Wearable computing device having a biometric sensor electrode positioned on a display screen cover and operable as an antenna

A wearable computing device comprising:

• a housing;
• a printed circuit board at least partially disposed within the housing;
• a display screen electrically coupled to the printed circuit board;
• a cover positioned on the display screen, the cover comprising a top surface and a bottom surface, the bottom surface comprising a first electrical contact and a second electrical contact, the first electrical contact and the second electrical contact each electrically connected to the printed circuit board;
• and
• a first biometric sensor electrode and a second biometric sensor electrode, the first biometric sensor electrode and the second biometric sensor electrode spaced apart from one another on the top surface of the cover, the first biometric sensor electrode wrapping around a first portion of a periphery of the cover and connected to the first electrical contact, the second biometric sensor electrode wrapping around a second portion of the periphery of the cover and connected to the second electrical contact, at least one of the first biometric sensor electrode or the second biometric sensor electrode having one or more portions that include a conductive material capable of carrying a radio frequency current such that at least one of the first biometric sensor electrode or the second biometric sensor electrode are operable as a radio frequency antenna.
