1. A system for locating an acoustic receiver-stimulator, comprising:

  • an implantable acoustic controller-transmitter comprising an array of acoustic transducers configured to transmit focused acoustic energy to a tissue location;

    at least one implantable acoustic receiver-stimulator adapted to receive the focused acoustic energy and convert the focused acoustic energy into electrical energy;

    wherein the receiver-stimulator further comprises two electrodes configured to be in electrical connection with tissue and to deliver the electrical energy to the tissue;

    wherein the controller-transmitter is configured to detect the delivered electrical energy to determine whether the receiver-stimulator is present at the tissue location; and

    wherein the controller-transmitter is further configured to adjust the transducer array to transmit focused acoustic energy to the tissue location associated with the detected electrical energy.
