A V-Shaped Actuator Utilizing Electrostatic Force

Actuators, 2018
In this study, we propose a new ‘V’-shaped actuator with two panels and experimentally and theoretically investigate its actuation to find the most efficient structure. The V-shaped actuator operates like a seesaw.

Modeling and Control of Electrowetting Induced Droplet Motion

Micromachines, 2012
In this paper, a general methodology for the dynamic study of electrostatically actuated droplets is presented. A simplified 1D transient model is developed to investigate the transient response of a droplet to an actuation voltage and to study the ...

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.

Cricket Inspired High Efficiency MEMS Speakers

Proceedings, 2017
We report on the realization of a biomimetic MEMS speaker inspired by field crickets. This speaker is at least five times thinner and four times more efficient than the current dynamic speakers used in portable electronics.

Size-dependent behavior of a MEMS microbeam under electrostatic actuation

Vietnam Journal of Mechanics, 2022
The size-dependent behavior of a silicon microbeam with an axial force in MEMS is studied using a nonlinear finite element procedure. Based on a refined third-order shear deformation theory and the modified couple stress theory (MCST), nonlinear ...

Single-Electrode Electrostatic Repulsion Phenomenon for Remote Actuation and Manipulation

Research
One of the fundamental principles of electrostatics is that an uncharged object will be attracted to a charged object through electrostatic induction as the two approaches one another.

Pulsed Digital Oscillators for Electrostatic MEMS

, 2012
This paper introduces a new actuation scheme for implementing Pulsed Digital Oscillators (PDOs) for electrostatic MEMS resonators. In this scheme, the capacitance of the device is biased with a voltage and it is periodically sampled. Short pulses of zero
