Intelligent Acousto‐Electrical Metamaterials (IAM) for Sound Source Detection

Advanced Materials, Volume 38, Issue 36, 26 June 2026.
Our proposed metamaterial concept enables sound source detection using a single material, in contrast to conventional arrays that require dozens or even hundreds of transducers. We show that the coupled acoustic–vibrational–electrical responses in piezoelectric metamaterials give rise to topology‐governed charge transport, producing distinct voltage ...

Stress‐Normalized Sensitivity as a Comparative Benchmark for Intrinsically Piezoresistive Nanocomposite Materials in Wearable Electronics

Advanced Materials Technologies, Volume 11, Issue 12, 18 June 2026.
A stress‐normalised sensitivity metric (S = G/Y) is introduced as a materials‐level benchmark for intrinsically piezoresistive nanocomposites. By decoupling electromechanical response (G) from stiffness (Y), the framework enables direct comparison across diverse systems and clarifies design trade‐offs for wearable sensors.

Microstructured Electrode‐Piezopolymer Interface for Ultrasound Transducers With Enhanced Flexibility and Acoustic Performance

Advanced Materials Technologies, Volume 11, Issue 12, 18 June 2026.
Flexible piezopolymer ultrasound transducers are engineered by tailoring the electrode–piezopolymer interface using metallic, flake‐based, and porous graphene electrodes. Laser‐induced graphene's porous structure enables polymer infiltration, strengthening interfacial coupling and enhancing piezoelectric response and acoustic output.

A Study on Enhancing Stability and Conductivity of ZnO Through Controlled Doping

Advanced Theory and Simulations, Volume 9, Issue 6, June 2026.
First principles modelling reveals vanadium and indium as complementary tuning knobs in cubic ZnO, enabling controlled changes in optical absorption, dielectric screening, and frequency‐dependent conductivity. Moderate doping maximizes optoelectronic gain, while higher loading can trigger mechanical softening.

Improving the efficiency of a hollow ultrasonic motor by optimizing the stator’s effective electromechanical coupling coefficient

Review of Scientific Instruments, 2020
For application in control moment gyros, we considered a hollow traveling wave ultrasonic motor with a diameter of 70 mm. The effective electromechanical coupling coefficient (EMCC) of the stator was determined. The influence of the vibration mode of the stator and the structural dimensions of the metal elastomer and piezoelectric ceramic ring on the ...
