What is it about?
Graphene as a material used in engineering applications has been on the rise in the last decade due to being a material with interesting electrical and structural properties. This possibility offers a very wide range of technological applications. Among the potential fields of application is in the development of new sensors for structural applications. Recently the combination of graphene with cross-linked polysilicones has been proposed. This compound has interesting electrical and visco-elastic properties that have allowed the development of highly sensitive pressure and strain sensors. For this reason, their use as strain sensors in structures through structural health monitoring systems opens up an interesting field of research.

Why is it important?
In this work the key aspects of the manufacture of a crosslinked polysilicone- graphene strain sensor are reviewed, in this way, we can visualize the route to follow and the state of the process in which we are.
Perspectives
The cross-linked polysilicone samples of our manufacturer were compared with the commercial silly putty through a compression test, being able to observe that PSR1 shows a behavior similar to the reference one, which is an indicator of which one will be used for manufacturing the sensor.
