Pulse Rate
Range: 30 - 220 bpm
Resolution: 0.01 bpm
Accuracy: 3 bpm A
rms
PRV - RMSSD
Typical range: 0 - 300 ms
Resolution: 0.01 ms
Accuracy: 98% of positive agreement, with respect to the
ECG. Absolute relative error < 10%. The comparison was
made on recordings of healthy subjects in still conditions.
Respiration Rate
Range: 4 - 60 rpm
Resolution: 1 rpm
Accuracy: 3 rpm A

Temperature
Range: 0ºC - +50ºC
Resolution: 0.1ºC
Accuracy: ± 0.1ºC within 30.0ºC - 45.0ºC range
ElectroDermal Activity
Range: 0.01 μSiemens – 100 μSiemens.
Resolution: 1 digit ~ 900 pSiemens.
Rest Detection
Range: 0 - 400 (0-99: wake epoch; 100-299: rest epoch;
300-399: rest interruption epoch; 400: for future use)
Accuracy: The Rest detection algorithm did not miss any of
the 46 PSG-derived sleep periods (Sensitivity = 100%). On
average, the Rest detection algorithm detected an earlier
sleep onset and a later sleep offset, with an overall longer
sleep period duration compared to PSG.

rms
A
RMS
accuracy is a statistical calculation of the difference between device measurements and reference
measurements. Approximately two-thirds of the device measurements fall within +/- A
RMS
of the reference
measurement.
