Very similar to the "check engine" light in your car, scientists are coming up with biosensors which when implanted in your body could signal to you when you're falling sick.
One such medical device that's heading for clinical trials, perhaps later in 2011 is a robotic arm that moves almost like a natural arm.
AdvertisementIt works to a control system that monitors brain activity via a biosensor implanted on the surface of a patient's brain. That project aims to provide better artificial arms for wounded soldiers.
Scientists and medical device regulators are working together to fast track approval of such "biosensors" and devices.
Biosensors monitor changes in the body, often "disease markers" - proteins, genes and other biochemical substances involved in health and disease. And they raise a red flag when things go awry.
The study appeared in the current edition of Chemical and Engineering News (C and EN).
