A miniature power-efficient bidirectional telemetric platform for in-vivo acquisition of electrophysiological signals

Summary form only given, as follows. The need for in vivo wireless acquisition of biological signals is emerging in various medical fields. Electrophysiological applications including recording gastric electrical activity (GEA), electrocorticography (ECoG), and transcranical motor evoked potentials (TcMEP) require physically miniaturized devices with low power consumption and capability of implantation. We have developed three telemetric systems for GEA, ECoG and TcMEP applications based on a common transceiver platform.
