Self-powered wireless smart patch for healthcare monitoring

In this work, a self-powered wireless smart patch is present to realize wearable wireless transmission utilized for monitoring temperature and motion status without any extra power supply. A novel wireless transmission mechanism based on electrostatic induction is presented showing near field transmission efficiency of 26.6% with distance of 1 cm. Steady fabric based electrodes and stretchable sandwich structural Ag NW electrodes are developed respectively to satisfy the specific demands of convenience and extensive applicability.155
