Floating Platform Geometry as a Frequency‐Selective Mechanism for Triboelectric Wave Energy Harvesting

SmartSys, Volume 2, Issue 3, September 2026.
ABSTRACT Ocean wave energy has enormous potential for sustainable power generation but conventional technologies often face challenges in efficiency, durability, and adaptability to specific sites. Triboelectric nanogenerators (TENGs) are able to convert irregular and low frequency water motion into electrical energy, but their performance depends on ...

Antistatic High‐Density Polyethylene (HDPE)/Conductive Carbon Black (CCB) Composites for Automotive Parts: Influence of CCB Structure and Molding Technique

Journal of Applied Polymer Science, Volume 143, Issue 29, August 5, 2026.
Antistatic performance in HDPE/conductive carbon black composites is governed not only by filler structure but also by processing. Injection molding induces surface resistivity through skin–core effects, whereas compression molding favors conductive networks.

Self‐Powered Flexible Triboelectric‐Gated Ion‐Gel Transistor for Neuromorphic Tactile Sensing and Human Activity Recognition

Advanced Materials, Volume 38, Issue 37, 2 July 2026.
A fully flexible ion‐gel‐gated graphene‐channel transistor driven by a triboelectric nanogenerator enables self‐powered tactile sensing and synaptic learning. Mimicking spike‐rate‐dependent plasticity, the device exhibits frequency‐selective potentiation and depression, supporting rate‐coded neuromorphic computation even under flex.

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

Advanced Materials Technologies, Volume 11, Issue 13, 8 July 2026.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...
