The following uses an electronic device as the execution subject to illustrate the dielectric elastomer tracking system control method provided in this application embodiment.

[0025] This application provides a dielectric elastomer waist-tracking system. The dielectric elastomer waist-tracking system can be deployed in a seat, such as a car seat, gaming seat, therapeutic seat, or any theoretically feasible type of seat; this application does not impose any specific limitations on this.

[0026] like Figure 1As shown, the dielectric elastomer waist tracking system 100 includes: a control chip 110, a thin film pressure sensor 120, a dielectric elastomer 130, and two layers of flexible electrodes (flexible electrode 141 and flexible electrode 142). Dielectric elastomer 130 is located between flexible electrode 141 and flexible electrode 142; A thin-film pressure sensor 120 is superimposed on the outside of any layer of flexible electrode; The control chip 110 is connected to the thin-film pressure sensor 120 and the two layers of flexible electrodes, respectively; The thin-film pressure sensor 120 is used to acquire real-time pressure data and send the real-time pressure data to the control chip 110; The control chip 110 is used to control the generation of a target voltage between the two flexible electrodes (flexible electrode 141 and flexible electrode 142) based on real-time pressure data. Dielectric elastomer 130 is used to generate deformation based on target voltage.

[0027] In actual implementation, the two layers of flexible electrodes can include several pixel locations. The control chip can be independently connected to the flexible electrode at each pixel location to provide independent power to each flexible electrode. For example, the control chip can be independently connected to the flexible electrode at each pixel location via a flexible printed circuit (FPC).

[0028] In practical applications, the dielectric elastomer can be a silicone elastomer, acrylic elastomer, siloxane elastomer, or any theoretically feasible elastomer; this application does not impose any specific limitations on this. The dielectric elastomer can deform in response to the voltage generated between the two flexible electrodes.

[0029] In some embodiments, the control chip can be connected to the thin-film pressure sensor in any theoretically feasible manner. For example, the control chip can be connected to the thin-film pressure sensor via wired communication or via wireless communication; this application does not impose specific limitations in this regard. For example, the control chip can be connected to the thin-film pressure sensor via the I2C communication protocol.

[0030] In some embodiments, the control chip can be used to determine the state and value of the target voltage based on real-time pressure data, wherein the state of the target voltage characterizes the type of dielectric elastomer deformation and the value of the target voltage characterizes the degree of dielectric elastomer deformation.

[0031] In some embodiments, the dielectric elastomer tracking system may further include a safety isolation layer for encapsulating the thin-film pressure sensor, the dielectric elastomer, and two layers of flexible electrodes. The safety isolation layer is constructed using 0.2 mm PET+Al vapor deposition, has 3 kV insulation, IP54 waterproof adhesive backing, and edge sealant.

[0032] According to the embodiments of this application, the dielectric elastomer waist-tracking system controls the generation of a target voltage between two flexible electrodes by a control chip based on real-time pressure data obtained from a thin-film pressure sensor. This causes the dielectric elastomer between the two flexible electrodes to deform based on the target voltage. The dielectric elastomer is then controlled to produce corresponding deformation based on real-time pressure data applied by the user's body to the thin-film pressure sensor, thereby improving the fit between the system and the user's body.

[0033] In some embodiments, each of the thin-film pressure sensor, the flexible electrode, and the dielectric elastomer includes a plurality of pixel positions, and each pixel position of the thin-film pressure sensor, the flexible electrode, and the dielectric elastomer corresponds to a pixel position; the real-time pressure data includes pixel position information and real-time pressure value; the control chip can be used to: determine the value of the target voltage based on the real-time pressure value; and control the corresponding pixel positions in the two layers of flexible electrodes to generate the target voltage based on the pixel position information.

[0035] In some embodiments, the control chip can pre-store pressure-voltage relationship curves, which represent the mapping relationship between each pressure value and its corresponding voltage. The control chip can be used to determine the voltage value corresponding to the real-time pressure value in the pressure-voltage relationship curve as the target voltage value based on the real-time pressure value.

[0036] In actual execution, pixel position information can be the information of the pixel position that detects the real-time pressure value.

