The rich blood flow information contained in the pulse is becoming a hot spot in research to detect the pulse and derive the health status of the human cardiovascular system. In this study, PbS quantum dots with a size of 3 nm were synthesized using the hot injection method, and a PbS quantum dot photodetector was constructed on the surface of gold forked fingers electrode through spin coating. Based on the prepared PbS quantum dot photodetector, a data visualization pulse detection system was developed. Using the optoelectronic capacitance pulse wave recording method, we measured the same tester under different exercise states and different testers under the same exercise state, and displayed the measured data on the electronic display screen through circuit processing. The results show that under the illumination of 15.2 μW cm−2 light intensity, its responsivity (R) and light detection rate (D*) are 0.33 A/W and 1.33×1012 Jones under −3 V bias voltage, respectively. When used in the pulse measurement circuit, the system can effectively receive and measure the human pulse signal, proving that the pulse detection system based on the PbS quantum dot photodetector meets the application requirements in terms of sensitivity, stability, and reliability.
