Opportunities for Prismless Attenuated Total Reflection in Multiple Frequency Ranges

Photonics
Attenuated total reflection (ATR) has long relied on a familiar trio—prism, metal film, and substrate—to unlock insights into material properties. In this work, we demonstrate the possibility and limitations of a prismless ATR system that utilizes the ...

Inkjet printing of dielectric layers with high relative permittivity for digital microfluidics

, 2022
Paper 1163708, 5 S.Digital microfluidics (DMF) is an emerging technology for liquid-handling of picoliter-to microliter-sized droplets. It enables individual control over droplets by applying electrical fields to an array of electrodes.

Fiber‐reinforced Liquid Metal Composites With Automated Circuit Fabrication for Structurally‐Integrated Power Transfer

Advanced Functional Materials, EarlyView.
Fiber‐reinforced liquid metal composites (FibRe LMCs) are introduced that combine GPa‐scale structural performance with digitally programmable electrical conductivity. Through automated CNC activation, conductive pathways and wireless power transfer circuits are fabricated directly within load‐bearing composites, enabling structurally integrated ...

Imaging the Thickness‐Dependent Formation of Schottky Barriers in Metal–Semiconductor van der Waals Heterostructures

Advanced Functional Materials, EarlyView.
Using nanobeam photoemission, we demonstrate imaging of the in‐plane and out‐of‐plane electric field landscape within a metal–semiconductor van der Waals heterostructure. We provide evidence for Schottky barrier formation that depends on the semiconductor thickness. ABSTRACT Achieving high‐performance optoelectronic devices based on two‐dimensional van

Dielectric properties of CaCu3Ti4O12 based multiphased ceramics [PDF]

, 2006
A “soft chemistry” method, the coprecipitation, has been used to synthesize the perovskite CaCu3Ti4O12 (CCT). Three main types of materials were obtained for both powders and sintered ceramics: a monophased consisting of the pure CCT phase, a biphased ...

Self‐Assembled Lipids as Soft Dielectrics

Advanced Functional Materials, EarlyView.
Self‐assembled lipid bilayers serve as soft dielectric materials for ultrathin electronics. Using liquid‐metal parallel‐plate junctions, the capacitance and dielectric breakdown of dehydrated lipid films are characterized. Dielectric behavior is controlled by lipid molecular structure, cholesterol content, and assembly conditions, providing molecular ...

Design and Characterization of a Two‐Dimensional Soft Array Based on Cooperative Dielectric Elastomer Actuators

Advanced Functional Materials, EarlyView.
A fully polymeric two‐dimensional array of Dielectric Elastomers enables self‐sensing, cooperative actuation, and large‐stroke operation in a DE‐based autonomous conveyor. Based only on voltage and current measurements at actuator level, the system detects the presence of a ball and subsequently drives it toward a target position.
