Description
The "Smart Layer" project involves the development and integration of 2 main functions: underfloor heating of around 100W/m2, and wireless powering of appliances up to 100W.
Advantages for the housing market:
- Reduce the cost of electrification in new and renovation projects
- Reduce energy consumption
- Facilitating redevelopment
These 2 functions are integrated in a lé, located under the habitat covering structure. The potential markets are extremely vast:
- The private or public building,
- Urban furniture,
- Clothing: heated clothing, Vehicles: car, boat,
- Humanitarian crisis areas.
SPS acts as an integrator and end-user.
Objectifs
The aim of this project is to develop an integrated soil solution that will enable :
- Wirelessly power devices (up to 100W) and
- Enable communication between these devices
- Heating (about 100W/m2)

More details
The first work undertaken by Yncréa Méditerranée concerned the choice of the operating frequency and the EMC constraints. The figure below shows two graphs which allowed us to select the working frequency as well as the powers emitted in the neighbouring frequency ranges.
Based on these results, various prototypes were produced in collaboration with the project partners on its prototypes in crea Méditerranée carried out simulator modelling to predict behaviour and provide solutions.
The current modelling focuses on the losses in the transmission lines as well as the coupling that may occur between the remote feed antennas. The work that will take place in the remainder of phase 2 of the project will focus on the interaction that transmit antennas may have with the heating circuit but also on the optimization of the coupling between the transmit antenna and the secondary antennas. The figure below shows a modeling campaign on the coupling study between the antennas (top picture) and also on the power dissipation when all antennas are fed (bottom picture).
The project is innovative because it concerns a set of modular electrical strips intended to be associated with control components to form a system with several functions, in particular a heating function by Joule effect, a function of energy and data transmission by an electromagnetic channel.
There are solutions for heating coatings, solutions for electrically powering devices without contact and solutions for communication between devices. But there is no solution to realize these 3 tasks together.
