Abstract The WIMS center, funded by the U.S. National Science Foundation and by 20 companies, is researching wirelessly connected microsystems for environmental monitoring and biomedical applications. This multi-disciplinary work, focused on two test beds, involves 40 faculty and 100 doctoral researchers. One testbed is a family of neural prostheses aimed at treating disorders such as deafness, paralysis, epilepsy, and Parkinson's disease. Michigan has pioneered this technology, which is now the focus for intense efforts worldwide. During the past year, the center realized the first implantable multi-channel microsystem for multipoint cortical recording.
New research is underway for the treatment of Parkinson's disease and epilepsy. An analog front-end chip comprised of amplifiers, filters, and an ADC for processing and digitizing neural signals is being designed. All these components are being optimized for processing neural signals. Circuitry for neural stimulation will also be implemented on the IC. A prototype is being developed for 0.18um CMOS. A collaboration with Professor Daryl Kipke's Neural Engineering Llaboratory at Michigan's Biomedical Engineering Department is guiding the specifications of the prototype.
