AI Technical Summary
Existing smart ring-type wearable devices for blood oxygen detection suffer from problems such as complex light source architecture, limited detection accuracy, and high production costs. In particular, the multi-light source design leads to problems such as large device size, high hardware failure rate, low production yield, and high power consumption.
The MicroLED light-emitting chip adopts a single-chip dual-conversion-layer structure to achieve synchronous emission of red and infrared light. Combined with a stacked photodetector, the original light is converted into red and infrared light through red and infrared quantum dot layers, and crosstalk-free photoelectric signal acquisition is achieved through lattice-matched bonding layers and independent electrode structures.
It achieves simultaneous transmission and reception of red and infrared light, reduces device size and hardware complexity, improves detection accuracy and signal-to-noise ratio, simplifies production processes, reduces costs and power consumption, and enhances the user's detection experience.
