Review of Electrothermal Micromirrors
Micromachines, 2022 Electrothermal micromirrors have become an important type of micromirrors due to their large angular scanning range and large linear motion. Typically, electrothermal micromirrors do not have a torsional bar, so they can easily generate linear motion. In

Electrothermal actuation of NEMS resonators: Modeling and experimental validation
Journal of Applied Physics, 2023 We study the electrothermal actuation of nanomechanical motion using a combination of numerical simulations and analytical solutions. The nanoelectrothermal actuator structure is a u-shaped gold nanoresistor that is patterned on the anchor of a doubly clamped nanomechanical beam or a microcantilever resonator.

Fabrication of graphene based electrothermal cantilever actuator [PDF]
The 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 ...
