Although Microsoft Band Fitness Bracelet has been discontinued and even supported by companion fitness apps and related services, a new patent shows that Microsoft has not given up on the idea of a fitness bracelet. The patent was filed in November 2019 and included in WIPO’s patent library in June 2020, and the patent illustration looks like a successor to Microsoft Band Bracelet.
The patent introduces a new sensing technology that can transmit light to the skin for the collection and analysis of relevant physiological data, which can track blood pressure, per-fight output, vascular endothelial function and heart rate.
The patent illustration also shows that the fitness bracelet is equipped with a photodetector to receive light that hits the skin and generate electrical output. The device supports a temperature regulator and a processor that produces your heartbeat, stroke, and more based on the electrical output. “The height of light passing through the skin depends on the intensity/wavelength of light, the wearer’s skin tone, and other parameters such as device location, underlying tissue heterogeneity, and so on,” Microsoft said in the patent application. “
