Abstract
A three-way (3-way) Micro-Electro-Mechanical Systems (MEMS)-based micro-valve device and method of fabrication for the implementation of a three-way MEMS-based micro-valve that uses a multicity of piezoelectric actuators. The 3-way has a wide range of applications including medical, industrial control, aerospace, automotive, consumer electronics and products, as well as any application(s) requiring the use of three-way micro-valves for the control of fluids. The three-way microvalve device and method of fabrication can be tailored to the requirements of a wide range of applications and fluid types. The microvalve can be used to control fluids at high pressures and provides for low flow resistances when the microvalve is open and has low leakage when closed.
