Patent ID: 11766248

Abstract:
An electronic system for determining a time of the temperature nadir of a female human during the menstrual cycle comprises a wearable device (1) that includes a first sensor system (104), configured to determine a temperature of the female human, and a second sensor system (101, 102, 103), configured to determine one or more further physiological parameters of the female human. The electronic system further comprises a processor (13, 30, 40), configured to determine a detected starting point of the fertility phase of the female human, using the one or more further physiological parameters of the female human. The processor (13, 30, 40) is further configured to detect the temperature nadir as a temporary decrease in the temperature, using the detected starting point of the fertility phase of the female human. The time of the temperature nadir is used as an indicator of the time of ovulation and peak oestrogen level.
