Seoul National University College of Engineering announced that Professor Sung-Hoon Ahn's team from the Department of Mechanical Engineering has developed a novel auditory technology that allows the recognition of human positions using only a single microphone. This technology facilitates sound-based interaction between humans and robots, even in noisy factory environments.
The research team has successfully implemented the world's first 3D auditory sensor that "sees space with ears" through sound source localization and acoustic communication technologies.
The research findings were published on January 27 in the international journal Robotics and Computer-Integrated Manufacturing.
How can additive manufacturing and metamaterials improve healthcare for aging populations? In a review published in the International Journal of Extreme Manufacturing, researchers examine how 3D printing technologies—particularly laser powder bed fusion and vat photopolymerization—are used to create personalized implants and tissue models using metals, polymers, and even living cells. Their work highlights the role of bioinspired lattice structures and mechanical metamaterials in addressing age-related biomedical challenges and advancing the future of regenerative medicine.
During embryonic development, thousands of cells divide and move as one. Understanding the mechanisms that coordinate this collective behavior remains a significant challenge in biology and the physics of living systems. Researchers from UC San Diego have discovered that avian embryos control their size and shape using modular, independent physical mechanisms. This work may help develop strategies for engineering synthetic biomaterials.
A team led by Rutgers University-New Brunswick engineers has developed a portable device capable of detecting rare genetic mutations from a single drop of blood.
The instrument, described in a study published in Communications Engineering of the Nature Publishing Group, was shown in lab experiments to quickly and accurately test for a genetic condition called hereditary transthyretin amyloidosis, which can cause heart problems.
