Devices and techniques for interferential current stimulation

A device, comprising:

• a power source;
• a plurality of pairs of electrodes having a plurality of current paths, wherein each pair of electrodes is electrically connected to the power source, wherein each pair of electrodes is adapted to apply a current delivered from the power source in a respective current path of the plurality of current paths in order to stimulate a subcutaneous target within a subject, wherein the plurality of current paths have a plurality of first waveforms with a plurality of first frequencies, wherein the plurality of current paths overlap at an interference point having a second waveform with a second frequency, wherein the second waveform is result of a summation of electrical fields of the current delivered via each pair of electrodes;
• and
• a controller, wherein the controller is communicatively connected to the power source, wherein the controller is configured to send control signals in order to control the current delivered from the power source to each pair of electrodes in order to create a stimulation pattern for each electrode pair, wherein the controller is further configured to control the current delivered to each pair of electrodes such that each of the plurality of first frequencies is higher than the second frequency and such that the second waveform includes discrete interference pulses delivered with periods of quiescence between the interference pulses.
