Single transducer-based sensors have limitations of sensitivity and detection range. To enhance the sensitivity and range of detection here, a multi-transducer-based sensing array is designed for humidity sensing applications. Two-dimensional (2D) transition metal dichalcogenide (TMDC) namely MoSe2 nano-flakes and an organic semiconducting polymer polyvinyl alcohol (PVOH) are employed as active layers for two different sensors on a single polyethylene terephthalate (PET) substrate. Here, MoSe2 nano-flakes are highly responsive towards the low relative humidity (RH) region below 50% RH, while the PVOH is responsive to high humidity levels above 50% RH. The two sensors are combined in series as sensor array, which are capable to detect linear humidity response from all range of RH. Screen-printing and spin coating techniques are utilized for fabrication of inter digital electrodes (IDEs) and active layers, respectively. The impedance responses of individual as well as sensor array are recorded at 1 kHz frequency to analyze the fabricated sensor, and COMSOL Multiphysics platform is used for designing and verification of experimental results. The fabricated sensor is capable to detect a wide range from 0 to 100% RH, with a response time (Tres) of 0.6 s and recovery time (Trec) of 0.9 s with a very high sensitivity of 50 kΩ/RH. This approach can resolve the limitations of sensitivity, detection range, and response time faced in single transducer-based sensors.
