Fig. 10

a Implementation of a 6 × 3 array of SiC humidity sensors, (b) demonstration of the change in response of the printed SiC humidity sensor array with contact from human hand with and without a glove (barrier), (c) illustrating depicting the change in response where the image at O seconds corresponds to the sensor arrays response at rest. The second image reflects sensor behavior at 540 s where sensors that are in contact with the uncovered hand detect a change in humidity. The last iamge corresponds to the sensor arrays response at 950 s where sensors that responded to change in humidity show a very small residual resistance value after desorption.
