Stretchable Thin Film Mechanical‐Strain‐Gated Switches and Logic Gate Functions Based on a Soft Tunneling Barrier (Adv. Mater. 41/2021)

Abstract

Strain-Gated Switching Mechanical-strain-gated electric switches play a key role in sensing, soft robotics, and stretchable electronics. They typically operate with an “off-switch” function, and exhibit a decrease in conductivity upon an applied strain. In article number 2104769, Soosang Chae, Andreas Fery, and co-workers demonstrate a thin-film architecture that features the inverse behavior: “on-switch”: a strain-induced transition from insulating to metallic conductivity, spanning nine orders of magnitude in conductivity.
