Similar to natural muscle fibers, coiled artificial fibers provide a straightforward contraction. However, unlike their recovery from the contracted state initial requires high stress, resulting in almost zero work during full actuation cycle. Herein, self-recoverable fiber was prepared by conformally coating an elastic carbon nanotube (CNT) with very thin liquid crystal elastomer (LCE) sheath. The as-obtained demonstrated excellent properties comprising 56.9% contractile stroke, 1522%/s...
Nanoimprint lithography and physical vapor deposition were combined to fabricate large-area homogeneously patterned SERS-active substrates with tunable surface plasmon resonances. The shift observed was connected the nanotopography since (a) nanoparticles on all investigated shown be chemically structurally similar (b) SERS spectra of analyte essentially identical for samples. In addition, tunability boost effect via optimal coupling between substrate's SPR incident laser line.
We developed a hybrid nanoimprint−soft lithography technique with sub-15 nm resolution. It is capable of patterning both flat and curved substrates. The key component the technology mold, which consists rigid features on an elastic poly(dimethylsiloxane) (PDMS) support. mold was fabricated by imprinting reverse image onto PDMS substrate using UV-curable low-viscosity prepolymer film. Patterns sub-15-nm resolution were faithfully duplicated without applying external pressure. Gratings at 200...

Integrating sense in a thin artificial muscle fiber for environmental adaption and actuation path tracing, as snail tentacle does, is highly needed but still challenging because of the interfacing mismatch between fiber's sensing components. Here, we report an neuromuscular by wrapping carbon nanotube (CNT) core sequence with elastomer layer, nanofiber network, MXene/CNT sheath, achieving ingenious sense-judge-act intelligent system elastic fiber. The CNT/elastomer components provide...
E-beam lithography is a powerful tool for generating nanostructures and fabricating nanodevices with fine features approaching few nanometers in size. However, alternative approaches to conventional spin coating development processes are required optimize the procedure on irregular surfaces. In this review, we summarize state of art nanofabrication substrates using e-beam lithography. To overcome these challenges, unconventional methods have been developed. For instance, polymeric...
Morphing textiles, crafted using electrochemical artificial muscle yarns, boast features such as adaptive structural flexibility, programmable control, low operating voltage, and minimal thermal effect. However, the progression of these textiles is still impeded by challenges in continuous production yarn muscles necessity for proper structure designs that bypass operation extensive electrolyte environments. Herein, a meters-long sheath-core structured carbon nanotube (CNT)/nylon composite...
