Samsung has reportedly showcased its next-generation health-tracking wearable device called the Simband.
Using different wavelengths of light beamed at your skin, Simband will track multiple measures of its wearer's health continuously, such as blood pressure, respiration, heart rate, hydration level, and the amount of carbon dioxide in their blood, Mashable reported.
Samsung's "Voice of the Body" event in San Francisco showed a continuous stream of heartbeat information, seismograph-style, such as one might see on a hospital-grade ECG machine.
A "shuttle battery" will allow users to wear the device 24 hours a day, charging it on your wrist while one sleep.
The still-speculative Simband is designed around a new open software platform called SAMI, for Samsung Architecture Multimodal Interactions.
The company described it as one health platform to rule them all, bringing in information from non-Samsung health trackers too. Samsung says it will release SAMI APIs for developers by the end of the year.
