Non-invasive biometric sensor based on organic photodetector

A non-invasive blood glucose sensor comprising:

• a light source configured to irradiate near infrared ray light to a body part for measuring a blood glucose concentration;
• an organic photodetector configured to sense the near infrared ray light transmitted through the body part;
• and
• a detector configured to determine the blood glucose concentration based on a light amount of the near infrared ray light sensed by the organic photodetector by using a correlation,
• wherein according to the correlation, the light amount of the near infrared ray light sensed by the organic photodetector is inversely proportional to the blood glucose concentration.

A non-invasive biometric sensor comprising:

• a light source configured to irradiate near infrared ray light to a body part;
• an organic photodetector facing the light source and spaced apart therefrom, the organic photodetector being configured to generate an output signal in response to the light source transmitting a portion of the near infrared ray light through the body part;
• and
• a detector configured to determine biomedical information based on the output signal from the organic photodetector by using a correlation,
• wherein the biomedical information is a blood glucose concentration, and according to the correlation, the output signal from the organic photodetector is inversely proportional to the blood glucose concentration.
