| Abstract: | Nowadays biomedical sensors develop along a painless,integrative and intelligent way,and so does the designed multifunction sensor for blood flow and oxygen saturation detection.Based on advanced technology of laser Doppler and spectrum,it can detect and transform three kinds of human physiology parameters:blood flow,oxygen saturation of pulse and brain.On the othe hand,it applies small and sensitive components;and the distance between light source and signal receiver can be adjusted accurately,which may offer great convenience to medical and physiological research. |
