radiofrequency (RF) (IMAGE)
Caption
The introduction of various gases, ions, nucleic acids, proteins, bacteria or pathogens, induces multiparametric changes in the 2D materials, which can be monitored and transduced by RF sensing circuits. Inset, depending on the device configurations (including but not limited to, resistor and varactor), the transducers connected with RF communicators aim to identify electrical signals such as resistance and/or capacitance variations and then transmit them to either the frequency shifts or changes in the full width at half maximum (FWHM).
