Background

The photoelectric heart rate sensor is one of the more popular sensors used in intelligent wearable equipment, and is mainly applied to heart rate detection as the name suggests, and the principle of the photoelectric heart rate sensor is that when a light beam with a certain wavelength irradiates the surface of human skin (usually, wrist), part of the light beam enters the skin and returns to a photoelectric receiver after being scattered, and the light is absorbed by the skin and blood in the process, so that the light intensity detected by the receiver is weakened, and the blood volume is pulsated under the action of the heart. When the heart contracts, the maximum light absorption amount of peripheral blood volume is also maximum, the detected light intensity is minimum, and when the heart expands, the detected light intensity is maximum, so that the light intensity received by the light receiver is in periodic change, the change frequency of the light intensity is the same as the heart beating frequency, and the heart rate value is obtained by extracting periodic signals.

However, in the use process of the traditional photoelectric heart rate sensor, since the light-transmitting sheet of the photoelectric heart rate sensor is exposed outside and easily adheres to dust and impurities after the use is finished, the light-transmitting performance of the light-transmitting sheet is affected, and the pulse heart rate acquisition effect is difficult to ensure, so that the photoelectric heart rate sensor is provided.
