Figure 4. Image reconstructed through the accumulative effect of short-term ion dynamics. a) Schematic of image reconstructing process through a set of images with random noises added on the original image by the human brain. b) Different channel current changes induced by the encoded pulse train of spatiotemporal information. c) A series of pictures with random noise in contrast with the original image was sent to the array continuously, in which the array consisted of ion-modulated memtransistors. d) Experimental results of images reconstructed through the short-term ion dynamics, where the drain current at the end of stimuli represents the value for each pixel.
