Abstract
A wearable electronic device includes an electrode array for transdermal stimulation of a sensory nerve that itself innervates a body part distal to a worn location of the wearable electronic device. The transdermal stimulation is configured to induce an electrical current or voltage that evokes a sensory impression at an area innervated by the sensory nerve, not at the stimulated sensory nerve itself. In one implementation, the wearable electronic device takes a finger ring form factor worn on a proximal phalanx of an index finger. In this configuration, the wearable electronic device can stimulate a portion of a branch of the median nerve extending through the index finger. Upon stimulation of the median nerve, a user wearing the finger ring may perceive pressure applied to the user's fingertip.
