Conventional chemiresistive sensing experiments employ two or four point probe conductance measurement methods, which may damage thin film sensing materials. In the case of monolayer graphene sensors, the possibility of such damage is of particular concern. In recent research, the authors have applied a new non-contact (eddy current) sensing method to perform oxygen sensing experiments on pristine monolayer graphene. In addition to avoiding contact damage to the sensor surface, the testing process is streamlined and sample throughput is accelerated, by avoiding the need to design and deposit electrodes. Test results to date indicate that device sensitivity (sheet conductance) is significantly increased, as compared to published results using conductance probes. Repeatability is improved and sensor recovery time is reduced, using UV illumination without thermal annealing or ultrahigh vacuum treatments.
