“…The tabulated RF biosensors are based on three kinds of passive RF devices and circuits-transmission line [66], capacitor [67], and resonator [68]. First, the rGO-groundsignal-ground (GSG) electrode-based RF sensing scheme was validated with TL parameters, i.e., resistance (R), inductance (L), conductance (G), and capacitance (C), as sensing parameters with different glucose concentrations (Figure 5a) using the measured scatteringparameter (S-parameter).…”

In the past decade, graphene has been widely researched to improve or overcome the performance of conventional radio-frequency (RF) nanodevices and circuits. In recent years, novel RF bio and gas sensors based on graphene and its derivatives, graphene oxide (GO) and reduced graphene oxide (rGO), have emerged as new RF sensing platforms using a wireless remote system. Although the sensing schemes are still immature, this review focuses on the recent trends and advances of graphene and GO (rGO)-based RF bio and gas sensors for a real-time and continuous wireless health care system.

In this paper, the advances in radio-frequency (RF)/microwave biosensors based on graphene nanomaterials including graphene, graphene oxide (GO), and reduced graphene oxide (rGO) are reviewed. From a few frontier studies, recently developed graphene nanomaterials-based RF/microwave biosensors are examined in-depth and discussed. Finally, the prospects and challenges of the next-generation RF/microwave biosensors for wireless biomedical applications are proposed.

“…Several types of microwave-based sensor device (Iramnaaz et al 2011;Wichaidit et al 2001) that exhibit high sensitivity to the changes of dielectric properties of the sample have been proposed. Thus, the detection signal sends signal-to-noise ratio and reliability has always been very low.…”
