Textile‐Based Capacitive Pressure Sensors Enabled by Ultrasonic Spray‐Coated Carbon Black Electrodes and Electrostatic Flocking

Advanced Materials Interfaces, EarlyView.
A 4‐layer Kevlar‐based composite is fabricated by combining ultrasonic spraying and electrostatic flocking. Carbon black dispersion is first deposited onto Kevlar fabric to create a conductive electrode. Nylon fibers are then electrostatically flocked onto the coated fabric, forming a dielectric layer.

Spike‐Type Band Alignment via in2Se3/CuI Charge‐Transport Engineering Enables 26% Efficient Lead‐Free RbSn0.5Ge0.5I3 Perovskite Solar Cells

Advanced Materials Interfaces, EarlyView.
A lead‐free and Cd‐free RbSn₀.5Ge₀.5I3 perovskite solar cell is optimized through In2Se3/CuI charge‐transport engineering using SCAPS‐1D. Spike‐type band alignment suppresses interfacial recombination, enhances charge extraction, and achieves a power conversion efficiency of 26.01%, providing an effective strategy for high‐performance and ...

Additively Manufactured Porous Ceramics as Tunable Dielectrics for Passive Temperature Sensing

Advanced Materials Technologies, EarlyView.
Porous ceramic lattices, 3D‐printed from a multicomponent oxide ink, are integrated with LC resonators for passive wireless temperature sensing. By tuning porosity, the dielectric properties and RF response are engineered to produce distinct resonant frequency shifts with temperature. The results establish a structure‐driven approach to customizing the

Skin‐Like Tri‐Modal Sensors Based on Soft Piezoelectric and Ionic Composites

Advanced Materials Technologies, EarlyView.
Inspired by the multimodal perception of human skin, a soft, skin‐like tri‐modal sensor is presented. The device incorporates an ionically conductive, piezoelectric, elastic composite as its active layer, enabling independent detection of temperature, static strain, and dynamic strain within a single two‐terminal architecture.
