Abstract: 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.

Abstract: A wrist or finger mounted wearable device and method for determining a state or activity level of the autonomic nervous system, such as the respiratory rate or activity of the vagus nerve. The wearable device having at least a pair of electrocardiograms (ECG) measurement electrode pads configured to perform hand-to-hand ECG measurements. The device or method including monitoring of the pair of ECG measurement pads at a first time period to arrive at a first reading of hand-to-hand ECG, and at a second time period to arrive at a second reading of hand-to-hand ECG. The device or method analyzing the first and second readings of ECG to arrive at various indications of the state of a user.

Abstract: Systems and methods here include measuring and analyzing biosignals. Some embodiments include measuring a magnetic bio signal using a coiled wire system, sending the measured bio signal to a computer for processing, receiving the measured bio signal and processing the bio signal, choosing a stimulation signal, based on the received measured bio signal, sending the chosen stimulation signal to a stimulation device, and administering the stimulation signal with the stimulation device.
