Martin Kaltenbrunner,Tsuyoshi Sekitani,Tsuyoshi Sekitani,Jonathan T. Reeder,Jonathan T. Reeder,Tomoyuki Yokota,Kazunori Kuribara,Takeyoshi Tokuhara,Michael Drack,Reinhard Schwödiauer,Ingrid Graz,Simona Bauer-Gogonea,Siegfried Bauer,Takao Someya,Takao Someya +14 more
TL;DR: In this paper, the authors present a platform that makes electronics both virtually unbreakable and imperceptible on polyimide polysilicon elastomers, which can be operated at high temperatures and in aqueous environments.
Journal ArticleDOI
Organic Nonvolatile Memory Transistors for Flexible Sensor Arrays
Tsuyoshi Sekitani,Tomoyuki Yokota,Ute Zschieschang,Hagen Klauk,Siegfried Bauer,Ken Takeuchi,Makoto Takamiya,Takayasu Sakurai,Takao Someya +8 more
TL;DR: A sensor matrix is realized that detects the spatial distribution of applied mechanical pressure and stores the analog sensor input as a two-dimensional image over long periods of time by integrating a flexible array of organic floating-gate transistors with a pressure-sensitive rubber sheet.
Journal ArticleDOI
Ultraflexible organic photonic skin
Tomoyuki Yokota,Peter Zalar,Martin Kaltenbrunner,Hiroaki Jinno,Naoji Matsuhisa,Hiroki Kitanosako,Yutaro Tachibana,Wakako Yukita,Mari Koizumi,Takao Someya +9 more
TL;DR: This work demonstrates ultraflexible and conformable three-color, highly efficient polymer light-emitting diodes (PLEDs) and organic photodetectors (OPDs) to realize optoelectronic skins (oe-skins) that introduce multiple electronic functionalities such as sensing and displays on the surface of human skin.
Journal ArticleDOI
Inflammation-free, gas-permeable, lightweight, stretchable on-skin electronics with nanomeshes
Akihito Miyamoto,Sungwon Lee,Sungwon Lee,Nawalage Florence Cooray,Sunghoon Lee,Mami Mori,Naoji Matsuhisa,Hanbit Jin,Leona Yoda,Tomoyuki Yokota,Akira Itoh,Masaki Sekino,Hiroshi Kawasaki,Tamotsu Ebihara,Masayuki Amagai,Takao Someya,Takao Someya +16 more
TL;DR: This work shows the successful fabrication of inflammation-free, highly gas-permeable, ultrathin, lightweight and stretchable sensors that can be directly laminated onto human skin for long periods of time, realized with a conductive nanomesh structure.
Journal ArticleDOI
A transparent bending-insensitive pressure sensor
Sungwon Lee,Sungwon Lee,Amir Reuveny,Amir Reuveny,Jonathan T. Reeder,Sunghoon Lee,Sunghoon Lee,Hanbit Jin,Hanbit Jin,Qihan Liu,Tomoyuki Yokota,Tomoyuki Yokota,Tsuyoshi Sekitani,Tsuyoshi Sekitani,Takashi Isoyama,Yusuke Abe,Zhigang Suo,Takao Someya,Takao Someya +18 more
TL;DR: This work shows real-time (response time of ∼20 ms), large-area, normal pressure monitoring under different, complex bending conditions, and test the suitability of the sensor for soft robotics and medical applications.
