Moreover, natural wrinkle structures allow the surface to switch dynamically and reversibly from flat to rough in response to specific stimuli. Artificial wrinkle structures have been developed for applications such as optical devices, mechanical sensors, and microfluidic devices. However, chemical molecule\u2010triggered flexible sensors based on dynamic surface wrinkling have not been demonstrated. Inspired by human skin wrinkling, herein, a volatile organic compound (VOC)\u2010responsive flexible sensor with a switchable dual\u2010signal response (transparency and resistance) is achieved based on a multilayered Ag nanowire (AgNW)\/SiO\n                    <jats:italic>\n                      <jats:sub>x<\/jats:sub>\n                    <\/jats:italic>\n                    \/polydimethylsiloxane (PDMS) film. Wrinkle structures can form dynamically in response to VOC vapors (such as ethanol, toluene, acetone, formaldehyde, and methanol) due to the instability of the multilayer induced by their different swelling capabilities. By controlling the modulus of PDMS and the thickness of the SiO\n                    <jats:italic>\n                      <jats:sub>x<\/jats:sub>\n                    <\/jats:italic>\n                    layer, tunable sensitivities in resistance and transparency of the device are achieved. Additionally, the proximity mechanism of the solubility parameter is proposed, which explains the high selectivity of the device toward ethanol vapor compared with that of other VOCs well. This stimuli\u2010responsive sensor exhibits the dynamic visual feedback and the quantitative electrical signal, which provide a novel approach for developing smart flexible electronics.\n                  <\/jats:p>","DOI":"10.1002\/smll.201900216","type":"journal-article","created":{"date-parts":[[2019,3,28]],"date-time":"2019-03-28T04:12:41Z","timestamp":1553746361000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":53,"title":["Bioinspired Flexible Volatile Organic Compounds Sensor Based on Dynamic Surface Wrinkling with Dual\u2010Signal Response"],"prefix":"10.1002","volume":"15","author":[{"given":"Chunyan","family":"Qu","sequence":"first","affiliation":[{"name":"i\u2010Lab Key Laboratory of Multifunctional Nanomaterials and Smart Systems Suzhou Institute of Nano\u2010Tech and Nano\u2010Bionics (SINANO) Chinese Academy of Sciences (CAS)  398 Ruoshui Road Suzhou Jiangsu 215123 P.
