Description

Intelligent wearable device

Technical Field

The utility model belongs to the technical field of the electron, more specifically say, relate to an intelligence wearing equipment.

Background

Along with the development of technique and the improvement of life demand, at present, the electronic product is dressed to intelligence such as intelligence wrist-watch, bracelet more and more appears in daily life, and intelligence wearing equipment such as intelligence wrist-watch, intelligence bracelet has the function that traditional wrist-watch did not have, for example functions such as demonstration, communication, broadcast music, online, physiological monitoring. A common method of physiological monitoring currently used in smart wearable devices is PhotoPlethysmoGraphy (PPG).

The distance of photoplethysmography is as follows: since blood is red, it absorbs green and blue light. The user's skin may be illuminated with green light and the amount of green light reflected by the user's skin may be detected as a photodiode. The amount of green light received by the photodiode is related to the amount of blood flowing through the blood vessel of the user. When the user's heart beats, blood flows in the user's blood vessels and green light is more absorbed (i.e., the photodiode receives less green light), while between beats the user's blood vessels absorb less green light due to less blood. Thus, the user's skin may be illuminated by a green light emitting diode and the photodiode configured to receive the amount of green light reflected from the user's skin to detect the user's heart rate. Based on the principle, red light, infrared tubes, blue light and the like can be emitted to the skin of the user for detecting biological signals of blood oxygen, blood pressure and the like of the user.

Some of the light emitted to the user will penetrate the skin of the user and be reflected back to the photoelectric sensor after being absorbed by the blood of the user, and the light signal will be related to the heartbeat of the user and will exhibit wave property, which is a pulsating component (AC component) in the reflected signal; another part will be reflected directly by the user's skin back to the photosensor and this part of the light signal will not exhibit fluctuations, being the non-pulsating component (DC component) of the reflected signal. There will be more noise in the PPG detection signal due to the user's motion, user tissue muscle movements, incorrect wearing of the device and the influence of ambient light.

The existing intelligent wearable device generally adopts a single light detector corresponding to a plurality of light-emitting elements, and the single detector is difficult to effectively remove noise in a PPG signal, so that the detection precision of a biological signal of a user is not high.
