A Crawler Climbing Robot Integrating Electroadhesion and Electrostatic Actuation
International Journal of Advanced Robotic Systems, 2014 Previous electroadhesive climbing robots generally employed typical electromagnetic motors, which spoiled some of the advantages of electroadhesion such as it being light, thin and flexible. To improve these, an integration of electrostatic actuation and

Reduction of Electrostatic Control Voltage with a Tri-Electrode Actuator
Proceedings, 2017 We present a new tri-electrode topology for reducing the control voltage for electrostatic actuators. Conventional parallel plate actuators are dual-electrode systems, formed by the MEMS structure and the drive electrode.

Parametric Resonance in Electrostatically Actuated Micromirrors [PDF]
IEEE Transactions on Industrial Electronics, 2017 We consider an electrostatically actuated torsional micromirror, a key element of recent optical microdevices. The mechanical response is analyzed with specific emphasis on its nonlinear features. We show that the mirror motion is an example of parametric resonance, activated when the drive frequency is twice the natural frequency of the system.
