Hierarchically buckled sheath-core fibers for superelastic electronics, sensors, and muscles

Buckled Ribbons of GaAs for Flexible Electronics

Giant-stroke, superelastic carbon nanotube aerogel muscles.

Improved electrically powered artificial muscles are needed for generating force, moving objects, and accomplishing work. Carbon nanotube aerogel sheets are the sole component of new artificial muscles that provide giant elongations and elongation rates of 220% and (3.7 x 10(4))% per second, respectively, at operating temperatures from 80 to 1900 kelvin. These solid-state-fabricated sheets are ...

Nanostructures for sensors, electronics, energy and environment

The areas of nanoscale science and technology are rapidly emerging, with a focus on the design, fabrication, and characterization of functional objects on the scale of several nanometers. The implications of the new advances in this field are expected to reach far and wide, spanning a variety of scientific and engineering disciplines. Nanoscale science is growing evermore important on a global ...

Slit-Surface Electrospinning: A Novel Process Developed for High-Throughput Fabrication of Core-Sheath Fibers

In this work, we report on the development of slit-surface electrospinning--a process that co-localizes two solutions along a slit surface to spontaneously emit multiple core-sheath cone-jets at rates of up to 1 L/h. To the best of our knowledge, this is the first time that production of electrospun core-sheath fibers has been scaled to this magnitude. Fibers produced in this study were defect-...
