The Dynamic Energy Band Model of Contact‐Separation and Sliding Mode Triboelectric Charging of Polymers at the Metal‐Polymer Interface

open access: yesAdvanced Science, EarlyView.
Triboelectric charge generation at polymer‐metal interfaces arises from the interplay of intra‐ and inter transformation reactions of mechanochemically generated species, physical properties of polymers, environmental conditions. The direction and the magnitude of electron transfer between metal and polymer are dynamically governed by the relative ...

Deformation Driven Suction Cups: A Mechanics‐Based Approach to Wearable Electronics

open access: yesAdvanced Science, EarlyView.
Deformation‐driven suction cups enable robust, reversible adhesion of wearable electronics to human skin spanning wide mechanical compliance, without adhesives or tight straps. By integrating mechanics modeling, experiments, and contact mechanics theory, this work reveals how cup geometry, substrate compliance, and interfacial adhesion govern suction ...

Ultrastrong TEMPO‐Oxidized Densified Bamboo via Interface Decoupling and Hierarchical Toughening

open access: yesAdvanced Science, EarlyView.
This study develops TEMPO‐oxidized densified bamboo that achieves ultrahigh strength and toughness by decoupling rigid hydrogen bonds into reversible van der Waals interactions. TEMPO oxidation reorganizes the cellulose hydrogen‐bonding network, facilitating energy dissipation via reversible interactions, thereby establishing a general strategy to ...
