This paper presents a review of the characterization and application of EAPap as a flexible mechanical vibration\/strain sensor, bending actuator, and vibration energy harvester. The working mechanism of EAPap is explained along with the various parameters and factors that influence the sensing, actuation, and energy harvesting capabilities of EAPap. Although the piezoelectricity of EAPap is comparable to that of commercially available polyvinylidene fluoride (PVDF), EAPap has the preferable merits in terms of natural abundance and ample capacity of chemical modification. The article would provide guidelines for the characterization and application of EAPap in mechanical sensing, actuation, and vibration energy scavenging, along with the possible limitations and future research prospects.<\/jats:p>","DOI":"10.3390\/s18103474","type":"journal-article","created":{"date-parts":[[2018,10,16]],"date-time":"2018-10-16T02:52:53Z","timestamp":1539658373000},"page":"3474","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":26,"title":["Electro-Active Paper as a Flexible Mechanical Sensor, Actuator and Energy Harvesting Transducer: A Review"],"prefix":"10.3390","volume":"18","author":[{"given":"Asif","family":"Khan","sequence":"first","affiliation":[{"name":"Department of Mechanical, Robotics and Energy Engineering, Dongguk University-Seoul, 30 Pil-dong 1 Gil, Jung-gu, Seoul 04620, Korea"}]},{"given":"Faisal Raza","family":"Khan","sequence":"additional","affiliation":[{"name":"Department of Mechanical, Robotics and Energy Engineering, Dongguk University-Seoul, 30 Pil-dong 1 Gil, Jung-gu, Seoul 04620, Korea"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7057-5174","authenticated-orcid":false,"given":"Heung Soo","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Mechanical, Robotics and Energy Engineering, Dongguk University-Seoul, 30 Pil-dong 1 Gil, Jung-gu, Seoul 04620, Korea"}]}],"member":"1968","published-online":{"date-parts":[[2018,10,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"247","DOI":"10.1088\/0964-1726\/5\/3\/002","article-title":"Smart materials and structures: What are they?","volume":"5","author":"Spillman","year":"1996","journal-title":"Smart Mater.
