Triboelectric nanogenerator for smart traffic monitoring and safety

초록

Traffic monitoring and safety are key for reducing road accidents because the road network is increasingrapidly and becoming completed day by day. Various energy harvesters and sensors have been inventedfor analyzing the factors involved in traffic movement like vehicle, road and environment. Among those,triboelectric nanogenerator (TENG) is considered to be advanced and next generation self-powered sensorsand energy harvester. Therefore, TENGs are widely studied and developed with various mechanismand structure. In this review article, we have studied the several mechanisms specific to the key elementsof traffic monitoring such as vehicle, road and environment. Since, without studying the shortcomings ofthe TENG, it is difficult to update the smart traffic monitoring system therefore along with the detailedstudy of several the design, structures and mechanism of TENG, challenges and limitations have also beenreviewed which will benefit the researchers working in this area and enhance the improvement in trafficmonitoring and safety.
