacterial cellulose dilution with a concentration of 10 mg / ml into a membrane;

[0036] (2) The successfully filtered cellulose membrane was soaked in zinc trifluoromethanesulfonate for 5 days.

[0037] The successfully prepared solid electrolyte cellulose membrane exhibits good hydrophilicity. A scanning electron microscope image of the PVA nanofiber surface is shown below. Figure 2 As shown, the surface scanning electron microscope image of the cellulose membrane is as follows. Figure 3 As shown, the cross-sectional scanning electron microscope image of the cellulose membrane is as follows. Figure 4 As shown in the figure. The cellulose membrane solid electrolyte provided by this invention exhibits good pressure response performance and can achieve different ionic conductivities under different pressure levels. Specific test results are as follows. Figure 5-1 and Figure 5-2 As shown.

[0038] The preferred positive electrode material is vanadium dioxide (VO2), which is disposed on a glass carrier and copper wire. The VO2 material is synthesized via a hydrothermal method, followed by mixing and grinding VO2, acetylene black, and polyvinylidene fluoride (PVDF) in a 7:2:1 ratio. The mixture is then coated onto a stainless steel mesh, and the areal density of the active material is 2 mg / cm³. 2 .

[0039] The preferred negative electrode material is zinc foil.

[0040] The insulating layer material is electrospun onto one side of the zinc foil, which is then brought into contact with the solid electrolyte. The insulating layer material is composed of insulating nanofibers, whose main function is to isolate the solid electrolyte from the electrode materials. Due to the good compression recovery properties of PVA nanofibers, the battery-type sensor exhibits good response and recovery times. Under pressure regulation, the insulating layer's blocking effect weakens, increasing the contact between the electrodes and the solid electrolyte in the battery-type pressure sensor, thus changing the output electrical signal.

[0041] The combination of VO2 and zinc foil electrodes provides a high redox potential difference, enabling a high pressure response value. Since the maximum response voltage of a battery-type pressure sensor is related to the redox potential difference between the two electrodes, some of the response performance of a battery-type pressure sensor is related to the choice of electrode materials.

[0042] The device assembly provided by this invention is mainly in accordance with Figure 1The structure shown is assembled as follows. It includes: Anode material: providing energy to the device through a redox reaction. Solid electrolyte film: serving to conduct ions while isolating electrons (the solid electrolyte film is attached to the anode surface); this solid electrolyte is also sensitive to external pressure, and changes in external pressure will lead to changes in the internal structure and ionic conductivity of the solid electrolyte. Isolation layer: the isolation layer is attached to the surface of the solid electrolyte film. This isolation layer has high porosity, and its isolation effect will decrease under external pressure, resulting in a further enhancement of the voltage signal of the battery-type pressure sensor. Positive electrode material: the positive electrode is attached to the other side of the isolation layer, also providing energy to the device through a redox reaction. The open-circuit voltage (or short-circuit current) of the device will change in real time under external pressure control. Pressure can modulate the isolation effect of the isolation layer and the ion transport of the solid electrolyte, causing a significant change in the ionic conductivity of the battery-type pressure sensor, thereby modulating the open-circuit voltage or short-circuit current of the battery-type pressure sensor. The electrical signal can then be read by an external voltage detection device to achieve dynamic detection of pressure changes. The output pressure detection signal is a voltage signal or a current signal; the output voltage signal is related to the positive and negative electrode materials and corresponds one-to-one with the detected pressure signal.

[0043] In addition, the lifespan of the device can be extended through cyclic charging and discharging.

[0044] The response / recovery time of the device under pressure is as follows Figure 6 As shown. The stepped pressure test of the battery sensor is as follows. Figure 7 As shown, the electrical signal output under different pressures is as follows: Figure 8 As shown, long-term static pressure tests under different pressures are performed as follows: Figure 9 As shown.

[0045] In summary, the battery-powered pressure sensor of this application greatly optimizes the output electrical signal, effectively improving the response value, response time, and recovery time to pressure. This novel battery-powered pressure sensor technology requires no complex processes, has a simple device structure, and can achieve self-driving functionality, thus avoiding the use of large power supply equipment.
