Three micro-fabricated shell processes are developed in this work, each tailored to a specific application. The first is a two-wafer molding process used to fabricate polysilicon shell suspensions that are very light and stiff. The second is a single crystal silicon...

A method for performing interventional surgery has been developed. Transvascular delivery of therapeutic and diagnostic agents into perivascular space is desirable for various cardiovascular treatments and applications. The dosing of perivascular space requires the perpendicular actuation of a microneedle to slide through the layers...

This work describes the development of low-power bubble-actuated planar micro gate valves. The work includes the design of the gate valve, the development of electrolysis bubbles as a low power actuator, and a novel fabrication procedure that allows these valves to be integrated with other planar fluidic devices and controlling circuitry. The operation of the valves is demonstrated and valve performance is measured in terms of leakage, power consumption, and cycle time.

The low-power, bubble-actuated, planar micro gate valves consist of a silicon gate that is thrust across a...

2001
Vibratory micromachined gyroscopes typically exhibit certain undesirable behaviors that impede the angular rate measurement, such as nonlinearity, cross-axis sensitivity, scale factor offset, and quadrature error. These errors have sources in both the mechanical and electrical ...
