As shown in fig. 1, an embodiment of the present invention provides a processing method, including:
sequentially inputting a plurality of detection wave signals to the sensing circuit, wherein the plurality of detection wave signals comprise a plurality of wave signals with different frequencies, the sensing circuit at least comprises a flexible pressure sensing element, and the flexible pressure sensing element generates corresponding deformation along with the change of pressure;
obtaining a plurality of feedback wave signals corresponding to the plurality of detection wave signals output by the induction circuit, wherein the plurality of feedback wave signals are used for reflecting the influence of deformation generated by the flexible pressure sensing element on the detection wave signals;
the pressure value to which the flexible pressure sensing element is subjected is determined based at least on the plurality of feedback wave signals.
For example, an inductive circuit is provided within the electronic device, which includes a flexible pressure sensing element, such as a flexible off-electronic sensor, that senses external pressure by changing the contact area between the deformable ionic material layer and the surface of the flexible conductive material, and a resistor, and may also include a dc blocking capacitor. Since a large amount of conductive ions exist in the ionic material, when the electrolyte contacts with the electrode, an interface thereof automatically forms an electric double layer interface capacitor (EDL) having super-capacitance properties. The double-layer capacitor is an Aimi-level capacitor formed by relatively arranging ions and electronsThe permittivity of the unit area of the structure is 10000 times of that of the traditional parallel flat plate capacitor. The sensing mode utilizes the ultra-high unit area permittivity on the double electric layers, so that ultra-high sensitivity is realized, and the sensing mode has strong anti-interference capability on human body and environmental capacitance noise. Further, the electronic device has abundant media resources, which can sequentially input a plurality of detection wave signals with different frequencies to the sensing circuit through the loudspeaker, when a user applies pressure to the flexible pressure sensing element by pressing the electronic device, the flexible pressure sensing element can be stressed along with the pressureThe pressure deforms, which in turn affects the voltage distribution between the flexible pressure sensing element and the resistor, resulting in a corresponding generation of a feedback wave signal by the resistor based on the plurality of detection wave signals of different frequencies. That is, the pressure of the flexible pressure sensing element will directly affect the feedback wave signal. When the electronic device receives the feedback wave signals output by the sensing circuit, the electronic device can process the feedback wave signals based on the feedback wave signals, for example, determine the shape of the signal wave formed by the feedback wave signals, determine that the flexible pressure sensing element is pressed, and calculate the pressure value of the flexible pressure sensing element.
Therefore, the electronic device in this embodiment sequentially inputs a plurality of detection wave signals with different frequencies to the sensing circuit, so as to obtain a feedback wave signal fed back by the sensing circuit based on the detection wave signals, and at least analyzes and processes the feedback wave signal based on the feedback wave signal, so that whether the user presses the flexible pressure sensing element and the pressure value received by the flexible pressure sensing element can be determined, the whole processing process is simple, fewer devices are needed, and no devices such as a signal conversion circuit, an analog-to-digital converter and the like are needed. In addition, the flexible pressure sensing element is arranged, so that the pressure sensing sensitivity can be remarkably enhanced, and the calculation accuracy of the pressure value is improved.
Further, as shown in fig. 5, the sensing circuit in the present embodiment may be configured as a resonant circuit, and the flexible pressure sensing element may be configured in the sensing circuit in the form of an equivalent capacitance, and in addition, an inductor may be configured to form a pressure sensor in cooperation with the equivalent capacitance. The capacitance change value of the equivalent capacitance is the capacitance change of the flexible pressure sensing element reflected by pressure, namely, when a user presses the flexible pressure sensing element, the equivalent capacitance generates the capacitance change, and the electronic equipment can calculate the capacitance change value based on the capacitance change, so as to calculate the pressure value of the flexible pressure sensing element based on the capacitance change value.
Specifically, as shown in fig. 2, in this embodiment, when the electronic device determines the pressure value to which the flexible pressure sensing element is subjected based on at least the plurality of feedback wave signals, the electronic device includes:
processing the plurality of feedback wave signals to obtain target parameters;
and determining the pressure value born by the flexible pressure sensing element based on the target parameter and the reference parameter corresponding to the detection wave signal.
For example, after the electronic device obtains a plurality of feedback wave signals, the feedback wave signals are processed, for example, the feedback wave signals are fit into a continuous waveform chart, and operations such as analysis are performed based on the waveform chart, so as to obtain the target parameter. Then, the electronic device can obtain a reference parameter corresponding to the detection wave signal, the reference parameter can be obtained based on a feedback wave signal generated by the sensing circuit when the flexible pressure sensing element is not subjected to pressure, then the electronic device compares and calculates based on the reference parameter and the target parameter, and finally the pressure value received by the flexible pressure sensing element is determined.
