Sensitive and Stretchable Strain Sensors Based on Silver Nanowires Network

In this paper, we report on mechanical and electrical properties of the stretchable strain sensor based on two-dimensional network of silver nanowires embedded between bio-compatible polydimethylsiloxane films. Our strain sensor shows a quasi-linear response of resistance change with respect to stretching up to 15%. Dynamic stability and durability of the strain sensor are investigated through cyclic stretching test (1,000 times). We also demonstrate sensitivity of our strain sensor under the pulse-type stresses with arbitrary intensities.
