Patent number: 9991076Abstract: Electromechanical devices described herein may employ tunneling phenomena to function as low-voltage switches. Opposing electrodes may be separated by an elastically deformable layer which, in some cases, may be made up of a non-electrically conductive material. In some embodiments, the elastically deformable layer is substantially free of electrically conductive material.

Rather, when the electrodes are close enough to one another, a tunneling current arises therebetween. The elastically deformable layer may exhibit spring-like behavior such that, upon release of the actuation voltage and/or force, the separation distance between electrodes is restored.Type: GrantFiled: January 28, 2014Date of Patent: June 5, 2018Assignee: Massachusetts Institute of TechnologyInventors: Vladimir Bulovic, Jeffrey H.
