Wafer‐Scale Top‐Down Patterning of Metal Halide Perovskites

open access: yesAdvanced Materials Technologies, EarlyView.
Wafer‐scale patterning of metal halide perovskite films is demonstrated on 150 mm substrates using a chemically amplified resist, polymethyl methacrylate (CAR‐PMMA) and a single reactive ion etching step. The streamlined process preserves film luminescence while defining submicrometer features across the full wafer, enabling dense, scalable integration

Microscale 3D‐Printed Digital Strain Switches for Embedded Mechanical Computation

open access: yesAdvanced Materials Technologies, EarlyView.
Microscale 3D‐printed strain switches on flexible films convert deformation into native digital signals at geometry defined thresholds. A closed form model predicts switching from 3000 to 15 000 microstrain and is validated across 110 devices. Reliable ohmic closure and strain activated AND, OR, and XOR logic point toward low‐power mechanical ...

3D‐Printed Actuator Powered by Liquid Crystal Elastomer Muscles at the Water–Air Interface

open access: yesAdvanced Materials Technologies, EarlyView.
Soft robots for unstructured environments require responsive, durable actuators. Liquid crystal elastomers (LCEs) provide large reversible deformations under thermal or optical stimuli. Direct ink writing enables fabrication of LCE actuators integrated with silicone, with mesogen chemistry and oligomers optimized for printable inks.

A Fully Lithography‐Free Fabrication Strategy for Organic Electrochemical Transistors

open access: yesAdvanced Materials Technologies, EarlyView.
A fully lithography‐free fabrication strategy for organic electrochemical transistors (OECTs) is developed, eliminating the need for photolithography and other cleanroom‐based processes. By combining a laser‐cut polymer mask with a dual‐layer tape process, the proposed strategy enables simple and accessible fabrication, facilitating rapid OECT ...

Disentangling Optical Transport Regimes in Hyperuniform Photonic Materials Via Transverse Beam Spreading

open access: yesAdvanced Optical Materials, EarlyView.
Light in a disordered dielectric slab spreads, confines, or is blocked depending on the transport regime. Studying the transverse spreading of a focused beam at the output face identifies diffusion, Anderson localization, and photonic bandgaps, and yields the localization length from a single slab thickness.

Terahertz Phase Inversion via Field‐Free Spin‐Orbit Torque Switching in an Antenna‐Integrated Spintronic Heterostructure

open access: yesAdvanced Optical Materials, EarlyView.
This work demonstrates fast electrical control of the phase of broadband terahertz pulses using a field‐free spintronic emitter. An antenna‐integrated Ta/CoFeB/Pt heterostructure switches its magnetization through spin‐orbit torque with 1 μs$\umu{\rm s}$ electrical pulses, producing complete π$\pi$‐phase inversion without external magnetic fields ...

Molecular Appendix Adjusted Architectural Propagations of Red‐Light Controlled Macroscopic Photoactuating Performances

open access: yesAdvanced Robotics Research, EarlyView.
Amphiphilic chloroazobenzenes, bearing different amino acids as end groups alanine, phenylalanine, and valine, exhibit excellent photoisomerizations. Varying structures of three amino acid groups participate in supramolecular formations and therefore photoinduced morphological transformations via adjusting intermolecular interactions. These interaction

Technical Feasibility Study of Autonomous Field Robot‐Based on‐the‐go Assessment of Soil Nutrients Using Ion‐Sensitive Field‐Effect Transistors

open access: yesAdvanced Robotics Research, EarlyView.
Autonomous field robots equipped with ISFET‐based sensors enable rapid, spatially resolved soil nutrient analysis directly in the field. An automated system based on the BoniRob platform is presented for standardized on‐site extraction and measurement of key macronutrients and soil pH.
