Self‐Assembled Inorganic Nanomembrane Tubes: Rolled‐Up Piezoelectrics for Microacoustic Wave‐Based Actuators and Sensors

Advanced Materials, EarlyView.
This study demonstrates a self‐assembly process to generate free‐standing piezoelectric nanomembranes, forming ultracompact microtubular acoustic wave sensors and actuators. The miniaturized 3D piezoelectric platform reported in this work can be applied in telecommunication, energy harvesting, and acoustofluidics. Moreover, the 3D self‐assembly can add

High‐Sensitivity Terahertz Gas Sensing Enabled by Undercut Metal‐Dielectric‐Metal Metamaterial

Advanced Materials Interfaces, EarlyView.
A terahertz (THz) metamaterial gas sensor is demonstrated using a metal–dielectric–metal (MDM) absorber with an undercut dielectric layer, which enlarges the gas‐replaced volume and strengthens refractive‐index perturbation of the resonant mode. A reflection dip at 0.766 THz is observed, and acetone–nitrogen tests yield concentration‐dependent shifts ...
