Autonomous wireless sensors for biomedical monitoring are becoming technology plausible. Though they have the potential to dramatically improve quality of life for patients suffering from a wide variety of illnesses an injuries, the power consumption requirements pose several remaining challenges. These include low-noise signal acquisition, local processing, and wireless communication.
In this talk, I will describe low-power analog circuits that have been developed to address the signal acquisition and processing problems for neural recording systems. I will also present preliminary results from integrated recording systems and discuss future research.
