the traditional home pregnancy test could soon be obsolete, scientists have said as they announced a new smartwatch system that alerts women when they conceive.
Trials in Switzerland have allowed researchers to identify for the first time a package of minute physiological changes, detectable by existing hardware, that take place when pregnancy starts.
They are now building an algorithm which learns the individual wearer’s personal characteristics so it can not only signal the start of a pregnancy but also highlight the best windows in which to try for a baby.
The technology promises to allow women hoping to conceive to do away with the morning ritual of a home pregnancy test, which assesses levels of human Chorionic Gonadotropin in urine.
The team behind the Ava bracelet, which is expected to cost around £200, plan to begin real-world tests of the system before the end of the year.
