Abstract

Emerging appli cations in brain–machine interface systems require high-resolution, chronic multisite cortical record- ings, which cannot be obtained with existing technologies due to high power consum ption, high invasiveness, or inability to transmit data wirelessly. In this paper, we describe a microsystem based on electrocorticography (ECoG) that overcomes these dif- ficulties, enabli ng chronic recording and wireless transmission of neural signals from the surface of the cerebral cortex. The
