Self‐Folded Corrugated Origami Sensor Based on Triboelectric Nanogenerator for a Smart Cushioning Device

Advanced Materials Technologies, EarlyView.
A corrugated origami TENG (CO‐TENG) soft sensor utilizes paper self‐folding technology to create battery‐free devices by laminating and folding sheet materials. In the object drop test, the voltage generated by CO‐TENG is classified with machine learning to achieve an accuracy of 98.9%, which shows its potential for smart cushioning devices.

Interplay Between Acoustical and Mechanical Properties in Lattice Structures: A Geometrical Perspective

Advanced Materials Technologies, EarlyView.
This perspective presents an in‐depth analysis of the structural‐property relationships between acoustic and mechanical properties in lattice structures. It introduces the concept of “acoustical geometry” and identifies the limitations of traditional lattice designs in simultaneously optimizing sound absorption and mechanical performance.

Piezoelectric Polyurethane/Barium Titanate Composites with High Stretchability and Voltage Output for Energy Harvesting in Soft Wearable Electronics

Advanced Materials Technologies, EarlyView.
Piezoelectric additives are combined with an elastomer host, creating a material with properties of both parent materials: high voltage output and exceptional stretchability. These stretchable piezoelectric materials have the robustness for integration into soft wearable electronics, functioning as renewable energy harvesters to charge capacitors.

The Influence of the Supporting Substrate on Single‐Particle Circular Differential Scattering of DNA Assembled Nanorod Dimers

Advanced Optical Materials, EarlyView.
For most microscopy measurements the sample is placed on a substrate, which causes symmetry breaking, especially relevant for chiral plasmonic nanostructures. DNA origami mediated X‐shaped AuNR dimers showing high structural purity in solution, exhibit significant diversity in lineshapes and signal intensities for their circular differential scattering

Origin of the Laser‐Induced Picosecond Spin Current Across Magnetization Compensation in Ferrimagnetic GdCo

Advanced Optical Materials, EarlyView.
Picosecond spin current pulses generated by ferrimagnetic GdCo are studied via THz emission spectroscopy. Due to the GdCo micromagnetic structure, the spin current vanishes at compensation when a magnetic field is applied but persists for zero field. At room temperature, the THz spin current is dominated by Co. At low temperatures, Gd can significantly
