It would be worn on the upper arm and would combine two kinds of measurements in one circular design. A small reusable electronic core in the center would use light to measure heart rate and pulse shape. A replaceable ring around it would collect sweat and measure sweat rate, sodium level, and skin temperature. The Bio-skin would be designed to last for three work shifts, while the core would be removed and charged after each 8–12 hour shift. The patch would help a worker notice patterns related to heat, hydration, and physical effort, and provide timely reminders when signs of increasing strain appear.Hugoen
