Nanotube Yarns Generate Electricity When Stretched

Scientists at The University of Texas at Dallas and South Korea’s Hanyang University have developed tiny, high-tech yarns that generate electricity when stretched or twisted. The nanoyarns, constructed from hollow carbon nanotubes, create current when coated with an ionically conducting material — even a simple mixture of table salt and water.

From Seawater to Drinking Water? Nanotubes Upgrade Desalination Efforts

Looking to nature for inspiration, scientists from Lawrence Livermore National Laboratory (LLNL) and Northeastern University have used carbon nanotubes to mimic the water-filtering proteins of the body. The super-thin graphene cylinders improve water desalination efforts and support a new generation of high-flux membranes.

Harmonic Air Motor Offers Very High Efficiency

Currently available air motors have many advantages over electric motors. They are more compact, lighter-weight, instantly reversible without sparking, create no heat buildup, are undamaged by stalling or overloading, and supply extremely broad torque and speed range. Generally available commercial air motors, however, have only 5% to 20% of ideal efficiency.

Robotic Gripper Cleans Up Space Debris

Currently there are about 500,000 pieces of human-made debris in space, orbiting our planet at speeds up to 17,500 miles per hour. This debris poses a threat to satellites, space vehicles, and astronauts aboard those vehicles. However, cleaning up the debris is problematic. For example, suction cups don’t work in a vacuum, and traditional sticky substances like tape are largely useless because the chemicals they rely on can’t withstand extreme temperature swings.

Wireless Magnetic Field Powers Folding Robots

A team of researchers at the Wyss Institute for Biologically Inspired Engineering and the John A. Paulson School of Engineering and Applied Sciences (SEAS) at Harvard University has created battery-free folding robots that are capable of complex, repeatable movements powered and controlled through a wireless magnetic field. The system requires only basic, passive electronic components on the robot to deliver an electric current, and the structure of the robot itself takes care of the rest.

Sound-Off: What is Live Tooling?

When features need to be removed from a product, manufacturers often use a subtractive process known as CNC machining. In a Tech Briefs presentation last week, engineer Tony Holtz made a case for a more “Rapid” method.

Turning Homes into Power Stations

A new solar project, called SUNRISE, will develop printed photovoltaic cells and new manufacturing processes that can be used to construct solar energy products in India. These will then be integrated into buildings in five villages, allowing them to harness solar power to provide their own energy and run off-grid. The plan is to encourage local industries to manufacture affordable prefabricated buildings that can generate, store, and release their own power.
