H�b```f``�a`c` Piezoelectric Sensors Piezoelectric sensors do not require any power to continuously monitor an environment. In order to read low frequency signal we need to decrease the cutoff frequency. To use a DAC series sensor, a charge amplifier is required, which turns the electri- cal charge into a corresponding output signal. Piezo Sensor A sensor that utilizes the piezoelectric effect, to measure changes in acceleration, strain, pressure, and force by converting them into electrical charge is called as a piezoelectric sensor. A piezoelectric transducer(also known as a piezoelectric sensor) is a device that uses the piezoelectric effect to measure changes in acceleration, pressure, strain, temperature or force by converting this energy into an electrical charge. Piezo sensors are ideal in anti-tamper and industrial health monitoring applications. Inverse Piezo electric effect is defined as the strain or deformation produced in certain materials when subjected to electric field. –Piezo Sensor coupled with a load resistor acts like a high pass filter.
