Abstract

Abstract : In article number1703621, Zheng You, Jie Yao, Junqiao Wu, and co‐workers demonstrate a micro‐electromechanical (MEM) switch with 0.2 V operating voltage and ≳10 6 safe operating cycles in ambient air, which is mainly enabled by the abrupt phase transition of nanolayered vanadium dioxide slightly above room temperature. This device is also used to demonstrate a temperature alarm/switch with ultralow power consumption. Such phase‐transition MEM switches would open possibilities for sub 1 V hybrid integrated devices/circuits/systems and ultralow power consumption devices for practical applications.
