Journal ArticleDOI
Hybrid graphene electrode for the diagnosis and treatment of epilepsy in free-moving animal models
Jeongsik Lim,Sangwon Lee,Jejung Kim,Jeonghoon Hong,Sooho Lim,Kyungtae Kim,Jeongwoo Kim,Sungchil Yang,Sung Chil Yang,Jong Hyun Ahn +9 more
TL;DR: In this paper , a high-density, flexible electrode array comprising graphene/Au/graphene that stably wraps onto the cortex surface of a living rat brain, exhibiting a superior signal-to-noise ratio.
Proceedings ArticleDOI
Ultrafast terahertz spectroscopy of the inverse giant piezoresistance effect in silicon nanomembranes
TL;DR: In this article, the inverse piezoresistance effect in silicon nanomembranes was observed and it was shown that the effect originates from the carrier-concentration changes via charge carrier trapping into strain-induced defect states.
Journal ArticleDOI
Thermal Investigations of Hemispherical Shell Vapor Chamber Heat Sink
TL;DR: In this article , a hemispherical shell vapor chamber (HSVC) was proposed and manufactured, which consists of a very short evaporator space and a large condenser area with an inner and outer surface.
Patent
Transient sensor based on molybdenum disulfide and manufacturing method thereof
TL;DR: In this paper, a transient sensor using molybdenum disulfide and a manufacturing method for its use in a living subject was described. But the method was not described.
Proceedings ArticleDOI
