GRAPSS – Graphene-Polymeric Spray Sensor for Shape Recognition of Super-Deformable Structures

Obiettivo

The GRAPSS – Graphene-Polymeric Spray Sensor for Shape Recognition of Super-Deformable Structures – Project, funded by CIRA within the "Curiosity Driven" internal action, aims at designing, realizing and experimentally characterize a sprayable sensor, based on the graphene technology, for the measurement of large deformations, with shape reconstruction and structural health monitoring purposes.

Within the two years of duration, the Project foresees: the production of the specifications of the sensor, on the basis of the requirements coming from the aerospace industry; the development of a modeling tool, to predict the relation between the electrical resistance and the strain; the identification of the materials and processes used for the fabrication of the sensor, including the graphene dispersion within the polymeric matrix and the deposition through the aerograph; the experimental validation, including mechanical characterization (verification of the ability of the sensor in withstanding the deformations), metrological characterizations (repeatability of the processes and of the measurements), environmental characterizations, to estimate the behavior and the performance of the sensor in typical aerospace operational conditions.

Two versions of the sensor have been planned: a first issue aimed at demonstrating the possibility of measuring high deformations on metallic structural elements; a second issue, integrated onto anisotropic and non conventional materials (shape memory / super-elastic alloys, shape memory polymers) will allow the validation of the concept not only in presence of large deformations, but also to achieve measures at local and global level, through a dedicated, optimized layout of the sensor.
