Abstract: A topical nerve activation patch includes electronic circuitry embedded in the patch and electronic circuitry configured to generate an output voltage applied to electrodes. The patch further includes a controller configured to generate a treatment comprising a plurality of activation pulses that form the output voltage, the controller comprising a first real time clock and an oscillator, the treatment comprising electrical stimuli applied to the user via the electrodes. The patch further includes a charge measurement circuit configured to measure an amount of charge applied to the user from the electrical stimuli and a communication link configured to communicate with a remote activation device, the remote activation device comprising a second real time clock. The controller is configured to generate the activation pulses by measuring time intervals using the oscillator and using the second real time clock and the measured time intervals to determine activation times for the activation pulses.

Abstract: One example provides a nerve stimulation treatment using electrodes coupled to a user. Examples determine a target charge level and output a series of pulses from the electrodes. For each pulse outputted, examples measure a charge value of the pulse and compare the charge value to the target charge level. If the charge value is greater than the target charge level, examples reduce a strength level of a subsequent outputted pulse. If the charge value is less than the target charge level, examples increase the strength level of a subsequent outputted pulse.
