Researchers at Georgia Institute of Technology (Atlanta, GA) found a new way to give robots a sense of touch. In a paper published in the April edition of the International Journal of Robotics Research, scientists describe a robot arm that was able to 'touch' objects when used in conjunction with electronic vision.
Based on a cell phone camera, electrical and bioengineers at the University of California Los Angeles (UCLA) have developed a technology that can capture images from a fluorescent microscope and flow cytometer. Among other applications, the new device is capable of performing medical diagnostics.
Antimicrobial copper surfaces can reduce the number of hospital-acquired infections (HAIs) by 58% as compared with touch surfaces that do not use copper, according to a new study. The study also found that antimicrobial copper can continuously kill 83% of bacteria that cause HAIs within two hours, including antibiotic-resistant strains.

While hydrophilic formulations are mature technologies that have been around for approximately three decades, they are still being reformulated to achieve a variety of different lubricious attributes. And while antimicrobial coatings—especially those based on the use of ionic silver—are commonly used in the medical device community, they still face a host of challenges. Meeting those challenges will be a major focus of medical device design and development efforts in the years to come.
With each passing year, combination products are growing in importance. However, because they represent a marriage between traditionally discrete technology and market sectors—the medical device and pharmaceutical industries—designing, characterizing, testing, and manufacturing combination products poses a range of unique engineering challenges.
Short of recalls, layoffs, patent suits, tax hikes, and big-ticket mergers and acquisitions, the medical device industry and its myriad products do not generally elicit much media attention—particularly on prime-time TV. But NICO Corp.
Purdue researchers have shown theoretically how to control or eliminate dendrite formation in lithium-ion batteries. Dendrites can cause an internal short circuit, resulting in battery failure and possible fire.
