Neuromorphic Near‐Sensor and In‐Sensor Computing Enabled by Next‐Generation Material‐Based Sensors

Advanced Science, EarlyView.
This Review presents a structural framework that classifies neuromorphic sensing into near‐sensor and in‐sensor architectures, clarifying physical coupling between sensing and computation. The framework connects neural and synaptic device functions with recent advances in optical, mechanical, and chemical sensing, compares energy consumption and ...

Analysis of Electric Field Distribution and Dielectric Breakdown in Transformer Oil under High Voltage Stress [PDF]

Journal of Electrical and Electronics Engineering
In this study we are delving into the behavior of oil under high voltage stress. We tested the oil using an OTS60SX voltage breakdown tester and used three standards: D1816, IEC 60156 and D877.

Effect of partial discharges on thermal breakdown of oil impregnated paper

, 2014
In this paper the effect of partial discharges on the thermal breakdown voltage of oil-impregnated paper is investigated. A disc shaped cavity in a stack of paper sheets formed a PD source. The paper sample was exposed to partial discharges for 18 hours.

Concentration‐Driven Li+ Solvation Engineering with TDMAP‐Based Porphyrin Additives for Dendrite‐Free Li Metal Batteries

Advanced Science, EarlyView.
The electrolyte engineering of introducing tetrakis(4‐N, N‐dimethylaminophenyl)porphyrin (TDMAP) is designed to modulate Li+ solvation structure and solid electrolyte interphase, where the interaction with PF₆− anions is altered (Li+–NMe2–PF₆−). Consequently, the cells with optimal additive concentration achieve high Coulombic efficiency (∼99%), and ...
