Inductance and Electrical Properties of Wireless Power Transmission Coil

Asia-pacific Journal of Multimedia Services Convergent with Art, Humanities, and Sociology, 2016
무선 전력 송수신 기술은 휴대폰이나 전동칫솔 등에 널리 사용되고 있으며, 유연한 충전환경을 제 공하며 전자기기의 크기나 형상 설계에서 좀 더 폭 넓은 자유도를 확보하게 해 준다. 본 연구에서는 ANSYS HFSS 및 Q3D 시뮬레이터를 활용하여, 무선 전력 송수신 코일의 구조 변화에 따라 인덕턴스 및 전기적 특성이 어떻게 변화하는지 조사하였다. Q3D extractor 시뮬레이터에 의해 권선구조 변화에 따른 무선충전 코일의 L 값 변화를 시뮬레이션 하였다. 10턴 2층 구조의 코일의 인덕턴스는 16.4uH 로 계산되었다. 자성재료인 페라이트 소재를 기판으로 사용할 경우 코일의 인덕턴스는 28.0uH로 크게 증가하였다.

Additive‐Manufactured, Multifunctional Bioreactor Technology for Dynamic Culture of 3D Bioprinted Tissue Models

Advanced Materials Technologies, EarlyView.
We introduce an additively manufactured bioreactor with a perfusion flow system and integrated temperature and pH sensors for skeletal muscle tissue biofabrication. The bioreactor's performance was evaluated by assessing the viability, spreading of the myoblast cells in a printed scaffold, and contraction of the isolated murine musculi interossei ...

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering

Advanced Photonics Research, Volume 6, Issue 5, May 2025.
Herein, a mechanically tunable double‐layer plasmonic metamaterial leveraging the extraordinary optical transmission effect observed in subwavelength arrays of openings within thin metal layers is presented. The concept is experimentally validated by integrating the proposed metamaterial structure into an electrostatic parallel‐plate actuator to create

Design and analysis of a decoupled three‐phase coil array for inductive power transfer systems

IET Power Electronics
This article details the design process for a new three‐phase coil array. All of the coils are made to be mutually decoupled from one another which is achieved by introducing a high reluctance path in the ferrite structure for mutual flux using an airgap
