Robotic Glove that 'Feels' Lends a 'Hand' to Relearn Playing Piano After a Stroke

Florida Atlantic University — Thu, 29 Jun 2023 00:00:00 EST

A soft robotic glove is lending a "hand" and providing hope to piano players who have suffered a disabling stroke. Combining flexible tactile sensors, soft actuators and AI, this robotic glove is the first to "feel" the difference between correct and incorrect versions of the same song and to combine these features into a single hand exoskeleton. Unlike prior exoskeletons, this new technology provides precise force and guidance in recovering the fine finger movements required for piano playing and other complex tasks.

How the combination of advanced ultrasound and AI could upgrade cancer diagnostics

National Institute of Biomedical Imaging and Bioengineering — Tue, 06 Jun 2023 09:20:41 EST

Researchers have shown that an automated cancer diagnostic method, which pairs cutting-edge ultrasound techniques with artificial intelligence, can accurately diagnose thyroid cancer, of which there are more than 40,000 new cases every year.

Discovery of Skin Cell Function Could Open Doors to Improved Burn Healing

National Institute of Biomedical Imaging and Bioengineering — Thu, 18 May 2023 15:25:34 EST

Tissue engineering research has shown that a skin cell type could be a new therapeutic target to accelerate the healing of burns and possibly other wounds.

Finger on the pulse of drug delivery

National Institute of Biomedical Imaging and Bioengineering — Thu, 18 May 2023 14:15:21 EST

Researchers from Rice University have created drug-filled microparticles that can be engineered to degrade and release their therapeutic cargo days or weeks after administration. By combining multiple microparticles with different degradation times into a single injection, the researchers could develop a drug formulation that delivers many doses over time.

At-home videos to assess musculoskeletal health

National Institute of Biomedical Imaging and Bioengineering — Fri, 21 Apr 2023 12:55:42 EST

NIH-funded researchers developed an online tool that can analyze self-collected, at-home videos with a smartphone. When deployed in a nationwide study, the tool could predict physical health and osteoarthritis of the knee or hip.

Can bioengineered bacteria make cancer treatments better?

National Institute of Biomedical Imaging and Bioengineering — Mon, 06 Mar 2023 12:45:33 EST

Researchers Unveil New Collection of Human Brain Atlases that Charts the Early Developing Brain in Fine Detail

University of North Carolina Health Care System — Thu, 26 Jan 2023 10:35:56 EST

Human brain atlases can be used by medical professionals to track normative trends over time and to pinpoint crucial aspects of early brain development. By using these atlases, they are able to see what typical structural and functional development looks like, making it easier for them to spot the symptoms of abnormal development, such as attention-deficit / hyperactivity disorder (ADHD), dyslexia, and cerebral palsy.
