Abstract
A wearable device includes a body unit to be worn on a subject; a light source comprising a plurality of light emitting diodes and configured to emit light to the subject; a sensor comprising a plurality of photodiodes configured to generate electrical signals based on the light returning from the subject, the plurality of photodiodes being divided into a first photodiode (PD) group and a second PD group, and the photodiodes of the first PD group being disposed to face the photodiodes of the second PD group on the body unit; and a controller configured to extract biometric information of the subject based on the electrical signals generated by the plurality of photodiodes.
Claims19
A wearable device comprising:
- a body unit configured to be worn on a subject;
- a light source comprising a plurality of light emitting diodes configured to emit light to the subject;
- a sensor comprising a plurality of photodiodes disposed on the body unit and configured to generate electrical signals based on the light returning from the subject, the plurality of photodiodes being divided into a first photodiode (PD) group and a second PD group, and the photodiodes of the first PD group being disposed to face the photodiodes of the second PD group;
- and
- a controller configured to extract biometric information of the subject based on the electrical signals generated by the plurality of photodiodes, wherein:
- the body unit comprises a first body and a second body which is disposed in parallel to the first body and is spaced apart from the first body;
- and
- each of the plurality of photodiodes has a first end connected to the first body and a second end connected to the second body.
A health monitoring method using a wearable device, the health monitoring method comprising:
- emitting light to a subject by at least one of a plurality of light emitting diodes included in the wearable device;
- receiving the light returning from the subject by a plurality of photodiodes disposed on a body unit of the wearable device, the plurality of photodiodes being divided into a first photodiode (PD) group and a second PD group, the photodiodes in the first PD group being disposed to face the photodiodes of the second PD group, the body unit including a first body and a second body which is disposed in parallel to the first body and is spaced apart from the first body, and each of the plurality of photodiodes having a first end connected to the first body and a second end connected to the second body;
- detecting, using a controller included in the wearable device, electrical signals generated by the plurality of photodiodes based on the received light;
- and
- extracting, using the controller, biometric information of the subject based on the detected electrical signals.
