Energy harvesting devices convert mechanical energy into electrical energy. They are of great interest to supply small autonomous systems such as embedded sensors.
CEDRAT TECHNOLOGIES has developed several types of piezoelectric actuators displaying interesting properties for vibration and shock energy harvesting. Among them, Amplified Piezoelectric Actuators (APA®) combined with a mass operating in a proof mass mode are especially interesting piezoelectric generators :
Using this approach and its standard actuators, CEDRAT TECHNOLOGIES can easily define customised piezo generators for vibration or shock energy harvesting.
CEDRAT TECHNOLOGIES has also developed complete energy harvesting devices including the electronics. One of the examples given hereafter consists in a piezo generator used to supply a sensor embedded on aircraft and its RF emitter to broadcast the sensor signal.
