Abstract: A novel pulse-diagnosis system was proposed in this study
for measuring pulse wave velocities. In contrast with most conventional
mechanical, rigid-type pulse diagnosis instruments such as pressure
transducers and microactuators, a conductive elastic polymer was adopted as
the sensor material. The soft and formability properties of such material
enabled fabricating a flexible pulse diagnosis instrument. In addition, the
flexible design was integrated with a contemporary, wrist-type pulse-wave
acquisition system to ensure stable measurements. Closely related to the
incidence of cardiovascular diseases, pulse wave velocity was analyzed in
applications to verify the feasibility of this system. Regarding signal
processing, the cun, guan, and chi pulse signals
obtained through the data acquisition
device were sent to the LabVIEW platform for reconstructing the pulse
waveforms. Finally, the results of 20 measured samples were compared and
analyzed to evaluate the level of system performance.
