Abstract
We developed a wireless sphygmograph using a 2.4GHz radio module. The purpose of this system is an evaluation measurement of universal design. This system can measure simultaneously not only a pulse wave meter but the data of another sensor. In this study, we have measured data, sphygmograph and accelerometer, of a running experiment of an electric wheelchair. Measured sphygmograph data were changed to pulse data by derivative2 differentiation. Finally, this system could measure frequency analysis of a change of pulse.
