Abstract

A wearable computing device includes an outer covering defining an outer-most top surface and an outer perimeter and an internal volume defined, at least in part, by an inner surface of the outer covering. The wearable computing device also includes an electronic display and an electronic display module connector arranged within the internal volume. Further, the wearable computing device includes at least one biometric sensor electrode positioned on the outer-most top surface of the outer covering and wrapping around one or more side edges of the outer covering to the internal volume. Moreover, the wearable computing device includes a printed circuit board arranged within the internal volume. In addition, the wearable computing device includes a conductive component electrically connecting the biometric sensor electrode(s) to the printed circuit board through the electronic display module connector.

Dependent claims

A wearable computing device, comprising:

an outer covering defining an outer-most top surface and an outer perimeter;
an internal volume defined, at least in part, by an inner surface of the outer covering;
an electronic display and an electronic display module connector arranged within the internal volume;
at least one biometric sensor electrode positioned on the outer-most top surface of the outer covering and wrapping around one or more side edges of the outer covering to the internal volume;
a printed circuit board arranged within the internal volume;
a conductive component electrically connecting the at least one biometric sensor electrode to the printed circuit board through the electronic display module connector;
and
a contact pad arranged between the conductive component and a top surface of the electronic display,
wherein the at least one biometric sensor electrode wraps around the one or more side edges of the outer covering to the internal volume such that a first end of the conductive component is secured to an end of the at least one biometric sensor electrode and an opposing end of the conductive component is secured directly to one of the printed circuit board or a conductive component in direct contact with the printed circuit board.

A method of assembling a wearable computing device, the method comprising:

providing an outer covering defining an outer-most top surface and an outer perimeter, an inner surface of the outer covering defining an internal volume;
positioning a first portion of at least one biometric sensor electrode on the outer-most top surface of the outer covering and wrapping a second portion of the at least one biometric sensor electrode around one or more side edges of the outer covering such that the second portion is within the internal volume;
placing an electronic display and an electronic display module connector within the internal volume;
arranging a printed circuit board within the internal volume adjacent to the electronic display;
and
electrically connecting the at least one biometric sensor electrode to the printed circuit board through the electronic display module connector via at least one conductive component,
wherein, when the at least one biometric sensor electrode is wrapped around the one or more side edges of the outer covering to the internal volume, electrically connecting the at least one biometric sensor electrode to the printed circuit board through the electronic display module connector via at least one conductive component further comprises securing a first end of the conductive component to an end of the at least one biometric sensor electrode and securing an opposing end of the conductive component directly to one of the printed circuit board or a conductive component in direct contact with the printed circuit board, and
laminating the outer covering, the at least one conductive component, and the at least one biometric sensor electrode together.
