In this paper, we present a new structure of a micromachined tunable capacitor using a combination of piezoelectric and electrostatic parallel-plate actuators. Electrostatic parallel-plate capacitors have a low capacitive tuning ratio due to the "pull-in" instability. Therefore, to increase the capacitive tuning ratio, an electrostatic parallel-plate …

The VALVCON ESR Series electric actuator provides an internal bank of super-capacitor power storage devices that never need replacement. It''s designed for two-position operation providing true two-wire control: When the actuator is energized it drives to one position; when de-energized the actuator powers itself to the other position.
Figure 8.2.3 : Capacitor electric field with fringing. From Equation ref{8.4} it is obvious that the permittivity of the dielectric plays a major role in determining the volumetric efficiency of the capacitor, in other words, the amount of capacitance that can be packed ...
There are four main varieties of linear actuator: electric, hydraulic and pneumatic. Each variety has its own unique characteristics: Electric linear actuators. Electric linear actuators are precise, efficient, and controllable with a wide range of force output and speed options. They are also relatively quiet and low-maintenance, making …
