“…Different combinations of color attributes can form more than 7.5 million colors, and the number of colors recognizable to the human eye is estimated to be up to 2.7 million ( 1 ). Color recognition plays a very important role in wide fields, such as disease detections ( 2 , 3 ), chemical reaction processes ( 4 , 5 ), environmental protection ( 6 , 7 ), sensing applications ( 8 ), industrial production ( 9 ), etc. In the past few decades, a great number of electronic apparatuses have been developed for color and optical recognition based on photoelectric effects, such as (photoemissive) photomultiplier tube, cooled charge-coupled devices, or the (junction-based) avalanche photodiode for high-sensitivity detection ( 10 ).…”

Color is the mapping of electromagnetic waves of different wavelengths in human vision. The electronic color recognition system currently in use is mainly based on the photoelectric effect. Here, we demonstrate a color materials’ recognition system based on photothermoelectric effects. The system uses a microfabricated thermoelectric generator (TEG) as a platform, which is covered with dye-colored fabric pieces or structure-colored laser-patterned metal sheets. Under light irradiation, the fabrics/metals selectively absorb light and convert it into heat, which flows through the underlying TEG arrays and then converted into electrical signal output to realize the distinction of color and materials. This previously unidentified high-sensitivity TEG detection method provides a potential approach for precise color materials’ detection over wide areas and may help understand the mechanism of bionic color recognition.
