Surface micromachined electrostatically actuated micro peristaltic pump.

An electrostatically actuated micro peristaltic pump is reported. The micro pump is entirely surface micromachined using a multilayer parylene technology. Taking advantage of the multilayer technology, the micro pump design enables the pumped fluid to be isolated from the electric field. Electrostatic actuation of the parylene membrane using both DC and AC voltages was demonstrated and applied ...

Linearization of Electrostatically Actuated Surface Micromachined 2-D Optical Scanner

This paper presents an effective method of linearizing the electrostatic transfer characteristics of micromachined two–dimensional (2-D) scanners. The orthogonal scan angles of surface micromachined polysilicon scanner are controlled by using quadrant electrodes for electrostatic actuation. By using a pair of differential voltages over a bias voltage, we could improve the distortion of projecte...

Piezoelectrically Actuated Miniature Peristaltic Pump

Increasingly NASA experiments, instruments and applications are requiring pumps that are miniature and consume low power. To address this need, a piezoelectrically actuated pump is being developed. This pump employs a novel volume displacing mechanism using flexural traveling waves that act peristaltically eliminating the need for valves or physically moving parts. Finite element model was deve...

Modeling an Electrostatically Actuated MEMS Diaphragm Pump

The recent advent of microelectromechanical systems (MEMS) or micro-devices has generated excitement in many diverse fields. In the area of micro-fluidics liquid pumps are highly desirable for fluid transport and atomization. A recent and popular example of this is the inkjet, which self-aspirates ink from a reservoir and then transports it to a chamber for expulsion as a single droplet during ...

Paraffin Actuated Surface Micromachined Valves

A new, active, normally-open blocking microvalve that uses the thermal expansion of a sealed, thin paraffin patch for actuation has been fabricated and tested. The entire structure is batch-fabricated by surface micromachining the actuator and channel materials on top of a single substrate. The paraffin actuated microvalves are suitable for applications requiring many devices on a single die, l...
