All in your head: Exploring human-body communications with binaural hearing aids

Wearable technology seems all poised to take over next-generation electronics, yet most wireless communication techniques are not up to the task. To tackle this issue, scientists have delved deep into human-body communications, in which human tissue is used as the transmission medium for electromagnetic signals. Their findings pave the way to more efficient and safer head-worn devices, such as binaural hearing aids and earphones.
