a Temperature response profiles of the ATACS with active control and passive control. The top images are the digital image of the ATACS with respect to time. The scale bar is 2 mm. b Optical images of the ATACS with a feedback control system under cooling with ice. A graph of the feedback control system operation under temperature drop of the ATACS. The scale bar is 5 mm. c Digital image of RGB colored ATACS with various curvatures. The scale bar is 5 mm. d Electrical resistance variation of the ATACS during a long-term cyclic test over 1000 times bending. e ATACS without degradation in color performance after 1000 cycles of repeated bending. The scale bar is 1 mm.
