Subjects will participate in a study measuring a single set of paired values. In this case, measurements will take roughly 2-30 minutes to complete, and will involve: 1) attaching the sensor on the subject; 2) attaching one or more reference devices to the subject; 3) making measurements with both the sensor and reference device, either simultaneously or sequentially; and 4) collecting and analyzing the paired value.
Subjects will be measured with both a sensor and a reference device
