1. An electronic device implantable in the muscle of an animal, comprising:
a near linear radio frequency device antenna adapted and configured to i) transmit an RF signal, and ii) receive wireless power via electric field coupling from a broad-beam external source;
a digital controller transmitting data by said device antenna;
a pair of spaced-apart electrodes each adapted and configured to be in electrical communication with a muscle of the animal and each providing an electrical signal to said digital controller corresponding to the electrical activity of the muscle;
an internal source of electrical power including an internal storage device to power said digital controller; and
a biocompatible housing encasing said device antenna, said controller, and said internal source, said biocompatible housing encasing the pair of spaced-apart electrodes;
wherein the electrodes are configured to be placed in close proximity to a nerve and thus detect electromyogram (EMG) signals at a source of the EMG signals and the digital controller is configured to process said EMG signals.
