US-based technology and computer services company IBM has developed a small sensor unit that can be attached to a person's nails to monitor the effectiveness of drugs used to treat symptoms of Parkinson's disease and other conditions. diseases.
The new device, which works with a computer program to analyze data, measures the tendency of the finger when a person tries to hang on to something. .
TechCrunch, a technology specialist, said the sensor unit could also be installed on the patient's skin to monitor body movements and health status of muscles and nerves.
Researchers at the American company said that the sensors installed on the skin could pose many problems, including the infection of the patient by a microbial. They decided to rely on the data obtained via the movement of the nails.
The movement of the nails being very simple, the sensor used must be very sensitive to movement.
The change in position of the nails, be it trend or movement, is stereotypical when we use it to snag something and grab it or even when we hold or hold our finger, say researchers from the American society.
The researchers said the change was in an area less than 10 microns and could not be observed with the naked eye.
However, it can be monitored by sensors.
The diameter of normal human hair ranges from 50 to 100 microns, while the size of red blood cells is less than 10 microns.
