Oscillating Diaphragms
The manufacture of miniature Stirling cycle cryocoolers, using standard micro-machining techniques and materials has been pursued by the authors [1]. A MEMS based cryocooler would allow integration of a cryogenic cooling system directly into a cryoelectronic device. Resonant bossed diaphragms were proposed as the means to sweep the working gas in the Stirling cooler, replacing the pistons and d...
متن کاملRadial Field Piezoelectric Diaphragms
A series of active piezoelectric diaphragms were fabricated and patterned with several geometrically defined Inter-Circulating Electrodes "ICE" and Interdigitated Ring Electrodes “IRE”. When a voltage potential is applied to the electrodes, the result is a radially distributed electric field that mechanically strains the piezoceramic along the Z-axis (perpendicular to the applied electric field...

متن کاملMicromachined Diaphragms with Integrated Actuation Coils
This paper presents a process for fabricating diaphragms, suitable for use in micromachined pumps within the field of micro-fluidics. To enable the actuation of a thick-film deposited magnetostrictive material, actuation coils are fabricated onto the non-chamber face of the diaphragms. These actuation coils are fabricated using a multilayer deposition approach compatible with micromachining pro...
متن کاملExperimental Design and Analysis of Bimorphs as Synthetic Jet Diaphragms
Synthetic jet actuators are promising Active Flow Control (AFC) devices which could lead to saving millions of dollars in fuel consumption each year. The Bimorph piezoelectric actuators are an attractive alternative to other type of actuators as active diaphragms and are the focus of this work. Among the properties of a Bimorph actuator, a number of geometrical and physical external factors may...
