Abstract

Systems and methods are disclosed for smart rings having compact form factors. In one embodiment, a wearable device can include a printed circuit board having a first portion and a second portion, a first light emitting diode (LED) disposed on the first portion of the printed circuit board, the first LED configured to output green light, a second LED disposed on the first portion of the printed circuit board, a third LED disposed on the second portion of the printed circuit board, the third LED configured to output red light, and a photodiode disposed on the first portion of the printed circuit board, the photodiode configured to detect light output from at least one of the first LED, the second LED, or the third LED. The first LED, the second LED, and the third LED are directly attached to the printed circuit board.

Dependent claims

A finger-worn wearable ring device comprising:

a housing having an interior diameter between 12 mm and 24 mm and an exterior diameter between 18 mm and 30 mm for at least a portion of the finger-worn wearable ring device, the housing comprising:
a curved battery;
a printed circuit board comprising a first rigid portion, a second rigid portion, a third rigid portion, a first flexible portion separating the second rigid portion from the first rigid portion, and a second flexible portion separating the third rigid portion from the second rigid portion;
a first light emitting diode (LED) disposed on the first rigid portion of the printed circuit board, the first LED configured to output green light;
a second LED disposed on the first rigid portion of the printed circuit board, the second LED configured to output yellow light;
a third LED disposed on the third rigid portion of the printed circuit board, the third LED configured to output red light;
and
a first photodiode disposed on the first rigid portion of the printed circuit board, the first photodiode configured to detect light output from at least one of the first LED, the second LED, or the third LED;
wherein the first LED, the second LED, and the third LED are directly attached to the printed circuit board.
