From lamps to touchscreens of smartphones, these user interfaces can be found in an array of applications. However, traditional touch sensors are bulky, complicated, inflexible, and difficult-to-wear devices made of stiff materials. The touch screen is gaining further importance with the trend of current IoT technology flexibly and comfortably used on the skin or clothing to affect different aspects of human life. This review presents an updated overview of the recent advances in this area. Exciting advances in various aspects of touch sensing are discussed, with particular focus on materials, manufacturing, enhancements, and applications of flexible wearable sensors. This review further elaborates on the theoretical principles of various types of touch sensors, including resistive, piezoelectric, and capacitive sensors. The traditional and novel hybrid materials and manufacturing technologies of flexible sensors are considered. This review highlights the multidisciplinary applications of flexible touch sensors, such as e-textiles, e-skins, e-control, and e-healthcare. Finally, the obstacles and prospects for future research that are critical to the broader development and adoption of the technology are surveyed.<\/jats:p>","DOI":"10.3390\/s22124460","type":"journal-article","created":{"date-parts":[[2022,6,13]],"date-time":"2022-06-13T06:31:59Z","timestamp":1655101919000},"page":"4460","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":93,"title":["Recent Advances in Touch Sensors for Flexible Wearable Devices"],"prefix":"10.3390","volume":"22","author":[{"given":"Abdul Hakeem","family":"Anwer","sequence":"first","affiliation":[{"name":"School of Mechanical Engineering, Yeungnam University, 280 Daehak-Ro, Gyeongsan 38541, Korea"},{"name":"Industrial Chemistry Research Laboratory, Department of Chemistry, Faculty of Sciences, Aligarh Muslim University, Aligarh 202 002, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nishat","family":"Khan","sequence":"additional","affiliation":[{"name":"Industrial Chemistry Research Laboratory, Department of Chemistry, Faculty of Sciences, Aligarh Muslim University, Aligarh 202 002, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3028-4505","authenticated-orcid":false,"given":"Mohd Zahid","family":"Ansari","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Yeungnam University, 280 Daehak-Ro, Gyeongsan 38541, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sang-Soo","family":"Baek","sequence":"additional","affiliation":[{"name":"Department of Environmental Engineering, Yeungnam University, Gyeongsan 38541, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hoon","family":"Yi","sequence":"additional","affiliation":[{"name":"Mechanical Technology Group, Global Manufacturing Center, Samsung Electro-Mechanics Co., 150 Maeyeong-ro, Yeongtong-gu, Suwon 16674, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Soeun","family":"Kim","sequence":"additional","affiliation":[{"name":"Research Center for Green Fine Chemicals, Korea Research Institute of Chemical Technology, Ulsan 44412, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seung Man","family":"Noh","sequence":"additional","affiliation":[{"name":"Research Center for Green Fine Chemicals, Korea Research Institute of Chemical Technology, Ulsan 44412, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5768-3784","authenticated-orcid":false,"given":"Changyoon","family":"Jeong","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, Yeungnam University, 280 Daehak-Ro, Gyeongsan 38541, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,6,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"26","DOI":"10.1080\/14686996.2020.1862629","article-title":"Flexible wearable sensors\u2014An update in view of touch-sensing","volume":"22","author":"Vu","year":"2021","journal-title":"Sci.
