Abstract:
Neural recording / stimulation devices to chronically record / stimulate biosignal, i.e., neuropotentials, in our bodies have been of great interest to scientists due to their potential benefits to diagnosis and treatment. Existing recording / stimulating system all comprise active components such as amplifier and microcontroller. One of the main concerns of using active components is the heat generation from the electronics could lead to heat trauma. Our work overcomes this disadvantage via fully-passive wireless biotelemetry. This unique wireless telemetry utilizes EM backscattering methods to record / stimulate biosignal. Their small size and ability to operate without any battery or energy harvester make them attractive and feasible for chronic recording / stimulation inside or on the body. We, for the first time, demonstrate wireless recorder having sensitivity of less than 60μVpp and stimulator having capability of more than 1 mA, all operating in a fully-passive manner.
