Abstract

An apparatus for sensing biological signals from an animal. The implanted apparatus includes at least one implantable electrode pair that is connected to a twisted pair of insulated conductors. The electrode pair is disposed at a first set of locations to sense biological signals. The twisted pair of insulated conductors is connected to an instrumentation amplifier via a passive network of filters. The amplifier amplifies the filtered biological signal from the electrode pair to provide an amplified differential signal. The amplifier has an internal voltage reference. Additionally, an energy source powers the apparatus without being connected to mains or an isolation transformer of medical equipment. A signal analysis module analyzes amplified differential signals to obtain at least one physiological parameter. The apparatus may also comprise a signal presentation module to display amplified signals and physiological parameters associated with the signal.
