Electrothermally Actuated Microbeams With Varying Stiffness
Volume 4: 22nd Design for Manufacturing and the Life Cycle Conference; 11th International Conference on Micro- and Nanosystems, 2017We present axially loaded clamped-guided microbeams that can be used as resonators and actuators of variable stiffness, actuation, and anchor conditions. The applied axial load is implemented by U-shaped electrothermal actuators stacked at one of the beams edges.

A bimorph electrothermal actuator for micromirror devices
SPIE Proceedings, 2015The research and development results along the characteristics of the micro-mirror element driven by thermal microactuator are presented. This work shows that for calculating micro-mirror element deflection is crucial for consideration the temperature distribution along the length of the micromirror element. The calculation of the superheat temperature

Modelling surface-micromachined electrothermal actuators
Canadian Journal of Electrical and Computer Engineering, 2004A method for the accurate simulation of electrothermal actuators is presented. The model accounts for variations in material parameters that occur over the temperature range at which polysilicon electrothermal actuators are operated. The paper then presents the steps necessary to perform a sequential electrothermal-mechanical analysis using ANSYS ...

Out-of-plane electrothermally actuated bistable buckled microbridge actuator
IEEE Sensors, 2005., 2005In this paper, we report the design, simulation, and fabrication of a novel electro-thermally actuated buckled micro-bridge for out of plane-actuation. The new structure consists of a beam supported by four springs and four 'legs' at the supporting ends.

An Electrothermally Actuated MEMS Braille Dot
2019With some recent attempts on development of micro tactile displays, the realization of portable Braille is becoming more feasible. Such tactile displays can help visually impaired individuals to read and comprehend patterns by using the sense of touch. The current proposed designs for such tactile displays mainly use fluid expansion to enhance the out ...

Soft electrothermal actuators using silver nanowire heaters
Nanoscale, 2017Low-voltage and extremely flexible electrothermal bimorph actuators were fabricated in a simple, efficient and scalable process. The bimorph actuators were made of flexible silver nanowire (AgNW) based heaters, which exhibited a fast heating rate of 18 °C s-1 and stable heating performance with large bending.

Development of an all-metal electrothermal actuator and its applications
SPIE Proceedings, 2004The in-plane motion of microelectrothermal actuator (''heatuator'') has been analyzed for Si-based and metallic devices. It was found that the lateral deflection of a heatuator made of a Ni metal is about ;60% larger than that of a Si-based actuator under the same power consumption.
