Stretchable patterned graphene gas sensor driven by integrated micro-supercapacitor array
Junyeong Yun,Yein Lim,Gwon Neung Jang,Daeil Kim,Seung Jung Lee,Heun Park,Soo Yeong Hong,Geumbee Lee,Goangseup Zi,Jeong Sook Ha,Jeong Sook Ha +10 more
TL;DR: A stretchable patterned graphene gas sensor driven by integrated micro-supercapacitor (MSC) array on the same deformable substrate was designed to suppress the applied strain on the gas sensor and MSCs via insertion of stiff platforms of SU-8 underneath and serpentine electrical interconnections of polymer-encapsulated long and narrow Au thin film as discussed by the authors.
