  • APPARATUS AND METHOD FOR MEASURING TRIGLYCERIDE LEVEL
    Publication number: 20240138722
    Abstract: An apparatus for measuring a triglyceride level includes: a sensor including: a plurality of peripheral light sources disposed at a periphery thereof, the plurality of peripheral light sources being configured to emit light toward an object, and a plurality of detectors each disposed at predetermined distances from the respective peripheral light sources of the plurality of peripheral light sources, the plurality of detectors being configured to detect optical signals reflected from or scattered by the object. The apparatus also includes a processor configured to selectively drive the plurality of peripheral light sources to obtain features based on the detected optical signals, and to measure the triglyceride level based on the obtained features.
