NIST grant to fund wireless implant research

The National Institute of Standards and Technology’s Advanced Technology Program has awarded $1.98 million to Integrated Sensing Systems (ISSYS) to develop wireless, batteryless microfabricated pressure sensors. ISSYS is working on sensors that can provide continuous monitoring of biologic fluid pressures while implanted in the body. Initially, the sensors will be used for hydrocephalus and glaucoma.

The Ypsilanti, MI-based firm produces a pressure sensor the size of a grain of rice, and it intends to extend that product’s capabilities to a single, self-contained unit that will be powered and read by an external radio-frequency transceiver. The handheld transceiver will be able to detect sensor readings from up to six inches away. The University of Michigan’s Kellogg Eye Center and the Cleveland Clinic Foundation have agreed to test the products. ISSYS estimates that the devices can save more than $1.5 billion annually in medical testing and treatment.
