Scientists from the National University of Singapore and Tsinghua University have developed a new biosensor that can monitor the condition of drivers and pilots. It has been built into the seat belt. The new sensor is designed to cope with problems caused by vibrations in vehicles. It uses special materials and conductive filaments that help it pick up biosignals even through clothing. The bio-sensor is able to monitor heartbeat and breathing without contact with the body. Studies have shown that the device works successfully in traffic conditions. During testing in an airplane simulator and in real cars, the researchers confirmed the high efficiency of the sensor. It successfully detected cardiopulmonary signals for 1.5 hours. In addition, the biosensor demonstrated its effectiveness in tracking the subjects' heart rate during sleep and wakefulness in a simulator. This opens up the potential for continuous monitoring of physiologic parameters under challenging conditions. In the future, scientists plan to improve the sensor and test it in additional scenarios
