Abstract: A system for measuring at least one physiological parameter includes a wearable device configured to be secured to a subject's foot and a camera configured to captures images of the subject. An electronic device may be in communication with the system and can display information relating to physiological data and/or images collected by the system.

Abstract: A system for measuring at least one physiological parameter includes a wearable device configured to be secured to a subject’s foot and a sensor component that is removably securable to the wearable device. The wearable device includes a base configured to contact a bottom of the subject’s foot, a wall extending outward from the base and configured to surround a heel of the subject’s foot, and a sensor component that is removably securable to the wearable device. The sensor component includes a sensor hub configured to be removably secured to the wearable device, a sensor strap configured to be wrapped around the subject’s foot and secured to the wearable device, an emitter configured to emit optical radiation into tissue of the subject’s foot, and one or more detectors configured to detect at least a portion of the emitted optical radiation after passing through the tissue.

Abstract: A pulse oximetry system for measuring at least one physiological parameter includes a wearable device configured to be secured to a subject's foot, a sensor hub that is removably securable to the wearable device, and a sensor strap connected to the sensor hub and configured to be wrapped around the subject's foot and secured to the wearable device. In some implementations, the wearable device is configured such that the cavity is positioned adjacent a bottom portion of the subject's foot. The system further includes one or more emitters arranged within the sensor hub and configured to face toward said bottom portion of the subject's foot and one or more detectors arranged within the sensor strap and configured to be positioned adjacent a top portion of the subject's foot.

Abstract: A pulse oximetry system includes a wrist portion configured for placement on a wrist of a subject, the wrist portion having a first component and a second component configured to removably secure to one another. The wrist portion can include emitter(s) and detector(s) operably positioned by the wrist portion. In some implementations, the pulse oximetry system further includes a ring member configured to secure around the subject's finger and operably position emitter(s) and detector(s) and a cable connected to the wrist portion in electrical communication with the emitter(s) and the detector(s) of the ring member and configured to transmit the signal(s) from the detector(s) to the wrist portion. The system includes a battery and hardware processor(s) configured to receive and process signal(s) outputted by the detector(s) to determine physiological parameter(s) of the subject.
