High sensitivity AC coupling for piezoelectric thin film Piezo vibration sensor

With a good flexibility of the sensor, the use of 28 m piezoelectric thin film, which is on the screen printing silver paste electrode, the film is laminated on the 0.125mm polyester substrate, the electrode is drawn from two press. When the piezoelectric film is in the vertical direction by the external force acting on the axis of the axis, it will produce a high strain in the film and thus will have high voltage output. LDT0 can be used as a flexible switch when it is directly used to make the product. The output of the MOSFET and CMOS circuit can be directly triggered by the output. If the element is supported and free of vibration, the element is like an accelerometer or a vibration sensor. Increasing the mass block or changing the length of the element can affect the resonance frequency and sensitivity of the sensor, and the deviation of the mass block from the axis can be obtained by the multi axis response. LDTM-028K uses a cantilever beam structure, one end is a signal to the terminal, one end of the fixed mass, is a vibration sensor with high sensitivity at low frequency.
