| Abstract |
This paper introduces a lightweight wearable heart rate measurement system based on wireless power transfer for bio-signal detection. The use of the wireless power transfer method can solve the problems of bulkiness and inconvenience due to the detachment for battery recharging from the conventional battery based system. Furthermore, a new control method for wireless power transfer system is proposed to minimize waste of power during near-field operation and achieve optimal power consumption by adaptively control the receiver input. |
