Thin film converts heat from electronics into energy

04/16/18 — Nearly 70 percent of the energy produced in the United States is wasted as heat - from exhaust pipes, high-speed electronics and other sources. Now Berkeley engineers have developed a thin-film system that can produce energy from these waste sources at unprecedented levels.

New technology could wean battery world off cobalt

04/11/18 — A research team led by Gerbrand Ceder, professor of materials science and engineering, has devised a way to build lithium battery cathodes using materials that have greater capacity, and a far lower price, than the traditional cobalt.

Chirp Microsystems acquired

03/23/18 — Chirp Microsystems, a startup enabled with technology developed at UC Davis and UC Berkeley, has been acquired by Japanese electronics giant TDK Corporation. Based in Berkeley, Chirp Microsystems makes tiny, ultra-low power sensors that function like sonar or echolocation. The micro-electromechanical systems (MEMS) technology enables extremely precise sensing and has applications in drones, robots, vehicles, smart home products, augmented reality and virtual reality systems.
