Femtosecond Laser-Induced Co3O4 Periodic Surface Structures of Active Facets for Gas Sensing

Abstract Achieving precise facet control in metal oxides is a critical challenge for advancing gas sensor performance, as high-energy crystal planes offer superior surface reactivity but are difficult to expose in a controlled manner on functional thin films. This work demonstrat...

A Flexible Bimodal Sensor With Single Configuration Enabling Strain and Touchless Sensing

ABSTRACT Human–machine interfaces increasingly require sensors capable of perceiving both direct physical interactions and remote environmental cues. However, existing multimodal flexible sensors typically rely on physically separated sensing units and complex signal integration,...
