The world of technology is ever-evolving and new innovations are always being made. Recently, the Chinese brand OPPO made headlines after they unveiled a new patent for PPG (Photo Plethysmo Graphy) sensor technology. This new patent has the potential to revolutionize the way we measure and track physiological parameters such as heart rate and blood oxygen saturation.
PPG sensors are typically found in wearable devices like fitness trackers and smartwatches. This new patent by OPPO suggests the use of two light-emitting assemblies and multiple photoelectric sensors. One of the light-emitting assemblies is further away from the sensors than the other. This new design could be used to create a more accurate and reliable measure of physiological parameters.
The PPG sensors found in most wearable devices today use two methods for detection: transmission and reflection. The OPPO patent utilizes the reflection-mode detection technology. This means that the signals from the light-emitting assemblies are reflected off the user’s skin and detected by the sensors. This could potentially provide a more accurate measure of physiological parameters as the data would be based on the actual physical characteristics of the user’s body.
The potential of this new technology is enormous. With more accurate readings of physiological parameters, we could gain a better understanding of our overall health and well-being. For example, a fitness tracker with a PPG sensor could measure the user’s heart rate more accurately and provide more accurate feedback on their physical activity. This could help users to make better decisions about their health and fitness.
In addition, this new technology could also be used in medical applications. For instance, a PPG sensor could be used to measure the oxygen saturation level of a patient in real-time and provide more accurate feedback on their health. This could potentially help doctors to make better decisions about how to treat a patient and provide more effective care.
It is important to note that this is only a patent and there is no guarantee that OPPO will actually bring this technology to market. However, the potential of this new technology is exciting and could revolutionize the way we measure and track physiological parameters.
At the end of the day, it is uncertain whether this patent will actually come to fruition. However, it is clear that the potential of this new PPG sensor technology is immense and could revolutionize the way we measure and track physiological parameters. For now, all we can do is wait and see what OPPO will do with their revolutionary patent.
