Journal ArticleDOI
High-performance green flexible electronics based on biodegradable cellulose nanofibril paper
Yei Hwan Jung,Tzu-Hsuan Chang,Huilong Zhang,Chunhua Yao,Qifeng Zheng,Vina W. Yang,Hongyi Mi,Munho Kim,Sang June Cho,Dong-Wook Park,Hao Jiang,Juhwan Lee,Yijie Qiu,Weidong Zhou,Zhiyong Cai,Shaoqin Gong,Zhenqiang Ma +16 more
TL;DR: Successful fabrication of key electrical components on the flexible cellulose nanofibril paper with comparable performance to their rigid counterparts and clear demonstration of fungal biodegradation of the cellulose-nan ofibril-based electronics suggest that it is feasible to fabricate high-performance flexible electronics using ecofriendly materials.
Journal ArticleDOI
Graphene-based carbon-layered electrode array technology for neural imaging and optogenetic applications
Dong-Wook Park,Amelia A. Schendel,Solomon Mikael,Sarah K. Brodnick,Thomas J. Richner,Jared P. Ness,Mohammed R. Hayat,Farid Atry,Seth Frye,Ramin Pashaie,Sanitta Thongpang,Zhenqiang Ma,Justin C. Williams +12 more
TL;DR: An array of interfacing abilities of the CLEAR device are demonstrated and its utility for neural applications, including optogenetic activation of focal cortical areas directly beneath electrodes, in vivo imaging of the cortical vasculature via fluorescence microscopy and 3D optical coherence tomography.
Journal ArticleDOI

TL;DR: The transparent ability of graphene neural electrodes is demonstrated and provides a method to further increase understanding and potentially improve therapeutic electrical stimulation in the central and peripheral nervous systems.
Journal ArticleDOI
Fabrication and utility of a transparent graphene neural electrode array for electrophysiology, in vivo imaging, and optogenetics
Dong-Wook Park,Sarah K. Brodnick,Jared P. Ness,Farid Atry,Lisa Krugner-Higby,Amelia A Sandberg,Solomon Mikael,Thomas J. Richner,Joseph Novello,Hyungsoo Kim,Dong Hyun Baek,Jihye Bong,Seth Frye,Sanitta Thongpang,Kyle I. Swanson,Wendell Lake,Ramin Pashaie,Justin C. Williams,Zhenqiang Ma +18 more
TL;DR: This protocol describes how to fabricate and implant a graphene-based microelectrocorticography (μECoG) electrode array and subsequently use this alongside electrophysiology, fluorescence microscopy, optical coherence tomography (OCT), and optogenetics to help to expand the boundaries of neurophysiological experimentation.
Journal ArticleDOI
Hysteresis mechanism and reduction method in the bottom-contact pentacene thin-film transistors with cross-linked poly(vinyl alcohol) gate insulator
TL;DR: In this article, the origin of the hysteresis phenomenon in bottom-contact pentacene organic thin-film transistors with cross-linked polyvinyl alcohol (PVA) insulator is studied.
