Question

Soon enough, say some engineers, miniature wireless sensors will be located in spots where it would be
inconvenient, to say the least, to change their batteries - inside your body, within the steel and concrete of
buildings, in the dangerous innards of chemical plants. But today, even the most robust nodes can be counted on
to last only a few years. Ideally, engineers need wireless sensors that can last forever without external power
sources or battery changes. According to research presented in December at the International Electron Devices
Meeting, in Baltimore, that dream is within reach.
