Vibrating insoles could help prevent falls among seniors

By - October 31, 2014 1 Picture
Falls are the leading cause of death by injury amongst seniors, and those falls are in turn typically caused by poor balance or an irregular gait. Taking things back yet another step, problems with balance and gait are often caused by diminished sensation in the feet. Now, however, a new study indicates that subtly-buzzing insoles may help seniors regain some of that lost sensation, and thus be less likely to fall down. Read More

Glove with vibrating fingertip enhances user's sense of touch

By - August 4, 2011 3 Pictures
Studies have shown that with the right amount of white noise in the background, peoples’ sight, hearing, balance control and sense of touch improve. Utilizing stochastic resonance, which is the principle at work in white noise, researchers at the Georgia Institute of Technology have discovered that the sense of touch can also be improved by applying vibrations to a person’s finger. They have been testing a glove that incorporates a prototype fingertip-buzzing device, that could ultimately lead to products worn by people with nerve damage, or whose jobs require exceptional manual dexterity.

Turning image noise into a good thing

By - April 8, 2010 2 Pictures
Noise in images is generally held to be a bad thing, but engineers from Princeton University have used a nonlinear material to steal energy from image noise to reveal hidden or obscured objects. The engineers see the technology as potentially paving the way for improvements to radar systems, sonograms and stenography offering the possibility of allowing pilots to see through fog and doctors to look inside the human body without surgery Read More
