The temperature sensor used in the femSense patches detects temperature differences of less than 0.1°C and was especially designed to detect the tiny rise in basal body temperature caused by ovulation, which is typically between 0.2°C-0.5°C.
Unlike basic basal thermometers, the patch continuously records temperature measurements, several times per hour. The femSense app will notify you once it has detected your ovulation. No more charting and analyzing!
femSense is a medical product that is made in Austria and CE certified.
