Piezoresistive Sensitive Concrete

Piezoresistive Sensitive Concrete for Traffic Monitoring

This project aims the development of a sensitive conductive concrete, using nano carbon-based additions, able to sense strain stimuli, based on the piezoresistivity principle (electrical resistivity to deformation relationship). Although their several possible applications, this research is orientated to the development of concrete road sensors for traffic monitoring applications, able to sense axles passage, their velocity and weight.
