Abstract

The present disclosure provides a wearable device for electro-quasistatic human body communication and a method thereof. The wearable device includes sensors, a first set of conductors, and a second set of conductors. The wearable device includes a processor to generate a data packet for transmission to at least one computing device of a user. The processor applies an excitation voltage between the first set of conductors and the second set of conductors. As a result, the first set of conductors generates electro-quasistatic (EQS) signals and the second set of conductors applies the electro-quasistatic (EQS) signals to the user's body, thereby enabling human-body communication (HBC) for transmission of the data packet between the wearable device and the at least one computing device. Furthermore, the processor triggers a feedback module to generate a notification in response to the successful transmission of the data packet to the at least one computing device.
