Wearable Battery‐Powered Transmitter and Receiver for Path Loss Measurement of Capacitive HBC Channel

open access: yesInternational Journal of Circuit Theory and Applications, EarlyView.
This paper presents the design of a wearable battery‐powered capacitive coupling‐human body communication (CC‐HBC) transmitter–receiver allowing a realistic power path loss estimation. The influence on the power path loss of the inter‐electrode distance, body constitution, posture, electrode‐skin contact pressure, and transmission frequency (21 and 42 ...
