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.

Method to Revolutionize Battery Recharging

University of Sydney researchers have developed a three-stage method to recharge zinc-air batteries. While zinc-air batteries are currently used as an energy source in hearing aids and some film cameras and railway signal devices, their widespread use has been hindered by the fact that, up until now, recharging them has proved difficult.

Tissue Repair, With a Single Touch

Researchers at The Ohio State University Wexner Medical Center and Ohio State’s College of Engineering have developed a new kind of TNT — a "Tissue Nanotransfection" device that generates specific cell types for treatment within a patient’s own body. The “cuff-link”-sized technology supports the repair or restoration of aging tissue, including organs, blood vessels, and nerve cells. Tech Briefs spoke with one of the TNT’s lead researchers.

Secure 3D Printing: 'Three-Layer' System Protects Parts from Hackers

A 3D printer is essentially a small embedded computer — and can be exploited like one.

Researchers from Georgia Institute of Technology and Rutgers University have developed a “three-layer” way of certifying that an additively manufactured part has not been compromised.

Sprayable Sensing Network Monitors Structural Health

Sprayed sensors were developed that can be networked to render real-time information on the health status of a structure, detecting hidden flaws. The sprayed nanocomposite sensors and an ultrasound actuator are used to actively detect the health condition of the structure to which they are fixed.
