LITHOGRAPHY INDEPENDENT MICROFLUIDIC CHECK VALVE
The technology consists of a microfluidic check valve that offers outstanding performance while providing an easy manufacturing technique, independence from lithographic methods, size scalability and an unique set of system properties
The check valve is a very basic element of microfluidic chips. It acts as a simple flow director like an electric diode but for fluidics and gases. It is used, and it will be used in a vast number of circuits needed in all types of chips expected to evolve in the uprising market of microfluidics.
A microfluidic check valve that offers outstanding performance while providing an easy manufacturing technique, independence from lithographic methods, size scalability and a unique set of system properties. No additional elastomer layer has to be added to the chip. The valve consists of a membranous hinge serving as the closing valve element made of an elastic photopolymer which is only localized in the housing of the valve, nowhere else on the chip.
