Low-cost embeddable smart sensor networks for accurate real-time ultrasonic-based battery diagnostics

Precourt Institute for Energy

PI: Fu-Kuo Chang, Aeronautics and Astronautics

People will increasingly depend on high-energy battery packs, from electric cars to storing renewable energy, but batteries are prone to premature degradation and failure. The engineers on this project will develop micro-fabricated sensor network patches that can be embedded in or mounted on any batteries using ultrasonic inspection. If successful, such networked devices could inexpensively improve the performance, safety and durability of energy storage for many applications.
