Devices for nerve stimulation

Abstract

Systems, devices and methods are provided for stimulating one or more nerves within a user. A system comprises a stimulator comprising an electrode configured for contacting the outer skin surface and an energy source coupled to the stimulator and configured to generate a plurality of positive voltage waves. The stimulator further comprises a bridge circuit configured to convert the positive voltage waves into alternating positive and negative voltage waves. The stimulator transmits the alternating positive and negative voltage waves transcutaneously from the electrode through the outer skin surface of the user to a selected nerve in the user adjacent to, or near, the target location. This allows the energy source to drive a full AC sine wave to the electrode using a single positive voltage rail, which reduces the complexity of the overall circuit, thereby reducing its overall size or footprint within the stimulation and its manufacturing cost.
