Filtering capacitors with wide operating voltage range are essential for smoothing ripples in line-powered system, which still unsatisfactory due to low energy density and limited working scopes. Herein, we report an aqueous hybrid electrochemical capacitor areal specific of 1.29 mF V2 cm-2 at 120 Hz, greater than common ones. Interestingly, it can be easily integrated scale show excellent flexibility, controllable stable filtering performance, device (e.g., seven units series) exhibits...
Abstract Reclaiming kinetic energy from vibrating machines holds great promise for sustainable harvesting technologies. Nevertheless, the impulsive current induced by vibrations is incompatible with conventional storage devices. The energy‐management system necessitates novel designs of soft materials lightweight, miniaturized, and integrated high‐frequency electrochemical Here, this work develops a conductive hydrogel an electro‐responsive polymeric network. breathing transition...
