“The first step towards a fully printed wireless temperature sensor has been successfully completed”
TECNALIA is developing a wireless temperature sensor embedded in a glass-fibre reinforced polymer based on Radio Frequency (RF) resonators.
Printed wireless sensors are an interesting research and development avenue for applications where integration of conventional sensors proves to be a challenge. Both the elimination of wires and the possibility of direct printing on various substrates considerably expand the range of applications. In particular, they have great potential in the field of multifunctional composites, as they allow the integration of sensors without damaging the material properties. These sensors are very useful for monitoring manufacturing processes and for advanced data management when manufacturing of large composite parts.
Fully printed wireless temperature sensor
In order to develop chipless wireless sensors, which can be fully integrated in composites, typical RF structures, such as Split Ring Resonators, are presented, as they are compatible with these chipless systems. TECNALIA has proven that these resonators, embedded in glass-fibre reinforced epoxy polymer, are sensitive to temperature. The first step towards a fully printed wireless temperature sensor has been successfully completed.
