Pressure-labelled tactile perception in robotics enabled by a skin-inspired dual-mode triboelectric sensor and neural networks

Kequan Xia, Song Yang, Dong Qiang, Oli Prendergast et autres

—Artificial intelligence (AI) enabled biomedical robots rely on tactile perception, but tactile sensing is limited by force induced variability that mixes material signals with contact pressure. Here, we introduce a pressure-labelled tactile intelligence framework built on a bioinspired tactile sensor (BT sensor) …

A Coupled Elastohydrodynamic–Acoustic Framework for High-Resolution Ultrasonic Measurement of Dynamic Film Thickness in Lubricated Contacts

Pan Dou, Yayu Li, Suhaib Ardah, Tonghai Wu et autres

The thickness of the lubricating film plays a vital role in the operational efficiency and reliability of rolling bearings. Ultrasonic reflection techniques offer a promising noninvasive approach for the in situ evaluation of lubricant films. However, accurate identification of the central film …

Multiscale Dynamics of Roughness-Driven Flow in Soft Interfaces

Qian Wang, Suhaib Ardah, Tom Reddyhoff, Daniele Dini

Soft lubricated contacts exhibit complex interfacial behaviours governed by the coupled effects of multiscale surface roughness and non-linear fluid-solid interactions. Accurately capturing this interplay across thin-film flows is challenging due to the strong synergy between contact mechanics and hydrodynamic flow, spanning over …

Taking charge off droplets: Introducing the multi-point electrode TENG

Oli Dylan Prendergast, Giulio Fatti, Andrew S. Holmes, Tom Reddyhoff

Droplet triboelectric nanogenerators (D-TENGs) offer a promising route for ambient energy harvesting, yet their efficiency remains limited by poorly understood and suboptimal charge transfer mechanisms. Here, we introduce a novel point electrode design (P-TENG) that decouples the surface electrode from the dielectric, …
