a, Standard auxetic design laser cut from the FSF. b, The actual design of the auxetic includes holes to route the electrodes (shown in red and blue), and slots allow the square, sensing island to rotate, enhancing the stretchability of the sensor array. c, Close-up of the fabricated array showing the conductive thread electrodes before insulation. d, A fully fabricated 10 × 10 array with an auxetic design. e, Auxetic patterning allows the sensor array to be folded, crushed and stretched easily with no damage. f, The array can also be stretched in multiple directions (see Supplementary Video 2).
