Patent ID: 8847287

Claim:
An electromechanical device, comprising: a first back gate and a second back gate on a first dielectric layer over a substrate; an etch stop layer covering the first back gate and a second back gate; electrodes formed in a second dielectric layer on the etch stop layer over the first back gate and the second back gate, wherein the electrodes comprise one or more gate electrodes, one or more source electrodes and one or more drain electrodes, wherein gaps are present between the source electrodes and the drain electrodes, and wherein the gate electrodes are located adjacent to the gaps, perpendicular to the source and drain electrodes; and one or more Janus components placed in each of the gaps between the source and drain electrodes, wherein each of the Janus components includes a first portion comprising an electrically conductive material and a second portion comprising an electrically insulating material, and wherein i) either the first portion or the second portion of the Janus components placed in a first one of the gaps has a fixed positive surface charge and ii) either the first portion or the second portion of the Janus components placed in a second one of the gaps has a fixed negative surface charge.
