A smart poultice with reconfigurable sensor array for wearable cardiac healthcare

A smart poultice with reconfigurable sensor array is implemented by using planar fashionable circuit board (P-FCB) technology for wearable cardiac healthcare. It contains 1) 25-electrode array either for vital signal sensing or for external data communication, 2) a thin flexible battery, 3) a fabric inductor, and 4) a fabric circuit board on which a low power silicon chip is directly integrated. Start/stop operation of the smart poultice is realized by inductive-coupled remote controller with 8b ID verification function and external low power data transaction is achieved by using duty cycled body channel communication.
