New 'e-dermis' brings sense of touch to prosthetic hands


Amputees often experience the sensation of a "phantom limb" – a feeling that a missing body part is still there. That sensory illusion is closer to becoming a reality thanks to a team of engineers at the Johns Hopkins University that has created an electronic skin. When layered on top of prosthetic hands, this e-dermis brings back a real sense of touch through the fingertips.

Low-cost prosthetic foot mimics natural walking


Prosthetic limb technology has advanced by leaps and bounds, giving amputees a range of bionic options. But such high-tech designs can cost tens of thousands of dollars, making them unattainable for many amputees, particularly in developing countries.

Cost, coverage and more drive hearing aid inequality


Hearing loss seems like one of the great equalizers of old age, striking people of all kinds as their ears gradually lose the ability to pick out sounds or hear certain pitches. But a new national study reveals major gaps in whether Americans over age 55 get help for their hearing loss - gaps that vary greatly with age, race, education and income.

New screening tool could help diagnose early cognitive decline in dementia from home


An international team of scientists have developed a new way to screen for age-related cognitive decline at home using a test which asks people to detect sounds and flashes on their laptop or phone. Developed by researchers from Switzerland and the UK2, the study shows that the simple, cost-effective test may be used to help improve early diagnosis of Mild Cognitive Impairment (MCI).
