Abstract
An electronic stimulating device is disclosed, with the stimulating device particularly illustrated being a transcutaneous nerve stimulating (TENS) device for effecting suppression of pain by nerve fiber stimulation. Biphasic constant current output pulses are applied to a user through electrode pairs noninvasively positioned at the skin of the user. Microprocessor generated control pulses control generation of the biphasic output pulses at a biphasic output stage associated with each electrode pair, and the generated biphasic output pulses are capacitively coupled from each output stage which also includes a bleeder network for effecting capacitor discharge. Stimulation may be continuously applied at a level selected by the user or may be applied in timed varying intensities the maximum level of which is selectable, and displays of intensity and sensed faults, including low battery voltage, are also provided.
