Aerosol Jet Printed Polymer‐Free High Aspect Ratio Quantum Dot Films for Enhanced Color Conversion
Advanced Optical Materials, EarlyView.Polymer‐free quantum dot color conversion layers are aerosol jet printed at high aspect ratio by tuning the aerosol focus ratio to induce in‐flight droplet drying. Contact‐line pinning suppresses lateral spreading, enabling ∼10 µm‐thick films at ∼50 µm widths with blue light leakage below 0.25% and conversion efficiency approaching 18%, demonstrated ...

Miniaturized Magnetic Tip Design for Endoluminal Vine Robot Navigation
Advanced Robotics Research, EarlyView.A magnetic tip mount is designed for a miniaturized 7 mm soft‐growing vine robot to enable wireless magnetic steering and onboard imaging, while preserving a 3 mm working channel. The internal–external ring magnets design balances magnetic attachment with low eversion pressure. Experiments demonstrate ±90° steering, 34 mm bending radius, and successful

SAW Device Reader Platform using FPGA
, 2010 학위논문(석사)--아주대학교 일반대학원 :전자공학과,2010. 8SAW Device는 ID정보, 온도나 압력 같은 센서정보를 포함할 수 있어 각종 물리센서나 화학 센서 혹은 ID Tag로 다양한 분야로 활용범위가 확대되고 있다. 또한 좁은 대역폭으로 원하는 주파수만을 통과시키는 특성을 갖고 있어 주파수 필터로도 활용되고 있다. 이렇듯 현재 SAW Sensor는 많은 발전을 해왔지만 SAW Sensor를 활용 할 수 있는 플랫폼의 발전은 미흡하기 때문에

Friend, Not Foe: Lowered Tissue Reactivity to Long‐Term Polyimide Implants
Advanced Science, EarlyView.The choice of optimal neural probe designs remains a major challenge in the field of neurotechnology. This study investigated the biocompatibility of several probe variations, including material, thickness, width, and implantation strategy. It highlights the clear advantage of soft polyimide probes over stiff silicon probes for better device ...
