Abstract [en]

The application of using the capacitively coupled body area network (BAN) to build up the communication between a mobile phone and a wearable device is presented in this letter. The proposed system operates at 26 MHz, the capacitively coupled BAN channel is discussed, and electrode designs for wearable devices and smartphones are proposed. The transmission coefficient of the BAN channel is increased by 6.5 dB in the wearable device and 15 dB in the mobile phone with our optimized design of electrodes. Another 10 dB increment is also achieved by adding a parallel resonant circuit.
