A new life for mobile phones | Rajeevan Amirtharajah | TEDxUCDavis

What happens to mobile phones when they die? Instead of simply getting rid of them, Rajeevan Amirtharajah proposes that we use the wealth of technology found in these old phones to replace devices we use all the time.

Prof. Amirtharajah's research activities focus on the development and implementation of electronic systems which are powered by energy harvested from their environment. This includes the conversion of incident light (solar energy harvesting) and environmental mechanical vibrations into electrical form, power electronics to generate stable supply voltages, and load circuits which consume less than one milliwatt. These systems form the foundation for self-powered wireless sensor networks which have applications in green building design, infrastructure and environmental monitoring, medicine, and defense.

About TEDx, x = independently organized event

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
