Abstract :
We have proposed the fall detection method using a human pulse as a vital sign, acceleration and angular velocity. For this method, the ubiquitous pulse wave sensor that can measure a human pulse even during fall motion was developed successfully. This pulse wave sensor has the special DC-AC separation amplifier and optical modulator. The pulse wave sensor enables to solve a transient response problem and prevent disturbance by ambient light and measure a human pulse during motion.
