One example disclosed wearable device (700, 730, 760) includes a first housing portion having a conductive section (701, 731, 761) and a non-conductive section (705, 735, 765). The conductive section (701, 731, 761) is connected to ground. A second housing portion (703, 733, 763) includes a printed circuit board (PCB) (711, 741, 771) with a conductor (715, 745, 775) on the PCB surface (713, 743, 773) positioned beneath the non-conductive section (705, 735, 765). The conductor (715, 745, 775) on the PCB surface (713, 743, 773) and the conductive section (701, 731, 761) form a capacitor of a capacitive sensor. The wearable device (700, 730, 760) may also include a first adhesive layer (717, 747, 777) between a surface of the non-conductive section (705, 735, 765) of the first housing portion and the PCB surface (713, 743, 773). A second adhesive layer (719, 749, 779), coplanar with the first adhesive layer (717, 747, 777), may be applied between a surface of the conductive section (701, 731, 761) of the first housing portion and the PCB surface (713, 743, 773). The first adhesive layer (717, 747, 777), and the second adhesive layer (719, 749, 779) form a water tight seal that prevents liquids from penetrating into at least the second housing portion (703, 733, 763). |
