A Batteryless Sensor Chip for the Internet of ThingsA prototype sensor saves power by using transistors that never fully turn “on.” The promise of the Internet of things is, in a sense, passivity. Our homes and offices will monitor us, and respond to our needs without instruction. But for tiny wireless sensors all over us and our things to really be feasible, we’ll have to replace today’s power-needy devices with more self-sufficient alternatives.
