We developed the SEIKO PULSE GRAPH which is a pulse rate training tool for runners. In pulse rate training, the strength controlled by the pulse rate instead of the speed. The PULSE GRAPH helps the training by measuring pulse rate all the time. Organization of PULSE GRAPH and the new technology for measuring pulse rate are explained as follows: The blue sensor catches pulse waves in a high S/N ratio. Although pulse waves have motional noise caused by running, a twin FFT system separates the pulse signal from the motional noise. In the present paper the sensor part is described mainly.
