With the growing aging society, extending healthy life expectancy has been attracting attention. Small devices using IoT and wireless technologies are expected to have effect on self-health management. However, batteries and power cables cause problems such as the restriction on human motion or the devices’ size. Therefore, wireless power transmission (WPT) addresses these problems and use of WPT may help with improving daily health care management. In this paper, we propose a WPT system between mobile devices and a sensor on the fingertip by using Near Field Communication (NFC). The proposed system can transfer enough power for IoT sensors.
