Unobtrusive in-car measurement of physiological signals on the road
Abstract:
This paper presents a system for unobtrusive monitoring of physiological signals of a car driver. It comprises three sensor modalities that conduct measurements through clothes: a Magnetic induction sensor for respiration monitoring, and a reflective Photoplethysmograph as well as a capacitive Electrocardiograph for cardiac monitoring. The sensor system has been attached to the driver seat of a car and a healthy subject was asked to drive through the busy streets of Tokyo while monitored. The raw signals of the unobtrusive Photoplethysmograph and capacitive Electrocardiograph present an overall promising quality. The Magnetic induction sensor worked best with the driver not moving.

Equipments Used To Measure Blood Pressure
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...
