Starting point for innovation

Sensors at the temperature limit

The purpose of the SAWHOT project (Surface Acoustic Wave wireless sensors for High Operating Temperature environments) is to improve the performance of wireless SAW sensors at extreme temperatures.

New solutions

The SAWHOT consortium develops high-temperature wireless solutions based on SAW technology for use in jet engines with the aim of reducing the amount of wiring currently needed and enabling new measurement techniques.

Incomparable performance under adverse conditions

SAW technologies have been used in sensors for over 20 years because of their exceptional long-term stability. More recent wireless systems have led to significant improvements in the sensors. Making the wireless technology even more powerful and enabling use under the most extreme temperature conditions is the next logical step forward. Concrete goals include:

  • Characterisation and selection of crystal cuts for high temperatures (up to 900°C)
  • Development of a complete high-temperature system 
  • Expansion of the opportunities for process control in extreme industrial environments

Partnerships for the best results

When the project is completed, it will be possible to sense physical parameters under extreme temperature conditions between -20°C and +650°C and monitor production processes. To ensure the sensors will be suitable for commercial use, the international project team includes several industrial consumers. An interesting fact is that the project is based on bilateral cooperation between the EU and Russia, which has resulted in a unique team.

Funding and procedure

SAWHOT is co-funded by the European Commission under the Seventh Framework Programme for Research and Technological Development (FP7).
