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.

Soft, Stretchy Fabric Sensors Enable Wearable Robots

A highly sensitive, soft, capacitive sensor made of silicone and fabric that moves and flexes with the human body can unobtrusively and accurately detect movement. The technology consists of a thin sheet of silicone sandwiched between two layers of silver-plated, conductive fabric forming a capacitive sensor that registers movement by measuring the change in capacitance.
