Embodiment Construction
[0028] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.
[0029] see figure 1 and figure 2 , a biosignal measurement system 100 of the present invention includes an excitation signal source 10 , a biosignal sensor 20 , an environment sensor 30 , an analog front-end sensor 40 and a processor module 50 .
[0030] The processor module 50 controls the excitation signal source 10 to generate an illumination signal to transmit to the skin of the subject and irradiate different areas respectively, so that the light source penetrates the skin and is reflected by the skin of the subject. Specifically, the excitation signal source 10 generates light signals or bioelectric pulse signals to irradiate the skin of the subject.
[0031] The biological signal sensor 20 receives the irradiation signal reflecte...