Further, as shown in fig. 3, the target parameter in the present embodiment is a resonant frequency, and processing the plurality of feedback wave signals to obtain the target parameter includes:
determining a ratio of the amplitude of each feedback wave signal to the amplitude of the corresponding detection wave signal;
determining a minimum of the plurality of ratios;
and determining the frequency corresponding to the minimum value as a target parameter, wherein the target parameter represents the current resonant frequency of the induction circuit.
For example, as described above, the sensing circuit in this embodiment is a resonant circuit, the electronic device obtains a plurality of feedback wave signals and then fits the feedback wave signals into a continuous frequency-voltage waveform, as shown in fig. 6, and processes the plurality of detection wave signals to form a continuous frequency-voltage waveform, then determines the amplitudes of each feedback wave signal and the corresponding waveform of the detection wave signal in the two waveform, and calculates the two amplitudes to obtain the ratio of the two amplitudes. Thereafter, a minimum value of the plurality of ratios is determined. This minimum value may be indicative of the weakest signal strength in the sensing circuit due to the change in impedance, which is generated by the resistor at a certain frequency. Specifically, when the flexible pressure sensing element is not pressed, the capacitance value of the equivalent capacitance C1 is C 0 The corresponding resonant frequency is f 0 Also, itThat is to say at f 0 In the vicinity, the overall impedance in the sensing circuit is maximized, and the voltage division effect is based on the impedance, so that the voltage at f 0 The voltage at resistor R is the smallest and the signal produced is the weakest. As shown in FIG. 6, f 0 When=5k, the waveform of the detection wave signal is at the lowest point. When the flexible pressure sensing element is pressed, the capacitance of the equivalent capacitor changes, e.g. C is formed 1 The impedance of the whole induction circuit is changed due to the change of the capacitance, namely the resonance frequency is changed, and the resistor R is at the resonance frequency f 1 The voltage is the smallest and the strength of the generated signal is the weakest. As shown in f 1 When=6k, the waveform of the feedback wave is at the lowest point. Further, after the electronic device determines the minimum value, the target parameter can be determined based on the frequency corresponding to the minimum value, where the target parameter is the current resonant frequency of the sensing circuit, that is, the resonant frequency generated by the sensing circuit in the process of pressing the flexible sensing element 1.
Further, as shown in fig. 4, determining, by the electronic device, the pressure value received by the flexible pressure sensing element based on the target parameter and the reference parameter corresponding to the detected wave signal in this embodiment includes:
determining a frequency difference value based on a target parameter representing the current resonant frequency of the induction circuit and a reference parameter representing the resonant frequency of a reference of the induction circuit; the reference parameter characterizes the initial resonant frequency of the induction circuit;
determining a capacitance change value based on the frequency difference value;
the pressure value to which the flexible pressure sensing element is subjected is determined based on the capacitance change value.
Specifically, the reference parameter in this embodiment is the resonant frequency generated by the sensing circuit during the period when the flexible sensing element is not pressed, and after the electronic device obtains the target parameter and the reference parameter, the frequency difference is calculated, so that the capacitance change value of the flexible sensing element is calculated based on the frequency difference, and finally the actual pressure value received by the flexible pressure sensing element is determined based on the capacitance change value.

Since a large amount of conductive ions exist in the ionic material, when the electrolyte contacts with the electrode, an interface thereof automatically forms an electric double layer interface capacitor (EDL) having super-capacitance properties. The double-layer capacitor is an Aimi-level capacitor formed by relatively arranging ions and electronsThe permittivity of the unit area of the structure is 10000 times of that of the traditional parallel flat plate capacitor. The sensing mode utilizes the ultra-high unit area permittivity on the double electric layers, so that ultra-high sensitivity is realized, and the sensing mode has strong anti-interference capability on human body and environmental capacitance noise. Further, the electronic equipment has rich media resources, which can be realized through the RamanThe horn inputs a plurality of detection wave signals with different frequencies to the induction circuit in sequence, when a user applies pressure to the flexible pressure sensing element by pressing the electronic equipment, the flexible pressure sensing element deforms along with the pressure, so that voltage distribution between the flexible pressure sensing element and the resistor is affected, and a feedback wave signal correspondingly generated by the resistor based on the detection wave signals with different frequencies is affected. That is, the pressure of the flexible pressure sensing element will directly affect the feedback wave signal.
