Abstract

This paper reports the design, modeling, fabrication and measurement of passive microvalves applicable to glaucoma implants. The proposed microvalves consisted of microchannels and chambers. The microchannels had a fixed fluidic resistance and generated a pressure difference. The chamber was located in the middle of the microchannels and acted as a buffer preventing an abrupt pressure change from an external variation of the fluid flow. To find optimum design parameters, six kinds of the microvalves were fabricated and experimented.
