摘要
Finger-tip blood vessel pulsation (FTP) with a capillary blood vessel pressure of few milligrams was accurately detected using the CoSiB amorphous wire stress-impedance (SI) sensor which shows the giant strain-gauge factor of about 4000. The incisura in a FTP waveform is clearly observed for young aged subjects, while the incisura slightly appeared in a FTP waveform for elder subjects after proper sports. The blood vessel pulsation speed is measured between the elbow and the wrist V-ew, and also between the wrist and the finger-tip V-wf, and found that V-ew is faster than V-wf. The FTP sensing will be useful for diagnosis of the circulatory system and the health state.
