Nanoelectronics Micro energy harvesting devices
In small size or miniature applications it is sometime required to have small size batteries providing power to sensing/actuating devices. Micro energy harvesting research area will be focusing in bringing miniaturized power solutions that can be seamlessly integrated in the application. The aim is to integrate a PZT power generator converting ambient vibrations in the range of Hz-kHz into electrical energy with the full diode bridge and auxiliary circuitry to charge a 10-nF range supercapacitor that will power sensors/actuators in the application. There are various charging architectures for common battery chemistries. Given the goals of this research we would have to develop new charging methods allowing the system multiple charging/discharging cycles.
