Assessing the effects of power quality on partial discharge behaviour through machine learning [PDF]
, 2010 Partial discharge (PD) is commonly used as an indicator of insulation health in high voltage equipment, but research has indicated that power quality, particularly harmonics, can strongly influence the discharge behaviour and the corresponding pattern ...

Robust Polymer Hydrogels Improve Electric‐Fish‐Inspired Batteries
Advanced Functional Materials, EarlyView.ABSTRACT Electric‐fish‐inspired hydrogel batteries based on ion‐concentration gradients offer an attractive route to soft power sources; however, the poor mechanical properties of existing hydrogels limit device assembly and performance. Here, we report poly(ethylene glycol) methyl ether acrylate hydrogels that enable ion‐gradient batteries composed of
