System and method for power-efficient transmission of EMG data

The system for displaying muscle force data includes a wearable patch and a remote visual display. The wearable patch carries electrodes suitable for sensing electromyographic signals on the skin of the patient. The patch carries circuitry which converts the detected electromyographic signal to a digital output which can be transmitted to the remote visual display. The circuitry relies on filtering to produce a usable digital signal at very low power consumption. The transmitted signal can be used to drive a variety of visual displays, including a conventional hand-held personal communicators and entertainment devices which had been programmed to suitably process the visual display.
