Governing Thermal Transport in Three-Dimensional Electronics

Kyubeen Kim, Minho Jin, Sanggeun Bae, Sejin Lee et autres

Thermal management has emerged as a materials bottleneck for three-dimensional integrated circuits, which are being actively explored to enable dense vertical connectivity and mitigate interconnect delay and energy consumption. Unlike 2D-structure chips, stacked tiers confine dissipation within a boundary-rich back-end-of-line (BEOL) heterostructure. …

An AI-driven, wearable, conformal ring system for real-time and user-independent sign language interpretation

Jaejin Park, Yejee Shin, In Sik Min, Yeeun Lee et autres

Sign language translation systems have long aimed to bridge the communication between signers and nonsigners. However, preliminary systems rely on glove-type wearables or wired sensor arrays, which constrain hand movement, reduce comfort, and require nonpersonalized sensor positions that limit adaptability across users. …

Gate dielectric stack design for 2D materials-based electronics

Minho Jin, Hojun Kim, Sejin Lee, Sangmoon Han et autres

Two-dimensional (2D) semiconductors enable atomically thin channels and attractive electrostatics, but practical scaling increasingly hinges on gate-dielectric integration rather than channel performance. A key challenge is forming high-quality dielectrics on chemically inert, dangling-bond-free 2D surfaces while pushing equivalent oxide thickness to the …

2D Silver Nanosheet Assembly for an Isotropic, Stretchable, and Highly Conductive Nanomembrane

Minjeong Kim, Sonwoo Jung, S.S. Kim, Moon‐ki Choi et autres

Abstract Achieving isotropic electrical and mechanical properties is essential for skin‐integrated electronics to operate reliably under complex, multidirectional skin deformations. However, nanomaterial‐based composites in skin electronics often rely on anisotropic filler configurations to meet demanding requirements for high‐quality bio‐interfacing materials, such as …

Transparent, metal-free PEDOT:PSS neural interfaces for simultaneous recording of low-noise electrophysiology and artifact-free two-photon imaging

Hyun Woo Kim, Jiwon Kim, Jong Youl Kim, Kyubeen Kim et autres

Simultaneous two-photon imaging and electrophysiological recordings offer considerable potential for advancing neurological research and therapies. However, traditional metal-based neural interfaces suffer from photoelectric artifacts, while existing transparent implants rely on opaque interconnect lines to address conductivity limitations. Herein, we developed an optically …

Extremely durable electrical impedance tomography–based soft and ultrathin wearable e-skin for three-dimensional tactile interfaces

Kyubeen Kim, Jung-Hoon Hong, Kyubin Bae, Kyounghun Lee et autres

In the rapidly evolving field of human-machine interfaces (HMIs), high-resolution wearable electronic skin (e-skin) is essential for user interaction. However, traditional array-structured tactile interfaces require increased number of interconnects, while soft material-based computational methods have limited functionalities. Here, we introduce a thin …
