The sensing system repurposes technology from new bone-conduction microphones, known as Voice Pickup Units (VPUs), which detect only those acoustic waves that travel along the surface of objects. It works in noisy environments, along odd geometries such as toys and arms, and on soft fabrics such as clothing and furniture. Called SAWSense, for the surface acoustic...

SENSOR DETECTS PARKINSON’S DURING SLEEP
The researchers used an artificial intelligence tool to sift through mountains of data from study participants to find patterns that identify the disease and determine severity. “I like to compare our understanding of Parkinson’s to a street lamp in the night; we only get a glimpse of the disease when patients visit clinic. Moreover, the...

Scientists identify sensor underlying mechanical itch stimulus
by The Scripps Research Institute Credit: CC0 Public Domain Scientists at Scripps Research Institute have identified a protein in sensory nerves that works as a key detector of itch—specifically the “mechanical” itch stimulus of crawling insects, wool fibers, or other irritating objects that touch the skin. The discovery, published June 22, 2022, in Nature, is the...

Sensor can detect scarred or fatty liver tissue
by Anne Trafton, Massachusetts Institute of Technology Sensor can detect scarred or fatty liver tissue. MIT engineers have developed a diagnostic tool, based on nuclear magnetic resonance (NMR), that could be used to detect fatty liver disease and liver fibrosis. Credit: Massachusetts Institute of TechnologyAbout 25 percent of the U.S. population suffers from fatty liver...

Home exercise program reduces rate of falling in at-risk seniors
UNIVERSITY OF BRITISH COLUMBIA An in-home exercise program reduced subsequent falls in high-risk seniors by 36 per cent, according the results of a 12-month clinical trial published today in the Journal of the American Medical Association. The study, conducted by UBC faculty of medicine researchers in partnership with the clinical team at the Falls Prevention Clinic at Vancouver General Hospital, found a reduction in fall rate and...

Wearable sensor may cut costs and improve access to biofeedback for people with incomplete paraplegia
A new electromyography biofeedback device that is wearable and connects to novel smartphone games may offer people with incomplete paraplegia a more affordable, self-controllable therapy to enhance their recovery, according to a new study presented this week at the Association of Academic Physiatrists Annual Meeting in Puerto Rico. Electromyography (recording electrical activity of muscles) biofeedback...

Stretchable, Conductive Hydrogel as a Biomedical Sensor
Researchers at King Abdullah University of Science & Technology in Saudi Arabia have developed an electrically conductive hydrogel that can flex, stretch, and self-heal when cut and reattached. The versatile material has potential in a variety of applications including wound healing patches, wearable electronics, and touch-sensitive robotics. The research team developed the new material by...
