From Sensing Mechanisms to System Co-Design: Graphene-Based Sensors and Readout Circuits. [PDF]
Adv Sci (Weinh)This review establishes a unified PS–EQ–RF framework linking graphene sensing mechanisms, native electrical outputs, and output‐specific readout circuits. Voltage‐, current‐, resistance‐, and capacitance‐type sensing systems are systematically classified to guide architecture selection, low‐noise design, system co‐design, and practical integration ...

Optimal Coupling for Capacitive Wireless Power Transfer with One Repeater
2022 52nd European Microwave Conference (EuMC), 2022 Abstract: In order to extend the range of capacitive wireless power transfer, an electric field repeater between transmitter and receiver can be applied. In this work, a network formalism is adopted to analytically describe and maximize the system efficiency of a repeater setup. The resonator components, resistive losses, load and supply impedances are
