DRY ELECTRODES FOR TRANSCUTANEOUS NERVE STIMULATION
First Claim
1. A dry electrode for transcutaneous electrical stimulation, the dry electrode comprising:
- a conductive backing layer; and
a skin contact layer disposed on the conductive backing layer, the skin contact layer comprising a polymer, plastic, or rubber material, and a conductive filler material dispersed substantially evenly throughout the polymer, plastic, or rubber material, wherein the skin contact layer has a skin facing surface that is not coated with a hydrogel or liquid.

Abstract
Disclosed herein are systems, devices, and methods for peripheral nerve stimulation, particularly for treating tremor. The nerve stimulation may be accomplished by a wearable nerve stimulation device, such as a band configured to be worn on the wrist or other body part. The device can accomplish targeted nerve stimulation using circumferentially spaced electrodes. In some embodiments, the device may use only the same number of electrodes as the number of nerves that are to be stimulated. A biphasic charge-balanced waveform may be used to selectively stimulate a nerve near one of the activated electrodes but not to stimulate the nerve near the other activated electrode. The device may use dry electrodes for long-term, repeated use. The dry electrodes may include a conductive base layer and a polymeric, plastic or rubber skin contact layer comprising a conductive filler. The filler may be a powder, fiber, conductive coating, etc.
