The presented results suggest that statistically controlled Graphene reinforced functional prototypes can be usefully employed as sensors for bio-medical and engineering applications.
But hitherto only few studies have been reported for development of Graphene reinforced acrylonitrile butadiene styrene (ABS) thermoplastic for potential application in manufacturing of biomedical and engineering sensing elements by 3D printing.
Hence the functional prototypes so prepared can be used as thermal sensors for various engineering applications.
Particular interesting is also the use of graphene-based sensing elements in civil engineering structures [15]-[25], laminated members [26]-[30], mechanical metamaterials [31]-[33], and biological systems [34]-[36], in order to create embedded surface sensors aimed at controlling the durability and the structural health monitoring.

Understanding the mechanical behavior of cemented soils is of major importance for geotechnical engineering, since the properties of this material directly affects the performance of current engineering projects.
