Rutgers University-New Brunswick engineers have developed a smart wristband that wirelessly connects to smartphones for personal health and environmental monitoring. The wristband contains a biosensor that counts particles including blood cells, bacteria, and particulates in the air, exponentially enhancing the current suite of wearables commercially available. Blood samples are taken via pinpricks where they are fed through channels to be collected and counted. The data collected is transmitted using Bluetooth technology to a smartphone app where the data is processed and displayed. Learn more about the smart wristband at Rutgers University-New Brunswick.
