Microwall‐Integrated Terahertz Metasurfaces for Spatially Guided Label‐Free Sensing of Micrometer‐Scale Plastic Particles

Advanced Materials Technologies, EarlyView.
A THz metasurface device integrating a metal–dielectric–metal resonator with microwall‐defined recessed regions enables spatially guided, label‐free sensing of micrometer‐scale plastic particles. The as‐fabricated devices exhibit distinct THz reflection resonances for 3.1‐µm polystyrene particles and a concentration‐dependent resonance‐frequency‐shift ...

Thermoresponsive Self‐Healing Carbon Nanotube‐Reinforced Dual‐Network Hydrogels for Wearable Sensors and Information Concealment

Advanced Materials Technologies, EarlyView.
A CNT‐reinforced dual‐network hydrogel combines ionic liquid‐mediated thermoresponsiveness, dynamic covalent crosslinking, and conductive nanostructures within a single adaptive material. The hydrogel exhibits ultrafast gelation, autonomous self‐healing, >1000% stretchability, reversible optical switching, and stable electromechanical sensing, enabling

Class E2 resonant DC/DC power convertor

IEE Proceedings G Circuits, Devices and Systems, 1990
A new high-frequency high-efficiency resonant DC/DC convertor is introduced. It is composed of a Class E inverter and a Class E rectifier. The convertor operates with load resistances ranging from a full load to infinity. It can regulate the output voltage by varying the switching frequency over a narrow range, owing to a high value of the loaded ...

Design and analysis of the LCL resonant convertor in inductive Power Transfer system

2014 International Power Electronics and Application Conference and Exposition, 2014
In inductive Power Transfer (IPT) application, minimum supply VA rating and convertor conduction loss are two important design purposes. The LCL resonant convertor can achieve both of these objects when designed appropriately. In this paper, the LCL resonant tank is changed into two LC resonant networks, then the unity power factor compensation ...

Study of a modified parallel resonance AC-DC convertor with unity power factor and high efficiency

Proceedings 1995 Canadian Conference on Electrical and Computer Engineering, 2002
This article proposes a new topology and control strategy to optimise the power factor of a parallel resonance AC/DC convertor of high power while retaining high efficiency. The static and dynamic characteristics determined by the phase-plane method and the results obtained from simulation with Matlab software are detailed and analysed with an example ...
