A smart low power R-R-I heartbeat monitor system with contactless UWB sensor

A heartbeat contactless monitor system with the less burden on human body is an effective solution to support the safety car with monitoring driver's condition. This paper shows the smart low power R-R-I heart monitor system with contactless UWB sensor. The measured R-R-I data in the driving space estimate the condition of autonomic nerves/conic body, and detect the physical condition of the drivers, for example sleepiness. We have adopted the noise filtering and the forecasting algorithm using autonomic parameter for breath and body movement to get the accurate R-R-I. Additionally, three times power reduction compare to the conventional power management technique has been achieved.
