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

Modern portable devices are the result of great progress in miniaturization and wireless communications. Now that these devices can be made even smaller and lighter without loss of functionality, it's likely that a great part of next-generation electronics will revolve around wearable technology. However, for wearables to truly transcend portables, we will need to rethink the way in which devices communicate with each other as "wireless body area networks" (or WBANs). The usual approach of using an antenna to radiate signals into the surrounding area while hoping to reach a receiver won't cut it for wearables. This method of transmission not only demands a lot of energy but can also be unsafe from a cybersecurity standpoint. Moreover, the human body itself also constitutes a large obstacle because it absorbs electromagnetic radiation and blocks signals.
