Devices and methods for the non-invasive transcutaneous neurostimulation of the neck and ear vagus nerves via electrical, magnetic and haptic stimulation
A wearable device and method for multimodal stimulation of the vagus nerve having a pair of ear pieces, which are placed at least partially within the concha of an individual. Each ear piece has at least on electric stimulator which provides electric current to the ear of the individual. The wearable device also has a connection which provides stimulation instructions to the stimulators. The method for multimodal simulation also includes iterative biometric measurement and stimulation.
