A French research team has developed a non-destructive method to measure the humidity level in bulk materials.
This research team is represented by a technology transfer department established more than 8 years ago.
This department is responsible for protecting and leveraging the intellectual property generated by a major R&D institution in the Paris region.
In the construction industry, it is essential to control the residual humidity level of the underlying materials (for concrete or mortar) to ensure that the duration of the drying phase (a few days to a few weeks) is sufficient. Consequently the building industry increases substantially the construction time to leave a safety margin for the drying process, which causes significant increase in costs.
The present technology is a method for the non-destructive measurement of the humidity level of a material and is based in four steps. First, a radiofrequency signal is emitted to an antenna embedded in the material. A reflected signal is subsequently received from the antenna and analyzed to determine its resonant frequencies. Finally, the degree of humidity of the material is estimated based upon the determined resonant frequencies. The system includes a measurement device such as a reflectometer, a very low cost antenna embedded in the material and an interface between the antenna and the measurement device. This method allows a precise analysis of the level of humidity and the progress of drying of a material.
Other industrial sectors such as biomass (fuelwood) and agriculture, that require the humidity control of large volumes of materials (wooden fuel chips, grain silos…) could benefit from this new and cost-effective technology.
The partner could be a company interested in :
- a license agreement as the R&D institution is ready to negociate directly the patents rights for specific applications, or
- a technical cooperation agreement.
