Cnoga's breakthrough technology is based on four Light Emitting Diodes (LEDs) within the finger compartment that shines a discrete wavelength from visual light to infrared light, sensing in the continuous spectrum ranging from 600nm – 1150nm, through the fingertip. As the light wave passes through the fingertip, tissue and blood capillaries, some of the light is absorbed and in turn, the light signal is changed. The light wave is then projected on to the camera. The image sensor detects real time changes of the tissue color and the signal is passed on to a processor were Cnoga advance algorithm compute bio parameters.
