Requirement 1 – Resting Heart Rate (RHR)
- Device must measure resting heart rate
- Range: 61–92 BPM with ±2 BPM accuracy
- RHR varies with menstrual cycle phases
Requirement 2 – Skin Conductance
- Device must measure skin conductance
- Range: 0.05–5 μS
- Reflects sympathetic nervous system activity, which rises before ovulation
Requirement 3 – Basal Skin Temperature
- Device must measure basal skin temperature
- Accuracy: TBD | Location: TBD
- Temperature is typically higher in the luteal phase vs. follicular/ovulatory phases
Requirement 4 – Wearability
