Integrated Sensing Systems Inc. (ISSYS) has been granted a U.S. Patent (US 7,628,082), titled “Microfluidic Device and Microtube Therefore,” for its resonating micromachined tubes. The devices are designed to provide improved sensing performance.

The sensor chips are used by ISSYS to produce Coriolis mass flow meters, density and chemical concentration sensors, drug infusion systems, fuel quality and fuel cell concentration sensors, and other devices. According to ISSYS, the patent complements its other patents in the area of flow sensors and MEMS (MicroElectroMechanical Systems) devices. It provides new tube shapes and electrode design to improve performance. The improvement is important for critical applications like laboratory analysis, intrinsically safe aviation fuel quality, custody-transfer markets, and in new drug delivery systems.

The new patent for the microtube design and associated technology offers improved fluidic sensor and system designs and performance. The basic technology is currently applied in industrial and chemical processing, fuel transfer, biopharmaceutical devices, as well as fuel cell systems.
