a Exploded-view schematic illustration of the system. The upper inset shows a circuit diagram (upper-right). The lower inset is a photograph of the back side of the system. b Photograph of the device on the fingertip. c Experimental (E, symbols) and simulation (FEA, line) results of sensor voltages as a function of sample thicknesses with various moduli. d Dynamic measurements for modulus sensing on the human body. Left: Photographs of the forearm before (upper) and after (lower) lifting a dumbbell. Right: sensor voltages as a function of time during signal recording. Reproduced with permission42.
