Piezoelectric sensor : It is an electronic device that uses piezoelectric effect to measure the changes in pressure, vibration, acceleration, temperature, strain, or force by converting them to an electrical charge.
In today’s day and age electrical devices are just not limited to electrical connection in between them but have piezoelectricity as a common thing in all applications. Diesel fuel injectors, Reverse parking sensors, gas/grill igniters, ultrasonic cleaning transducers, Flow measurement sensors, acoustic guitar pickups, vibration sensors, etc. utilizes piezoelectricity.
