Disclosed herein are systems and methods for sensor systems. In one embodiment, a system may include an implantable component and an external component. The implantable component may comprise a housing and an electrode array configured to receive a plurality of biopotential signals. The housing may comprise a wireless power receiver and a wireless data transmitter to transmit representations of the biopotential signals. The external component may comprise a wireless data receiver configured to receive the plurality of digital representations of the biopotential signals and a wireless power transmitter configured to provide power to the internal component. A shielding component may separate the wireless power transmitter from the wireless data receiver. An interface may be configured to communicate with a prosthesis and configured to cause the prosthesis to implement a voluntary motion based on the plurality of digital presentations of the biopotential signals.
