Abstract: A sensing apparatus and method allows a patient to control an object by asserting a motor unit action potential. An electromyogram sensor is configured to be placed at a selected location on the patient and to sense a motor unit action potential from the patient. The electromyogram sensor is also configured to generate an EMG signal representative of the motor unit action potential. A personal area network transmitting device that is responsive to the EMG signal is configured to generate a wireless signal that corresponds to the EMG signal. A personal area network receiving device is configured to receive the wireless signal and to convert the wireless signal into an electrical signal. A processor is configured to receive the electrical signal and to generate at least one control signal that has a value corresponding to a state of the electrical signal.
