Samsung patents gas sensor that uses light to identify air components

Patent drawing from the official filing.

Samsung describes a system that combines a group of chemical sensors with a light-based optical sensor. The light sensor shines a beam through the air and analyzes the spectrum to predict what gases are present.

Why it mattersThis technology could help electronic devices monitor air quality or detect specific chemical leaks more accurately than chemical sensors alone.

In the filing’s own words

A sensor system includes a first sensor array including a plurality of first sensors having different sensitivities with respect to components of a gas mixture, and a second sensor including a plurality of electrodes configured to emit light, an optical lens configured to collimate the light, and a spectroscope, where the second sensor is configured to generate a prediction value corresponding to the components of the gas mixture.

What exactly they claim (claim 1)

1. A sensor system comprising: a first sensor array comprising a plurality of first sensors having different sensitivities with respect to components of a gas mixture; and a second sensor comprising: a plurality of electrodes configured to emit light; an optical lens configured to collimate the light; and a spectroscope, wherein the second sensor is configured to generate a prediction value corresponding to the components of the gas mixture.
