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

Mechanical Performance of a Cascaded V-Shaped Electrothermal Actuator
International Journal of Advanced Robotic Systems, 2013 The function and performance of MEMS are affected by the output ability of the displacement and force of microactuators. The lateral deflection of cascaded V-shaped electrothermal actuators is modelled as a triple, statically indeterminate problem.

Multiphase Actuation of AC Electrothermal Micropump
Micromachines, 2023 Electrothermal micropumps apply an AC electric field to a conductive fluid within the range of 10 kHz–1 MHz to generate fluid flow. In this frequency range, coulombic forces dominate fluid interactions over opposing dielectric forces, resulting in high flow rates (~50–100 μm/s).
