Researchers at the University of Washington have developed a new blood-clotting test, which uses a single blood drop as well as a smartphone’s vibration motor and camera.
A plastic attachment holds a tiny cup below the smartphone camera.
This cup contains a small copper particle as well as a chemical that will start the blood clotting process when a person adds blood.
During the test, the vibration motor of the phone shakes the cup while the particle movement is monitored by the camera.
