Abstract

The invention belongs to the electric power electronic technology field and provides a biosensor circuit and intelligent wearable equipment. The circuit comprises a light emitting diode used for emitting light particles, a photoelectric converter comprising a photosensitive receiver tube and a photoelectric transformation module, a current stabilization module and a current control module, whereinthe photosensitive receiver tube is used for receiving the reflected light particles, a first end of the current stabilization module is connected with a cathode of the light emitting diode, an anodeof the light emitting diode is connected with a DC power source, the current control module is connected between a second end of the current stabilization module and the ground, and the current control module is used for controlling the current flowing through the light emitting device for being stable. The biosensor circuit is advantaged in that problems of relatively large measurement errors ofhuman body physiological indexes caused by difficulty in providing the stable constant current and the relatively low signal to noise ratio existing in a biosensor circuit in the prior art can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of power electronics, and in particular relates to a biosensor circuit and an intelligent wearable device. Background technique [0002] With the improvement of people's awareness of their own health, smart wearable devices have been more and more widely used. At present, smart wearable devices acquire and collect various physiological indicators of the human body, such as blood pressure, blood oxygen, pulse, etc., through biosensor circuits. The existing biosensor circuit mainly utilizes the electrical characteristics of the photosensitive device, and its light intensity has a functional relationship with the operating current, and human blood can absorb a small amount of light particles under certain conditions. health status. [0003] Therefore, the existing biosensor circuit has the following problems: when the prior art provides a constant current for the photosensitive device, the pulse sampling meth...
