High-voltage transmission lines are the main facilities for power transmission, and they mainly composed of aluminum conductor steel-reinforced (ACSR). Over long-term outdoor use, overhead will encounter lightning strikes, chemical pollutant corrosion, deicing, wind vibration, other external forces. This often results in a series potential failures, such as breakage, strands. In order to ensure...

The design of an optical current sensor to be used in a pulsed power generator is presented. The current sensor is based on the polarization rotation by the Faraday effect. GEPOPU is a pulsed power generator, 110 kA, 120 ns double transit time, 1.5 Ω coaxial geometry, and current rise time of 50 ns. Two different optical geometries surrounding the conductor were tried, using Amici roof prism an...

This paper presents a miniaturized Doppler radar that can be used as a motion sensor for low-cost Internet of things (IoT) applications. For the first time, a radar front-end and its antenna are integrated on a multilayer cellulose-based substrate, built-up by alternating paper, glue and metal layers. The circuit exploits a distributed microstrip structure that is realized using a copper adhesi...

In recent years, exhaust sensors have become increasingly attractive for use in energy and environmental technologies. Important issues regarding practical applications of these sensors, especially for soot measurements, include the further development of ion-conductive electrolytes and active electrode catalysts for meeting performance and durability requirements. Herein, we design a proton co...

We have developed a significantly improved chemiresistor for sensing volatile organic compounds that consists of Au-coated Ni particles organized into electrically conducting pathways in a polymer matrix by a magnetic field [1]. This sensor overcomes the problems inherent to conventional carbon-black chemiresistors, while achieving an unprecedented magnitude of response. When exposed to chemica...
