Design of Energy-Saving PZT Drive Amplifiers for Mobile and Wearable Physical Assists

An energy-efficient circuit for driving PZT actuators using a charge recovery technique is explored in this paper. Mobile and wearable devices for physical assists requiring extended battery life and/or minimal battery weight will benefit from this technology. PZT is a capacitive transducer and can...
