Here, we demonstrated a highly stretchable pressure sensor using silver nanowires (AgNWs) and photo-patternable polyurethane acrylate (PUA). In particular, the characteristics of the pressure sensors could be moderately controlled through a micro-patterned hole structure in the PUA spacer and size-designs of the patterned hole area. With the structural-tuning strategies, adequate control of the site-specific sensitivity in the range of 47~83 kPa\u22121 and in the sensing range from 0.1 to 20 kPa was achieved. Moreover, stacked AgNW\/PUA\/AgNW (APA) structural designed pressure sensors with mixed hole sizes of 10\/200 \u00b5m and spacer thickness of 800 \u00b5m exhibited high sensitivity (~171.5 kPa\u22121) in the pressure sensing range of 0~20 kPa, fast response (100~110 ms), and high stretchability (40%). From the results, we envision that the effective structural-tuning strategy capable of controlling the sensing properties of the APA pressure sensor would be employed in a large-area stretchable pressure sensor system, which needs site-specific sensing properties, providing monolithic implementation by simply arranging appropriate micro-patterned hole architectures.<\/jats:p>","DOI":"10.3390\/s20226588","type":"journal-article","created":{"date-parts":[[2020,11,18]],"date-time":"2020-11-18T07:41:00Z","timestamp":1605685260000},"page":"6588","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Locally Controlled Sensing Properties of Stretchable Pressure Sensors Enabled by Micro-Patterned Piezoresistive Device Architecture"],"prefix":"10.3390","volume":"20","author":[{"given":"Jun Ho","family":"Lee","sequence":"first","affiliation":[{"name":"Department of Electrical and Electronics Engineering, Chung-Ang University, Seoul 06974, Korea"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5607-3327","authenticated-orcid":false,"given":"Jae Sang","family":"Heo","sequence":"additional","affiliation":[{"name":"School of Advanced Materials Science and Engineering, Sungkyunkwan University, Suwon 16419, Korea"}]},{"given":"Keon Woo","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Electrical and Electronics Engineering, Chung-Ang University, Seoul 06974, Korea"}]},{"given":"Jae Cheol","family":"Shin","sequence":"additional","affiliation":[{"name":"Department of Electrical and Electronics Engineering, Chung-Ang University, Seoul 06974, Korea"}]},{"given":"Jeong-Wan","family":"Jo","sequence":"additional","affiliation":[{"name":"Electrical Engineering Division, Department of Engineering, University of Cambridge, 9 JJ Thomson Avenue, Cambridge CB3 0FA, UK"}]},{"given":"Yong-Hoon","family":"Kim","sequence":"additional","affiliation":[{"name":"School of Advanced Materials Science and Engineering, Sungkyunkwan University, Suwon 16419, Korea"},{"name":"SKKU Advanced Institute of Nanotechnology (SAINT), Sungkyunkwan University, Suwon 16419, Korea"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9617-2541","authenticated-orcid":false,"given":"Sung Kyu","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Electrical and Electronics Engineering, Chung-Ang University, Seoul 06974, Korea"}]}],"member":"1968","published-online":{"date-parts":[[2020,11,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"795","DOI":"10.1038\/nmat3380","article-title":"A flexible and highly sensitive strain-gauge sensor using reversible interlocking of nanofibres","volume":"11","author":"Pang","year":"2012","journal-title":"Nat.
