FEM Assisted Design of Novel Electrothermal Actuators

Deladi S., Krijnen G., Elwenspoek M., University of TWente, NL

The demand for powerful actuators, which can be embedded into MEMS devices draws attention to electrothermal actuators, although there can be drawbacks such as the heat created during actuation. The main advantage is the low [...]

Low Volume, Large Force (>1mN) and Nanometer Resolution Electrostatic Microactuator for Low Displacement Applications

Sarajlic E., Berenschot E., Krijnen G., Elwenspoek M., University of TWente, NL

An electrostatic microactuator suitable for low displacement applications is successfully fabricated and tested. A large force (>1mN) with a controllable nanometer resolution step (

Three Dimensional Adhesion Model for Arbitrary Rough Surfaces

Deladi S., Krijnen G., Tas N.R., Elwenspoek M.C., University of TWente, NL

We present a 3D adhesion model based on the JKR theory applied locally for all contacting asperity couple and the calculations account the van der Waals interaction beside the externally applied force. Thus, equilibrium of [...]
