Deformable Joule Heating Electrode Based on Hybrid Layers of Silver Nanowires and Carbon Nanotubes and its Application in a Refreshable Multi‐Cell Braille Display Open
Joule heating electrodes (JHEs) are required for thermal actuation systems. A highly stretchable, patternable, and low‐voltage operating JHE based on hybrid layers of silver nanowires and carbon nanotubes are reported. The conductive layer…

Theoretical and experimental investigation of chalcogenide suspended waveguide gas sensor Open
To address the issues of low ratio of evanescent field ( γ ) and high reflectivity between waveguide cross‐section and gas for the mid‐infrared waveguide sensors, we propose a chalcogenide (ChG) suspended waveguide with Ge 28 Sb 12 Se 60 a…

Hybrid Fabrication of Prestrain‐Locked Acrylic Dielectric Elastomer Thin Films and Multilayer Stacks Open
Dielectric elastomers based on commercial acrylic dielectric elastomers (VHB adhesive films) are widely investigated for soft actuators due to their large electrically driven actuation strain and high work density. However, the VHB films r…

Post-functionalization and Mechanical Properties of Poly(lactide-cyclohexadiene oxide) Block Copolymers Open
A series of lactide (LA) and cyclohexadiene oxide (CHDO) multiblock copolymers was synthesized using a redox switchable complex, (salfen)Zr(OiPr)2 (salfen = N,N’-bis(2,4-di-tert-butylphenoxy)-1,1’-ferrocenediimine), with LA being polymeriz…

A unimorph nanocomposite dielectric elastomer for large out-of-plane actuation Open
Dielectric elastomer actuators (DEAs) feature large, reversible in-plane deformation, and stacked DEA layers are used to produce large strokes in the thickness dimension. We introduce an electrophoretic process to concentrate boron nitride…

A 2D refreshable Braille display based on a stiffness variable polymer and pneumatic actuation Open
Visual impairments limit a person's ability to process information such as obstacles, environments, reading and especially multimedia content (e.g., photographs and videos). In this work, we present the design and operating mechanism of Br…

Theoretical study of microcavity-enhanced absorption spectroscopy for mid-infrared methane detection using a chalcogenide/silica-on-fluoride horizontal slot-waveguide racetrack resonator Open
The reported chalcogenide (ChG) rectangular waveguide sensors with a small evanescent field need a large waveguide length to obtain an enhanced light-gas interaction effect. To make such sensors compact and improve the light-gas interactio…
