A batteryless chemical sensor is developed by Xianying Wang, Yinmin Wang, and co-workers on p. 117. The nanosensor relies on dynamic interactions of molecules with semiconductor nanowire surfaces that can induce electrical voltages between segments of nanowires. The work overcomes the power requirement of traditional sensors and has the advantage of simplicity, high sensitivity, and quickness in detecting various molecules.
