Flexibility demonstration of the SAN based sensor. a Comparison of sheet resistance as a function of bending time. b An enlarged figure of a; inset shows the detailed variation of sheet resistance of the SAN sensor from 490 to 550 s. c–f Characterization of sensors bending at different part of human body: c neck, d knee, e elbow, and f finger. Insets: photographs of the sensors attached to different part of human body
