Problems solved by technology

[0002] At present, typical motion sensors generally include piezoresistive motion sensors, capacitive motion sensors and piezoelectric motion sensors. Among them, piezoresistive motion sensors are made of the piezoresistive effect of single crystal silicon materials, which are greatly affected by temperature and process. It is more complex and expensive; the capacitive motion sensor uses a capacitor with variable parameters as the force sensitive element, and its output is nonlinear, and the parasitic capacitance and distributed capacitance have a great influence on the sensitivity and measurement accuracy, and the connection circuit is more complicated; The electric motion sensor is made of the piezoelectric effect of the piezoelectric material, which is easily disturbed by the sound; and its output impedance is high, the output signal is weak, and the sensor output signal needs to be amplified by the amplifier circuit before it can be sent to the detection circuit for detection
