A device system and method for wirelessly communicating through tissue is provided. The device system comprises an implanted device with an array of antennas aligned with a tandem device with an array of antennas outside of the body. The two devices wirelessly communicate in a bi-directional manner. The implanted device can act as a physiological sensor and stimulator, and the external device can act as a controller and relay. Such configurations allow for a range of uses within research and clinical settings.
