Electrical and electronic engineering is the branch of engineering that makes use of electricity. Electrical engineering concentrates on systems for generating and transmitting large electrical currents and converting them into other forms of energy, such as mechanical motion. Electronic engineering focusses on lower energy currents for processing and communicating information.
Future bioinspired locomotion systems need design’s agility and adaptiveness. Here, the authors report a musculoskeletal leg design which leverages multi-layered electrohydraulic actuators to achieve highly energy-efficient and versatile motion.
Humayun Zubair Khan and colleagues design a thin and efficient metasurface for polarisation conversion. Their solution can operate to up to 45-degree incidence angles and is suitable for satellite communications which use separated frequency bands with orthogonal circularly polarised waves.
Modern communication applications may demand devices with tunable performances and simple fabrications. Here, we show strain dependent, adjustable RF/microwave performance by applying patterns of conductive Ti3C2Tx MXene coatings on low-cost acetate substrates in a straightforward coating process.
An article in IEEE Journal on Selected Areas in Communications presents a cooperative framework that integrates satellite routing and frequency assignment to avoid self-interference in large satellite constellations.
The further development of transistors based on two-dimensional transition metal dichalcogenides faces various issues, starting with the high density of defects typically found in the materials.
