Body Area Network (BAN) Connectivity

Body Area Network (BAN) connectivity uses ultra-low-power electric field (E-field) communication to create secure wireless links between wearable devices that are physically in contact with or very close to the human body. The signals are confined to the body surface through capacitive coupling, creating a communication channel that extends only a few centimeters from the skin. This physical confinement provides inherent security, as signals cannot be intercepted from a distance like traditional radio frequency communications.

The ultra-low-power operation enables battery-powered wearables to communicate continuously without significantly impacting battery life. The technology enables multiple wearable devices—such as smartwatches, fitness trackers, medical sensors, and hearing aids—to form a secure network around the body, sharing data and coordinating functions. Applications include health monitoring where multiple sensors share data, hearing aid systems where left and right devices coordinate, and fitness tracking where multiple devices work together. The body-confined communication ensures privacy and security for sensitive health and biometric data, while the low power consumption enables long-lasting wearable devices.
