1. An electronic device comprising:
- a touchscreen, wherein the touchscreen includes;
drive lines;
sense lines;
one or more biosensing areas; and
a photoconductive material in the one or more biosensing area, wherein the photoconductive material includes graphene and at least a portion of the drive lines and the sense lines are embedded in the photoconductive material;
a touchscreen engine, wherein when a touchscreen mode is activated, the touchscreen engine is configured to couple with the sense lines and determine a place on the touchscreen where a user touched the touchscreen with a finger; and
a biosensor engine, wherein when a biosensing mode is activated, the biosensor engine is configured to determine biometrics of the user when the user touches at least one of the one or more biosensing areas.

Abstract
Particular embodiments described herein provide for an electronic device that can be configured to include a touchscreen that includes one or more biosensors. The touchscreen can include drive lines, sense lines, a photoconductive material, one or more biosensing areas, a touchscreen engine, and a biosensor engine. In a touchscreen mode, the touchscreen engine can be configured to couple with the sense lines and determine a place on the touchscreen where a user touched. In a biosensing mode, the biosensor engine can be configured to use the drive lines or sense lines and determine biometrics of the user.

8. A method comprising:
-
determining, when a touchscreen mode is activated, a place on a touchscreen where a user touched the touchscreen, wherein the touchscreen includes drive lines, sense lines, a light source, and photoconductive material, wherein the photoconductive material includes graphene and at least a portion of the drive lines and the sense lines are embedded in the photoconductive material, wherein when the touchscreen mode is activated, a touchscreen engine is configured to couple with the sense lines and determine a place on the touchscreen where a user touched the touchscreen; and determining biometrics of the user when the user touches the touchscreen, wherein the biometrics of the user includes photoplethysmogram (PPG) related data. - View Dependent Claims (9, 10, 11)

12. A system for enabling a touchscreen with a biosensor, the system comprising:
-
one or more processors; a touchscreen, wherein the touchscreen includes; drive lines; sense lines; one or more biosensing areas; a photoconductive material in the one or more biosensing area, wherein the photoconductive material includes graphene and at least a portion of the drive lines and the sense lines are embedded in the photoconductive material; and a drive signal source; a touchscreen engine, wherein when a touchscreen mode is activated, the drive signal sources is activated and touchscreen engine is configured to couple with the sense lines and cause at least one of the one or more processors to determine a place on the touchscreen where a user touched the touchscreen with a finger; and a biosensor engine, wherein when a biosensing mode is activated, the drive signal source is deactivated and biosensor engine is configured to cause at least one of the one or more processors to determine biometrics of the user when the user touches at least one of the one or more biosensing areas on the touchscreen. - View Dependent Claims (13, 14, 15, 16, 17)
