Active Digital Aura (ADA) Body Coupled Communication


ADA is based on the concept of capacitive body coupled-communication (BCC). When close to a user’s body, an ADA transceiver generates a “personal communication aura” – a low-energy electric field across the surface of the body. Information is encoded in variations in this aura, which can be detected by a receiver in a second ADA-enabled device. ADA is an extremely safe and clean technology. An ADA electric field is orders of magnitudes weaker than those from mobile phone. Sending power is less than 1 mW and, unlike with RF technologies such as Bluetooth or Wi-Fi, none of this energy is absorbed by the human body.
