TL;DR: In this paper, a new inductive power transfer system with a narrow rail width, a small pickup size, and a large air gap for online electric vehicles is proposed, allowing them to drive freely on specially implemented roads by obtaining power from the buried power supply rail.

TL;DR: In this paper, a cross-segmented power supply rail for roadway-powered electric vehicles is proposed for reducing construction cost and EMF, which consists of two pairs of power cables, core, bidirectional power switches, a transformer, capacitors and harness.

TL;DR: In this article, a novel hydrogen sensor that utilizes the electrical resistance changes in the palladium thin films with nanometer thicknesses is presented, where the sensing mechanism is based on transitory absorption of hydrogen atoms into the Pd layer, which leads to reversible alteration of the electrical resistances.

TL;DR: This work presents a method for exciting surface plasmon polaritons (SPPs) caused by a magnetic field component perpendicular to the direction of slit based on the spatially oscillating induced current along the edges of the slit under obliquely incident electromagnetic waves.

TL;DR: A novel stress-induced method to grow semimetallic Bi nanowires along with an analysis of their transport properties is presented, and four-terminal devices based on individual Bi nanwires were found to exhibit very large transverse and longitudinal ordinary magnetoresistance, indicating high-quality, single crystalline Bi Nanowires.
