Pressure is one of the key stimuli in e\u2010skin technology, frequently detected using piezoresistive sensors, which consist of film layers commonly micro\u2010structured to improve their performance, either through expensive photolithography techniques or other poorly customizable approaches. The authors\u2019 group recently introduced laser engraving as a low\u2010cost yet highly customizable micro\u2010structuring technique to produce molds, despite the limited resolution. Combining laser engraving with shrinking polymeric films (SPFs) to fabricate molds is an innovative strategy to greatly improve the performance of the sensors, allowing for thinner and highly conformal sensor layers while minimizing costs. Shrinking these SPFs after their engraving yields smaller yet high aspect ratio cavities. Herein, all the laser engraving parameters are thoroughly investigated to optimize SPF molds (arrays of 10\u00a0\u00b5m vertical lines spaced by 200\u00a0\u00b5m, engraved with 3% laser power, 25% speed, and 0.04'\u2019 between laser and substrate) to produce e\u2010skin piezoresistive sensors with a sensitivity of \u22121.4\u00a0kPa<jats:sup>\u22121<\/jats:sup> below 10\u00a0kPa, a 1.4\u00a0ms recovery time, and a capability to detect distinct body movements, illustrating the great potential for health monitoring applications.<\/jats:p>","DOI":"10.1002\/admi.202100877","type":"journal-article","created":{"date-parts":[[2021,10,15]],"date-time":"2021-10-15T10:25:02Z","timestamp":1634293502000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["E\u2010Skin Piezoresistive Pressure Sensor Combining Laser Engraving and Shrinking Polymeric Films for Health Monitoring Applications"],"prefix":"10.1002","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2820-2125","authenticated-orcid":false,"given":"Andreia","family":"dos Santos","sequence":"first","affiliation":[{"name":"ALMASCIENCE \u2013 Investiga\u00e7\u00e3o e Desenvolvimento em Celulose para Aplica\u00e7\u00f5es Inteligentes e Sustent\u00e1veis  Campus da Caparica Caparica 2829\u2010516 Portugal"},{"name":"i3N\/CENIMAT Department of Materials Science Faculty of Science and Technology Universidade NOVA de Lisboa and CEMOP\/UNINOVA  Campus de Caparica Caparica 2829\u2010516 Portugal"}]},{"given":"Elvira","family":"Fortunato","sequence":"additional","affiliation":[{"name":"i3N\/CENIMAT Department of Materials Science Faculty of Science and Technology Universidade NOVA de Lisboa and CEMOP\/UNINOVA  Campus de Caparica Caparica 2829\u2010516 Portugal"}]},{"given":"Rodrigo","family":"Martins","sequence":"additional","affiliation":[{"name":"i3N\/CENIMAT Department of Materials Science Faculty of Science and Technology Universidade NOVA de Lisboa and CEMOP\/UNINOVA  Campus de Caparica Caparica 2829\u2010516 Portugal"}]},{"given":"Hugo","family":"\u00c1guas","sequence":"additional","affiliation":[{"name":"i3N\/CENIMAT Department of Materials Science Faculty of Science and Technology Universidade NOVA de Lisboa and CEMOP\/UNINOVA  Campus de Caparica Caparica 2829\u2010516 Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6608-3422","authenticated-orcid":false,"given":"Rui","family":"Igreja","sequence":"additional","affiliation":[{"name":"i3N\/CENIMAT Department of Materials Science Faculty of Science and Technology Universidade NOVA de Lisboa and CEMOP\/UNINOVA  Campus de Caparica Caparica 2829\u2010516 Portugal"}]}],"member":"311","published-online":{"date-parts":[[2021,10,11]]},"reference":[{"key":"e_1_2_8_1_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-662-01128-7_10"},{"key":"e_1_2_8_2_1","volume-title":"Textbook of Medical Physiology","author":"Guyton A.
