Particular embodiments described herein provide for an electronic device that can be configured to include a plurality of bio-sensing areas, where the bio-sensing areas are located in an area of the electronic device where a user typically comes into contact with the electronic device and a bio-signals engine, where the bio-signals engine can analyze bio signals detected by the bio-sensing areas. These bio-sensing areas can be processed for color, finish and material so as to blend with the electronic device enclosure thereby not degrading the visual appeal.
