YPSILANTI – Integrated Sensing Systems announced that the U.S. Patent Office has granted it a utility patent (US 7,581,429) for Microfluidic Device and Method of Operation.
“The new patent and associated technology offers improved fluidic sensor and system designs and performance,” said Nader Najafi, ISSYS President and CEO. “The basic technology is already seeing use in industrial, chemical processing and biomedical devices, as well as fuel cell systems. This reinforces the other ISSYS’ patents on the design, packaging, fabrication, and application of microtube-based sensors, giving ISSYS comprehensive IP protection and offering a competitive barrier to market entry.”
According to Doug Sparks, Executive VP of ISSYS, this patent describes new designs and methods of compensating and controlling microfluidic devices using resonating micromachined tubes. These sensor chips are used by ISSYS to produce Coriolis mass flow meters, density and chemical concentration sensors, fuel quality, drug infusion systems, fuel cell concentration sensors, and other devices. It compliments other patents owned by ISSYS in the area of flow sensors and MEMS (MicroElectroMechanical Systems) devices. It provides new tube shapes and the electrode design enables improved performance. This improvement is important for critical applications like laboratory analysis, aviation fuel quality, fuel custody transfer and drug delivery systems.
ISSYS develops MEMS technologies for industrial, medical devices, microfluidic and scientific analytical sensing applications. Founded in 1995, ISSYS is one of the oldest independent MEMS companies in the US. ISSYS operates a full manufacturing under one roof, multi-million-dollar, state-of-the-art MEMS fabrication facility located near Ann Arbor, Michigan. An ISO 9001:2000 certified and ISO 13485:2003 (medical device manufacturing) qualified organization, ISSYS is a vertically integrated company dedicated to developing and manufacturing system-level products based on MEMS technology (MEMS Inside).
