Title
Vibration-based transducer for zero-energy standby applications
Abstract
The need to extend battery life in IoT devices, self-powered sensors and autonomous nodes increasingly highlights the necessity to reduce energy consumption as much as possible. One of the main issues to resolve is therefore the reduction of power consumption of electrical appliances while in "standby" that represents a significant amount of the total power dissipation. Today, despite the concerted effort to continuously reduce standby power consumption, this is still far from being negligible. Since power management components are permanently in the ON state, their efficiency must be carefully considered and in fact the current trend is to constantly improve it with careful design at circuit level. In this paper, a novel strategy is introduced based on kinetic-to-electrical energy transduction, which aims to resolve this issue for all those applications involving vibrations. The proposed solution goes beyond the concept of the standby state itself, as it actually applies to appliances that are turned OFF. In fact, an innovative technique will be shown here where a piezoelectric device is specifically designed as a kinetic-to-electrical energy transducer, to act on a special driving circuit and then turning ON the device. Numerical analysis, laboratory characterization and experimental results of a complete working prototype will be shown.
