Chinese web giant Baidu and mobile phone maker Xiaomi have ventured into the world of technology-related health products, with both companies announcing smartphone-connected blood pressure monitors, also known as sphygmomanometers. Baidu's product, just announced today and available for pre-order in China for 399 yuan (HK$503) is known as the Mumu BP2 , and was developed in collaboration with Guangzhou-based Mumu, a company that already makes under-the-arm portable blood pressure monitors. The device is scheduled to ship on November 8. Meanwhile, Xiaomi's sphygmomanometer, dubbed the iHealth and created in a partnership with Silicon Valley's iHealth Labs , was released two weeks ago on the company's website for 199 yuan (HK$251). Both devices are designed to track blood pressure, pulse and heart rate on a chart, making recommendations for the user accordingly. But while Xiaomi's iHealth requires a corded phone dock, Baidu claims that its Mumu BP2 is completely wireless, runs on a rechargeable battery and only has two buttons: power and Bluetooth connection. According to Baidu, Mumu BP2 users can even record all of their blood pressure data on the company's cloud network. This new link between China's tech companies and sphygmomanometers may be due to rising interest in internet-connected health products. In late September, Xiaomi announced a US$25 million investment into iHealth Labs, with the iHealth blood pressure monitor as the first result of this arrangement. A World Health Organisation report published one year ago shows hypertension affects over 40 per cent of Chinese adults aged 45 or older, indicating that a potential market for app-connected blood pressure monitors does exist in China.
