Encapsulated Thermoacoustic Projector Based on Free-Standing Carbon Nanotube Film
Technical Summary: There are promising applications for thermophones in high power sonar arrays, flexible loudspeakers, and noise cancellation devices. Transparent CNT sheets have the density of air, the electrical conductivity of metals, and the flexibility to fit to any curved surface. Thermoacoustic (TA) sound generation results from temperature...

Twistron Mechanical Energy Harvesters
Mechanical energy harvesters are needed for diverse applications, including self-powered wireless sensors, structural and human health monitoring systems, automotive technologies, and the extraction of energy from ocean waves. Until now, few harvesters have been flexible enough to be used as yarns in textiles, and the performance of such yarns has been...

Intelligent Textiles Prepared from Nanofiber Yarns and Polymer Fiber Actuators
While there has always been a desire for smart textiles, including fabrics which adapt depending on environmental stimuli, it has yet to be effectively accomplished due to the lack of suitable materials. These polymer fiber actuators have enabled the creation of fabrics that can reversibly change properties such as porosity, shape, color and texture....

Sheath-Core Fibers for Superelastic Electronics, Sensors, and Muscles
Summary:From fitness trackers to smart clothing, wearables are in high demand. Researchers at UT Dallas have invented a new class of elastic wires that can be woven into clothing or made into super-stretchy charger cords. Lighter-than-air, electrically conductive sheets of tiny carbon nanotubes are wrapped around a long rubber core to create conducting...

Biscrolling Nanopowders and Carbon Nanotube Sheets into Fibers, Yarns and Textiles
Non-Confidential Description:The technology is the first known method to spin biscrolled fibers/yarns from nanopowder materials using carbon nanotube (CNT) sheets as the host. Nanopowder materials (nanoparticles, nanofibers) are loaded onto the CNT sheets to form bi-layered sheets, which are then scrolled into fibers. A key advantage of this technology...

Electrolyte-Free Charge Injection Tuning of Carbon Nanotube Sheets – Offering Novel Supercapacitor Technology
This invention utilizes bulk material property modification via hole or electron injection into conducting and porous materials including but not limited to carbon nanotubes. Bulk carbon nanotube (CNT) assemblies (sheets, rods, etc) can be charged electrochemically in an electrolyte bath. After the CNT sheet is charged (positively or negatively) in...

Fuel-Powered Artificial Muscles
These inventions are new, highly-efficient actuators which can function as artificial muscles. They are 100 times stronger than natural muscles, able to do 100 times greater work per cycle, and produce larger contractions than natural muscles. Developed using nanotechnology, these actuators are powered through two methods that convert the chemical energy...
