An implantable device for sensing data includes a subcutaneous sensor configured to couple with an implant. The implantable device is operably configured to wirelessly and transcutaneously transmit data sensed by the subcutaneous sensor. The sensor may be powered wirelessly and transcutaneously. Transmission of data and/or power may be provided by ultrasound sound waves. The sensor may be in electrical communication with a piezoelectric transducer configured to receive the ultrasound sound waves.
