===Flexible devices===
[[Flexible electronics]] are [[polymer]]s or other flexible materials (e.g. [[silk]],<ref name="KimSilk">{{cite journal | vauthors = Kim DH, Viventi J, Amsden JJ, Xiao J, Vigeland L, Kim YS, Blanco JA, Panilaitis B, Frechette ES, Contreras D, Kaplan DL, Omenetto FG, Huang Y, Hwang KC, Zakin MR, Litt B, Rogers JA | display-authors = 6 | title = Dissolvable films of silk fibroin for ultrathin conformal bio-integrated electronics | journal = Nature Materials | volume = 9 | issue = 6 | pages = 511–517 | date = June 2010 | pmid = 20400953 | pmc = 3034223 | doi = 10.1038/nmat2745 | bibcode = 2010NatMa...9..511K }}</ref> [[pentacene]], [[polydimethylsiloxane|PDMS]], [[Parylene]], [[polyimide]]<ref name="Boppart">{{cite journal | vauthors = Boppart SA, Wheeler BC, Wallace CS | title = A flexible perforated microelectrode array for extended neural recordings | journal = IEEE Transactions on Bio-Medical Engineering | volume = 39 | issue = 1 | pages = 37–42 | date = January 1992 | pmid = 1572679 | doi = 10.1109/10.108125 | s2cid = 36593459 }}</ref>) printed with [[circuitry]]; the flexibility allows the electronics to bend. The [[semiconductor device fabrication|fabrication techniques]] used to create these devices resembles those used to create [[integrated circuit]]s and [[microelectromechanical systems]] (MEMS).{{Citation needed|date=December 2019|reason=removing citation to predatory publisher content}}
