A Novel Weigh-In Motion Sensor Using An Asphalt-Embedded Thin Film of Graphene-On-Clay and Carbon-Nanotubes
Résumé
This study deals with the development of an innovative weigh-in-motion (WIM) sensor. An electrically conductive nanocomposite material based on a mixture of graphene supported on sepiolite and carbon nanotubes was developed. Deposited on bituminous mix with copper electrodes, it is used as a force sensor. We detail the sensor fabrication process and study its sensitivity to a compressive force.
