resonating power transducer

A laser-micromachined multi-modal resonating power transducer for wireless sensing systems
NNH Ching, HY Wong, – Sensors and Actuators A: … 1, the mechanical input vibration and frequency, the transducer spring-mass motion, and the
electrical output of the transducer were measured … 4, for a “spiral” spring, the generator gave
relatively high voltage at higher frequencies even though the vibration amplitude was almost
