Meet the oCare Pro watch: a medical smartwatch that can measure heart rate and blood oxygen on your wrist with medical-grade accuracy. The oCare Pro 100 is built with tBPC’s DOE Lens Reflective PPG Sensor mounted on the bottom. Here is how it works:
The DOE Lens Reflective PPG Sensor consists of two or more light emitting diodes (LEDs) and one or more photodiode light detectors (PDs) located side–by–side on a substrate. Light beams are shone from LEDs through the skin to the arteriolar bed of the tissue. The arteriolar bed absorbs variable amounts of light during the pulsations. Changes in light absorption during the pulsing cycle are measured by the PDs as scattered light that is reflected back from the pulsating arteriolar bed. The ratio of light absorbed is translated into a measurement of heart rate and functional oxygen saturation.
The device has a rechargeable battery and communicates to your smart devices via Bluetooth. It has a 65K color LED display and memory for up to 72 hours of storage.
