Abstract
Disclosed is a non-invasive biometric sensor including a light source, an organic photodetector, and a detector. The light source is configured to irradiate light in a desired (and/or alternatively predetermined) wavelength range to a body part. The organic photodetector is configured to sense the light in the desired (and/or alternatively predetermined) wavelength range in response to the light in the desired (and/or alternatively predetermined) range being transmitted through the body part. The detector is configured to determine biomedical information of the body part based on an amount of the light sensed by the organic photodetector.
