AI Technical Summary
When measuring biological data, existing smart wearable devices capture less emitted light from the photodetector assembly, especially when the light is incident vertically or when water enters the target area, leading to inaccurate data detection.
A biological data detection device was designed, which uses a light-transmitting area and a hollow channel on the back of the shell to allow incident light to be directed at the skin at an angle. Combined with a ring structure and a reflective coating, it prevents external light sources and water from entering and enhances friction.
The photodetector assembly's ability to capture emitted light has been improved, preventing interference from external light sources and water, enhancing the friction between the device and the skin, and ensuring accurate measurement of biological data.
