Harvesting energy for self-sustaining lithium-ion batteries

Keywords:lithium-ion battery  system-in-package  micro-systems  harvesting energy 

Portable micro-systems continue to integrate more functions into smaller devices resulting in low energy levels and short operational lives. Researchers and industry alike are therefore considering harvesting energy from the surrounding environment as a means of offsetting this energy deficit. The fact is, even with all its features, the stored energy in micro-scale systems is simply not sufficient to sustain extended lifetimes. Moreover, longer-lasting batteries call for self-sustaining and self-powered micro-scale system-in-package (SiP) solutions.

This article presents what the latest research from Georgia Tech discovered about a harvesting and self-sustaining system-in-package (SiP) solution that harnesses energy for lithium-ion batteries. Particular detail is paid to the electrostatic generator, the proposed harvesting circuit, and the resulting energy gain.
