Engineering Triboelectric Paper for Energy Harvesting and Smart Sensing

Advanced Materials, EarlyView.
Engineering nano‐graphite coated paper (NG@P) is produced to serve as triboelectric layers and electrodes for TENGs. Ultra‐high power density above 14 kW m−2 is achieved due to the electrostatic discharge on the surface. Moreover, smart home sensors are fabricated using the NG@P for motion sensing and sleep monitoring, which could be used for security ...

Green Fabrication of Sulfonium‐Containing Bismuth Materials for High‐Sensitivity X‐Ray Detection

Advanced Materials, EarlyView.
[(CH3CH2)3S]6Bi8I30 and [[(CH3CH2)3S]AgBiI5 are introduced as novel X‐ray detector materials with exceptional sensitivity and low detection limits. Produced via scalable, green synthesis, they remain highly durable after 9 months of storage and continuous X‐ray use, setting a new benchmark for medical imaging and outperforming many existing and ...

Synthetic Active Liquid Crystals Powered by Acoustic Waves

Advanced Materials, EarlyView.
A fully synthetic active liquid crystal, energized by an acoustic field, is presented. This system exhibits active nematic behavior, tunable topological defect dynamics, and persistent hydrodynamic vortices at high activity levels. The material maintains stable properties while enabling precise activity control in a wide range.

A Body Conformal Ultrasound Receiver for Efficient and Stable Wireless Power Transfer in Deep Percutaneous Charging

Advanced Materials, EarlyView.
Implantable devices rely on batteries that demand surgical replacement, posing risks, and financial burdens. Ultrasound energy transfer (US‐ET) offers a revolutionary wireless alternative but struggles with efficiency. The presented dielectric‐ferroelectric‐boosted US‐TENG (US‐TENGDF‐B) is thin, flexible, and biocompatible that provides high‐efficiency
