Functionality of the Pulse Oximeter and Accelerometer Portions of a Novel Wearable Device

The purpose of this study is to asses the function of an oxygen sensor and the movement sensor in a novel device prototype.

After informing the patient about the study and the potential risk. The patient is asked to wear a prototype of a novel device to sense oxygen levels and movement for the duration of the visit. The day of the enrolment is when the visit will be completed. The patient is required to complete an overnight sleep test (no more than 15 hrs) with the prototype device worn on their index finger and wrist.
