Modeling of Beam Electrothermal Actuators

Journal of Microelectromechanical Systems, 2020
Beam electrothermal actuators amplify the thermal expansion of pre-shaped beams and use the symmetrical structure to create a linear motion. These actuators, including V and Z shapes, are widely used in microsystems. Explicit analytical expressions are derived in this paper governing the structural deformation of these actuators due to electrothermal ...

Scaling of folded electrothermal actuators

2010 IEEE 23rd International Conference on Micro Electro Mechanical Systems (MEMS), 2010
Scaling of folded electrothermal actuators for optical applications in arrays from 1 mm to 50 µm pitch is presented. A 1-D model of a folded electrothermal actuator is presented to demonstrate the inverse scaling law for power with array pitch and linear scaling for rotational scan range. Metal/oxide bimorph actuators with discrete heaters are shown to

A micromachined RF microrelay with electrothermal actuation

Sensors and Actuators A: Physical, 2003
Abstract This paper reports the design and fabrication of a low-voltage lateral-contact microrelay for RF applications. The silicon surface micromachined relay utilizes electrothermal actuators and low-stress silicon nitride as a structural connection as well as electrical and thermal isolation. The sidewall contact is sputtered gold.
