Advances in Wearable Thermoelectric Devices: Strategies for Enhancing Wearability and Performance

open access: yesSmall Science, Volume 6, Issue 9, September 2026.
This review introduces wearable thermoelectric devices as body‐integrated systems rather than isolated energy devices. It explains how their performance depends not only on thermoelectric materials but also on skin contact, mechanical compliance, electrical interfaces, and heat‐flow design.

Nanoscopic Observation of Structural Changes After First‐Firing Behavior in W/GeTe/W Ovonic Threshold Switches Using AFM Tip–Based Local Biasing

open access: yesSmall Methods, Volume 10, Issue 17, 9 September 2026.
A local‐biasing system using AFM induces site‐specific threshold switching in Ge0.17Te0.83 films, enabling direct observation of crystalline/amorphous interface formation. First‐principles calculations reveal that this structural change induces Te 5p‐dominated mid‐gap states and electric field‐enhanced charge redistribution.

Color‐Pure and Stable Amber Perovskite Quantum Dot Films With Dramatically Enhanced Light Extraction

open access: yesSmall Structures, Volume 7, Issue 9, September 2026.
The amber gap, the low emission efficiency of amber light in white light‐emitting diodes (WLEDs), is addressed here through amber perovskite quantum dots (APQDs) with 84% photoluminescence quantum yield (PLQY). Embedding hexagonal boron nitride (h‐BN) particles within the APQD/polymethyl methacrylate (PMMA) matrix redirects light trapped in waveguide ...