[0037] In some embodiments, the control chip can be used to determine the pixel position where a target voltage is applied to the two flexible electrodes based on pixel position information. For example, if the pixel position information is a first pixel position 212, the target voltage is determined to be applied between a second pixel position 222 and a third pixel position 232 of the two flexible electrodes.

[0038] According to the dielectric elastomer waist-tracking system of this application embodiment, the control chip controls the corresponding pixel position between two flexible electrodes to generate a target voltage based on the real-time pressure data obtained by the thin-film pressure sensor. This causes the dielectric elastomer at the corresponding pixel position between the two flexible electrodes to deform based on the target voltage.

[0041] In some embodiments, the control chip can be used to store a first pressure-voltage relationship table, which includes a plurality of pressure values ​​greater than a preset pressure threshold and a voltage value corresponding to each pressure value, wherein each voltage value is a first state. The control chip can be used to determine the voltage value corresponding to the real-time pressure value in the first pressure-voltage relationship table as the target voltage value when the real-time pressure value is greater than the preset pressure threshold.

[0042] In some embodiments, the control chip can be used to store a second pressure-voltage relationship table, which includes a plurality of pressure values ​​less than or equal to a preset pressure threshold and a voltage value corresponding to each pressure value, wherein each voltage value is a second state. The control chip can be used to determine the voltage value corresponding to the real-time pressure value in the second pressure-voltage relationship table as the target voltage value when the real-time pressure value is less than or equal to the preset pressure threshold.

[0043] According to the dielectric elastomer waist-tracking system of this application embodiment, the control chip controls the corresponding pixel position between two flexible electrodes to generate a target voltage based on the real-time pressure data obtained by the thin-film pressure sensor. This causes the dielectric elastomer at the corresponding pixel position between the two flexible electrodes to deform based on the target voltage. Based on the real-time pressure data applied by the user's body to the thin-film pressure sensor, the dielectric elastomer is controlled to generate corresponding deformation locally, thereby improving the fit with the user's body.

[0044] In some embodiments, the dielectric elastomer is used to generate deformation at the pixel location based on the target voltage at each pixel location.

[0045] In some embodiments, for each pixel location, a dielectric elastomer is used to create a depression at the pixel location when the target voltage at that pixel location is in a first state.

[0046] In some embodiments, for each pixel location, a dielectric elastomer is used to generate a bulge at that pixel location when the target voltage at that pixel location is in a second state.

[0047] According to the dielectric elastomer waist-tracking system of this application embodiment, the control chip controls the corresponding pixel position between two flexible electrodes to generate a target voltage based on the real-time pressure data obtained by the thin-film pressure sensor.

For example, the control chip can be connected to the thin-film pressure sensor via wired communication or via wireless communication; this application does not impose specific limitations in this regard. For example, the control chip can be connected to the thin-film pressure sensor via the I2C communication protocol.

[0054] Step 320: Based on real-time pressure data, generate a target voltage; the target voltage is used to control the deformation of the dielectric elastomer.

[0055] In some embodiments, the control chip can determine the state and value of the target voltage based on real-time pressure data. The state of the target voltage characterizes the type of deformation of the dielectric elastomer, and the value of the target voltage characterizes the degree of deformation of the dielectric elastomer.

[0056] In practical applications, the dielectric elastomer can be a silicone elastomer, acrylic elastomer, siloxane elastomer, or any theoretically feasible elastomer; this application does not impose any specific limitations on this. The dielectric elastomer can deform in response to the voltage generated between the two flexible electrodes.

Based on the real-time pressure data applied by the user's body to the thin-film pressure sensor, the dielectric elastomer is controlled to generate corresponding deformation locally, thereby improving the fit with the user's body.

[0064] In some instances, when the real-time pressure value exceeds a preset pressure threshold, the target voltage is set to a first state; the target voltage in the first state is used to cause the dielectric elastomer to indent. or When the real-time pressure value is less than or equal to the preset pressure threshold, the target voltage is set to the second state; the target voltage in the second state is used to cause the dielectric elastomer to bulge.
