Demand for vital sign measurement systems have been increasing. Non-invasive systems are required that it can monitor health status over a prolonged period. Conventional devices can easily measure pulses. However, as the noise due to perspiration is superimposed on the waveform of the pulse, the peak of the pulse becomes unclear, so it is unsuitable for measurement for a long time. In this study, we devised a pulse measurement method that can deal with the above problem. We obtained the acceleration waveform from the carotid artery skin surface, using the acceleration sensor. These waveforms are pulse waves caused by the expansion and contraction of the carotid artery. By the measurement procedure that they devised, six of ten people were able to be measured the pulse. In addition, it became possible to measure the pulse by other four people straightening the neck and attached the sensor to the appropriate position carefully.
