Electrothermally-Actuated Micromirrors with Bimorph Actuators—Bending-Type and Torsion-Type [PDF]

open access: yesSensors, 2015
Three different electrothermally-actuated MEMS micromirrors with Cr/Au-Si bimorph actuators are proposed. The devices are fabricated with the SOIMUMPs process developed by MEMSCAP, Inc. (Durham, NC, USA). A silicon-on-insulator MEMS process has been employed for the fabrication of these micromirrors.

Fabrication of graphene based electrothermal cantilever actuator [PDF]

open access: yesThe 8th Annual IEEE International Conference on Nano/Micro Engineered and Molecular Systems, 2013
A novel actuator has been fabricated using graphene and graphene oxide composite paper as building blocks. The two materials have nearly equal Young's modulus, however a large displacement was observed during the electromechanically driven operation, which was attributed to great difference in coefficient of thermal expansion of graphene paper and ...
