Abstract
The present technology provides a color-sensing device that includes an electrically-conductive substrate and a bulk heterojunction (BHJ) polymer layer formed on the substrate. The color-sensing device is configured to detect a first color of two colors and produce a first electrical signal that includes a first current response indicating detection of the first color. The color-sensing device is further configured to detect a second color of the two colors and produce a second electrical signal that includes a second current response indicating detection of the second color.
Claims20
An apparatus for sensing multiple colors, the apparatus comprising:
- an electrically-conductive substrate;
- and
- a bulk heterojunction (BHJ) polymer layer formed on the electrically-conductive substrate, wherein the BHJ polymer layer is configured to:
- produce a first current response responsive to reception of a first color of two colors;
- and
- produce second current response responsive to reception of a second color of the two colors;
- and
- wherein the apparatus is configured to:
- produce a first electrical signal corresponding to the first current response indicating detection of the first color;
- and
- produce a second electrical signal corresponding to the second current response indicating detection of the second color.
A method of multiple sensing colors using a color-sensing device, the method comprising:
- receiving light at a bulk heterojunction (BHJ) polymer layer formed on an electrically-conductive substrate, wherein the color sensing device is configured to:
- detect a first of two colors and produce a first electrical signal indicating detection of the first color;
- and
- detect a second of the two colors and produce a second electrical signal indicating detection of the second color;
- producing, by the BHJ polymer layer, a current response to the received light, wherein the current response is indicative of one of the two colors, and wherein the BHJ polymer layer is configured to produce unique current responses for each of the two colors;
- and
- in response to producing the current response, conveying at least one of the first electrical signal or the second electrical signal.
