a Images showing the skin-like characteristics of the intrinsically stretchable organic transistor-based image sensor arrays. b Dark current of stretchable organic X-ray image sensors in a 10 × 10-pixel array. The applied VDS and VG are −5 V and 0.5 V, respectively. c Map of the X-ray response for the word “Hi” at a low dose rate down to 24.34 nGyair s−1. d Optical microscope (upper) and X-ray images (bottom) of a molybdenum plate patterned with alternating fringes of different line pairs (lp) (The scanning spacing is 5 µm). e MTF of the intrinsically stretchable organic X-ray image sensor. f Photograph (upper) and corresponding X-ray image (bottom) of the steel sheet with a round hole using the short-channel stretchable organic transistor (2 μm) (The scanning spacing is 200 µm). g Photograph (upper) and corresponding X-ray image (bottom) of an integrated circuit device (The scanning spacing is 15 µm). h Photograph, and corresponding X-ray image of an encapsulated metallic spring (The scanning spacing is 20 µm). The scale bar is 2 mm.
