Abstract:
1. A glove for measuring electromyography (EMG) signals in a hand comprising: a glove body; a plurality of EMG electrodes disposed at predetermined locations on an inner surface of said glove body and configured to sense a magnitude of a plurality of EMG signals over a period of time, wherein said EMG electrodes are disposed at locations targeted to specific muscle locations on a hand of a user when said glove body is worn; a data acquisition circuit coupled to said plurality of EMG electrodes and configured to receive at least one of said plurality of EMG signals and to generate an output proportional to said magnitude of said at least one of said plurality of EMG signals sensed by at least one of said plurality of EMG electrodes; and a user feedback module located on an external surface of said glove body and configured to provide a representation of said output of said data acquisition circuit, wherein said plurality of EMG electrodes comprises at least two pairs of EMG electrodes, each pair coupled to two inputs of a single differential amplifier, such that a first EMG electrode of one of said pairs of EMG electrodes is electrically coupled to said single differential amplifier and comprises an active electrode and senses EMG signals from a muscle of the hand, and a second EMG electrode of said pair of EMG electrodes is coupled to said single differential amplifier and comprises a reference electrode which senses EMG signals from an area of a bone of the hand.
