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.

Sound-Off: How Does ‘Cold Forming’ Impact a Part?

The manufacturing process of "cold forming" applies force to a metal as it is staged in a die. The technology, used originally in the early 1900s to create artillery shells, supports the creation of a variety of sophisticated, small parts, including fasteners, pins, and screws. But how do the residual stresses caused by the process affect the life of the part?

Sound-Off: How Do Collaborative Robots Spot Human Operators?

In a “speed and separation” manufacturing scenario, a safe distance must be maintained between a collaborative robot and a human operator. When the gap reaches below a specific threshold, the cobot then initiates a monitored stop. But how does the robot “see” the human?

Researcher Sees the Power of Solar Glasses

New eyeglasses from Germany’s Karlsruhe Institute of Technology generate solar power. Featuring semitransparent organic solar cells, the eyewear powers a microprocessor and two small displays integrated into the solar glasses’ temples. In a Tech Briefs Q&A, one KIT researcher explains why the proof-of-concept is the first step to even smarter devices.

Study points way to better implantable medical devices

Medical devices implanted in the body for drug delivery, sensing, or tissue regeneration usually come under fire from the host's immune system. Defense cells work to isolate material they consider foreign to the body, building up a wall of dense scar tissue around the devices, which eventually become unable to perform their functions.
