Flexible Loudspeaker Made of Nanowires Will Stick to Your Skin and Play Music

Researchers in South Korea made a tiny loudspeaker, and then used it to play a violin concerto By Dexter Johnson Image: Ulsan National Institute of Science and Technology/Science Advances A variety of nanomaterials have been used over the years in loudspeakers and microphones. Nanoparticles have replaced permanent magnets in loudspeakers and a thin film of carbon nanotubes has done […]

Carbon nanotube yarn taps nerves for electroceutical treatments and diagnostics

(Nanowerk News) Ingested or injected pharmaceuticals can target specific molecules involved in disease processes, but get distributed throughout the body where they can cause unwanted side effects. An approach known as electroceuticals aims to avoid systemic exposure by using small wires to electrically monitor and manipulate individual nerves that control organ function and carry information […]

Physics Charge Smartphones Clothes Made From Carbon Nanotubes

Physicists from the University of Cincinnati will soon be able to charge smartphones using clothes made from carbon nanotubes. With the assistance of their colleagues from the BBC, Wright-Patterson, the experts intend to create a special material, which because of the peculiarities of carbon nanotubes would be exceptionally heat-resistant conducting electricity, and will also differ […]

Scientists fine-tune carbon nanotubes for flexible, fingertip-wearable terahertz imagers

Researchers at Tokyo Institute of Technology have developed flexible terahertz imagers based on chemically “tunable” carbon nanotube materials. The findings expand the scope of terahertz applications to include wrap-around, wearable technologies as well as large-area photonic devices. Carbon nanotubes (CNTs) are beginning to take the electronics world by storm, and now their use in terahertz […]

DexMat Awarded Phase II SBIR – Lightweight CNT Shielded Cables for Space Applications

Abstract: The effects of electromagnetic interactions in electrical systems are of growing concern due to the increasing susceptibility of system components to electromagnetic interference (EMI), use of automated electronic systems, and pollution of the electromagnetic environment with electromagnetic emissions. The effects of EMI can be detrimental to electronic systems utilized in space missions; even small […]

Gamma-ray shielding performance of carbon nanotube film material

This paper aims to explore the shielding potential of light-weight carbon nanotube (CNT) film materials against gamma-ray generated from americium-241 (241Am) and caesium-137 (137Cs). The influence factors of gamma mass attenuation coefficient of CNT film laminates were investigated to reveal structure-property relationship. The results showed that CNT film materials had bigger mass attenuation coefficients than […]

Nano-coating Makes Coaxial Cables Lighter

Rice University scientists replace metal with carbon nanotubes for aerospace use Common coaxial cables could be made 50 percent lighter with a new nanotube-based outer conductor developed by Rice University scientists. The Rice lab of Professor Matteo Pasquali has developed a coating that could replace the tin-coated copper braid that transmits the signal and shields […]

Nanotube Fibers Being Tested as a Way to Restore Electrical Health to Hearts

Rice University, Texas Heart Institute will study soft, conductive fibers’ ability to bridge scar tissue Rice University and Texas Heart Institute researchers are studying the use of soft, flexible fibers made of carbon nanotubes to restore electrical conductivity to damaged heart tissue. With support from the American Heart Association, these institutions will test the fibers’ ability […]
