The use of multifunctional sensors is always challenging, especially when their energy requirements are considered. Herein, the heterogeneous integration of custom\u2010made flexible organic photovoltaic (OPV) cells is demonstrated with a large area touch sensor array. The OPV can offer power density of more than 0.32\u2009\u03bcW\u2009cm<jats:sup>\u22122<\/jats:sup> at 1500\u2009lux, which is sufficient to meet the instantaneous demand of the array of touch sensors. In addition to energy harvesting, it is shown that the OPVs can perform shadow sensing for proximity and gesture recognition, which are crucial features needed in the e\u2010Skin, particularly for safe interaction in the industrial domain. Along with pressure sensing (sensitivity of up to 0.26\u2009kPa<jats:sup>\u22121<\/jats:sup> in the range of 1\u201310\u2009kPa) and spatial information, the touch sensors made of indium tin oxide and monolayer graphene have shown &gt;70% transparency, which allow light to pass through them to reach the bottom OPV layer. With better resource management and space utilization, the presented stacked integration of transparent touch\u2010sensing layer and OPVs can evolve into a futuristic energy\u2010autonomous e\u2010Skin that can \u201csee\u201d and \u201cfeel.\u201d<\/jats:p>","DOI":"10.1002\/aisy.202300103","type":"journal-article","created":{"date-parts":[[2023,7,26]],"date-time":"2023-07-26T03:15:56Z","timestamp":1690341356000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":28,"title":["Self\u2010Powered e\u2010Skin Based on Integrated Flexible Organic Photovoltaics and Transparent Touch Sensors"],"prefix":"10.1002","volume":"5","author":[{"given":"Nitheesh M.","family":"Nair","sequence":"first","affiliation":[{"name":"James Watt School of Engineering University of Glasgow  Glasgow G12 8QQ UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dhayalan","family":"Shakthivel","sequence":"additional","affiliation":[{"name":"James Watt School of Engineering University of Glasgow  Glasgow G12 8QQ UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kumar M.","family":"Panidhara","sequence":"additional","affiliation":[{"name":"Materials Engineering Department Indian Institute of Science Bangalore  Bangalore 560012 India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Varun","family":"Adiga","sequence":"additional","affiliation":[{"name":"Interdisciplinary Centre for Energy Research Indian Institute of Science Bangalore  Bangalore 560012 India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Praveen C","family":"Ramamurthy","sequence":"additional","affiliation":[{"name":"Interdisciplinary Centre for Energy Research Indian Institute of Science Bangalore  Bangalore 560012 India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3858-3841","authenticated-orcid":false,"given":"Ravinder","family":"Dahiya","sequence":"additional","affiliation":[{"name":"Bendable Electronics &amp; Sustainable Technologies (BEST) Group Northeastern University  Boston MA 02115 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,7,26]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/aisy.202200183"},{"key":"e_1_2_8_2_2","doi-asserted-by":"publisher","DOI":"10.1002\/advs.202201525"},{"key":"e_1_2_8_2_3","doi-asserted-by":"publisher","DOI":"10.1126\/scirobotics.abl7344"},{"key":"e_1_2_8_2_4","doi-asserted-by":"publisher","DOI":"10.1002\/aelm.202101348"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/aisy.202100036"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1109\/JSSC.2020.3035491"},{"key":"e_1_2_8_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.joule.2021.06.004"},{"key":"e_1_2_8_4_3","doi-asserted-by":"publisher","DOI":"10.1002\/adma.202100899"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/aisy.201900051"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.3390\/s19092170"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/adma.202200724"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.apmt.2018.07.004"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41528-018-0045-x"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1002\/adfm.201606287"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1002\/advs.201802251"},{"key":"e_1_2_8_12_1","unstructured":"A.Varshney A.Soleiman L.Mottola T.Voigt inProc. of the 4th ACM Workshop on Visible Light Communication Systems Association for Computing Machinery Snowbird UT2017."},{"key":"e_1_2_8_13_1","first-page":"1","volume-title":"IEEE Transactions on Mobile Computing","author":"Ma D.","year":"2022"},{"key":"e_1_2_8_14_1","volume-title":"IEEE Int.
