The article describes new medical devices using artificial intelligence, presented at the CES trade show in Las Vegas, that promise to improve health and prevention. A smart scale that scans your feet and tracks multiple indicators of heart health is being introduced. Another example is an egg-shaped hormone tracker aimed at women's reproductive health. Experts warn that these devices are often not regulated enough. They express concern about the accuracy of measurements and the interpretation of results without the supervision of a doctor. They also point to the risk of incorrect health decisions if people rely only on the outputs of these devices. Problems with the protection of sensitive health data collected and evaluated by these devices are also discussed.
