11Summary/Conclusions
Thermal energy harvesting by thermoelectric materials
The interest on thermoelectric materials for harvesting waste heat in industry is continuously
increasing due to their simplicity, compactness and reliability.
However, the poor efficiency of TEGs limits their use to small-medium sized applications.
Still, they may play an important role in the road to Industry 4.0, where monitoring and wireless
sensoring could boost the use of TE materials
The research in new materials is crutial to improve the TE efficiency with non-toxic and cheaper
raw materials.
