Abstract
An electrical stimulation system includes a sheath that includes conductive points that are operative to facilitate electrical stimulation to a bodily portion of a user. Drive-sense circuits (DSCs) generate electrical stimulation signals based on reference signals and provide those electrical stimulation signals via electrodes to the conductive points of the sheath. The electrical stimulation signal is coupled into respective locations of the bodily portion of the user that are in proximity to or in contact with the conductive points of the sheath. In addition, the DSCs sense, via the conductive points of the sheath and via the electrodes, changes of the electrical stimulation signals based on coupling of them into the respective locations of the bodily portion of the user. The DSCs provide digital signals that are representative of the changes of the electrical stimulation signals to one or more processing modules that includes and/or is coupled to memory.
