A new multi-device wireless power transfer scheme that reduces the overall charging time is presented. The proposed scheme employs the intermediated energy storage (IES) circuit which consists of a constant power driving circuit and a super-capacitor. By utilizing the characteristic of high power density of the super-capacitor, the receiver can receive and(More)
This paper proposes IoT device system supporting the self-powered generation and backscatter communication by using Wi-Fi signal. We design and implement the data link sequence and communication system. The proposed IoT device system transfers data by backscatter-modulating the power level of the ambient Wi-Fi packets, instead of communicating Wi-Fi(More)
