The assistive wearable BrainPatch’s neurotechnology for an individual’s mental well-being

Results

The BrainPatch Headphone Stimulators (https://www.brainpatch.ai/) are a combination of wireless headphones and wireless non-invasive transcutaneous auricular vagus nerve stimulators (micropolarization). The stimulation zone included the mastoid area where the auricular branch of the vagus nerve exits the cranium by passing through the tympanomastoid fissure between the mastoid process and the tympanic part of the temporal bone, and divides into two branches (first one joins the posterior auricular nerve, the other spreads to the skin of the auricle area of the ear and to the posterior part of the ear canal). The BrainPatch VNS device proposes a personalized approach to stimulating both the right and left vagus nerve. A BrainPatch application for iOS or Android operating systems is using for randomisation and for delivery of assigned protocols to the BrainPatch device as well as for collection of data on the execution of the protocol. The electrical stimulator (electrodes built into the headphones) consists of an analog-to-digital converter and a circuit that allows any signal to be delivered up to +/- 1.5 mA and up to ~ +/- 30 V to the electrodes. For the safety of stimulation, in addition to restrictions in the application, in the electronics itself there are 2 mA limiters in both directions. For stress-related and mental disorders treatment an application combines pleasant meditative classical music and a slow bi-polar wave (0.1-0.2 Hz, strength of current 0.25-1.5 mA, current frequency - 20-30 Hz, stimulation duration 5 min) of electrical stimulation, which produces a relaxing effect.
