Understanding the Roles of Microstructure and Viscoelasticity of Soft Ionic Elastomer for Super‐Capacitive Pressure Sensors

open access: yesAdvanced Science, EarlyView.
By engineering the PVA/H3PO4 ionic elastomer with optimized viscoelasticity and a height‐graded microstructure, the pressure sensor achieves a broad linear range up to 2000 kPa and a high sensitivity of 2.70 nF/kPa. These advancements underscore its strong potential for wearable electronics, including bio‐signal detection, health monitoring, and ...

Feline‐Inspired Robot Enabled by Combustion‐Driven Actuators for Agile Motion and High‐Payload Obstacle Traversal

open access: yesAdvanced Science, EarlyView.
Inspired by nature's competitive maneuvers, this study introduces a combustion‐driven soft actuator that powers a multi‐modal “Jump‐and‐Fly Catbot” (JFC). With millisecond response, high‐force output (over 70 times its weight) and precise control (error within 5%), the robot can jump, fly, hover, and escape from challenging environments, achieving ...

Co3O4/C‐NFs Induced 3D Electric Field Enhancement for Dual‐Regulation of Polysulfides and Li+ Transport in Lithium–Sulfur Batteries

open access: yesAdvanced Science, EarlyView.
A nano‐framework structured Co3O4/C catalyst with 3D electric field enhancement is designed to facilitate the mass transfer of both Li⁺ and lithium polysulfides (LiPSs) in lithium–sulfur batteries (LSBs). The enhanced electric‐field–driven migration significantly accelerates sulfur reduction reaction (SRR) kinetics while suppressing the shuttle effect ...
