Micro‐electromechanical (MEM) switches, with advantages such as quasi‐zero leakage current, emerge as attractive candidates for overcoming the physical limits of complementary metal‐oxide semiconductor (CMOS) devices. To practically integrate MEM switches into CMOS circuits, two major challenges must be addressed: sub 1 V operating voltage to match the voltage levels in current circuit systems and...
In article number 1703621, Zheng You, Jie Yao, Junqiao Wu, and co‐workers demonstrate a micro‐electromechanical (MEM) switch with 0.2 V operating voltage and ≳106 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...
Optical fluorescence imaging is an important strategy to explore the mechanism of virus–host interaction. However, current fluorescent tag labeling strategies often dampen viral infectivity. The present study explores an in situ fluorescent labeling strategy in order to preserve viral infectivity and precisely monitor viral infection in vivo. In contrast to pre‐labeling strategy, mice are first intranasally...
