In this paper, we introduce a wireless power transfer (WPT) scheme using flexible coils and electronic circuits for wearable devices and future flexible devices. Recently, a flexible wearable market is rapidly growing and much effort is made to transform rigid devices into flexible devices. The reason is to provide the comfortable user environment. To realize the flexible devices, electronic circuits must be flexible. Therefore, we designed the voltage-controlled oscillator to analyze the oscillation characteristics with the bending radius. In this paper, we will discuss about a WPT scheme to deliver power to the VCO and designing process of the VCO by considering the effect of thin silicon substrate. To design the VCO, we used SK-Hynix 350 nm CMOS process.
