Seesaw type actuator using balancing between electrostatic force, elasticity, and gravity

A seesaw-lever force-balancing suspension design for space and terrestrial gravity-gradient sensing

Atomic force microscope based biomolecular force-clamp measurements using a micromachined electrostatic actuator.

The authors describe a method for biomolecular force clamp measurements using atomic force microscope (AFM) cantilevers and micromachined membrane-based electrostatic actuators. The actuators comprise of Parylene membranes with embedded side actuation electrodes and are fabricated on a silicon substrate. The devices have a displacement range of 1.8 μm with 200 V actuation voltage, and displacem...

A Bi-Directional Out-of-Plane Actuator by Electrostatic Force

Presented in this paper is a bi-directional out-of-plane actuator which combines the merits of the electrostatic repulsive principle and the electrostatic attractive principle. By taking advantage of the electrostatic repulsive mode, the common “pull-in” instability can be lessened to enlarge the displacement, and by applying the electrostatic attractive mode, the out-of-plane displacement is f...

Electrostatic self-force in (2+1)-dimensional cosmological gravity

Point sources in (2+1)-dimensional gravity are conical singularities that modify the global curvature of the space giving rise to selfinteraction effects on classical fields. In this work we study the electrostatic self-interaction of a point charge in the presence of point masses in (2+1)-dimensional gravity with a cosmological constant Λ. Exact expressions are obtained for the self-force on t...
