Title: NON-INVASIVE BLOOD GLUCOSE SENSOR
Abstract:
A non-invasive blood sensor includes a body configured to mate with a tissue surface; a blue light source disposed on the sensor body; and a photodetector disposed on the sensor body at a suitable position for capturing light emanating from the tissue surface after emission from the blue light source, e.g., by one of : transmission, reflection, and transflection. The sensor bodies may further include a green, a red and/or an infrared light source. The light source(s) and photodetector(s) may be supported on a support structure configured to register with a corresponding portion of human anatomy in a predetermined fashion, and support the light sources and photodetectors in a defined spatial relationship. The sensor or an integrated meter may include a controller programmed to receive signals from the photodetector and calculate blood glucose value as function of the signals received from the photodetector after emission by the light source(s).
