A sensor that measures changes in acceleration, strain, pressure, and force by converting them into electric charge, using Piezoelectric effect. Piezoelectric effect means generating electrical charge in response to applied mechanical force. The sensor does exactly according to this effect, it will convert the applied mechanical force into the electric charge, giving us various number of electrical applications. The main component of this sensor is the material which have Piezoelectric properties. As mentioned earlier the mechanical force that the sensor convert into electric charge, includes forces like acceleration, stress, strain, and pressure.
