I saw an article that Omron Healthcare released a smartwatch that can measure your blood pressure! I think its cool! Here is a short paragraph from the article.
Just before CES 2018 officially begins, Omron Healthcare showed off an unique wearable that has miniaturized the traditional blood pressure monitoring band to something that you can strap on your wrist and still expect the same level of accuracy. This is Omron’s smartwatch and it offers all of what you need from a modern smartwatch like heart rate monitoring, sleep and activity monitoring and now even blood pressure monitoring!
they say it will be announced next month!!! I really think this product is good for my grandparents! Hopefully its cheap
