| Abstract Scope |
The European Green Deal provides guidelines towards research and innovation to drive the necessary change to ensure ecological and economic transition. Ceramics industry strongly contributes to energy consumption due to high temperature sintering processes. Implementing alternative technologies and strategies is a necessity and a challenge that involves several material-related issues. In the field of piezoelectric materials, the interest of lead-free ceramics no longer needs to be justified, and the focus is on optimizing performances in an environmentally-friendly fabrication process. Our investigations target the optimization of sintering and screen-printing processes of (KNa)NbO3 based ceramics and thick films to design flexible devices for energy harvesting applications. Chemistry and grain size are key parameters to control piezoelectric performances. Scientific and technological levers and locks can be highlighted and will be described. The assessment of the various criteria contributing to the environmental impact of our research, through Life Cycle Assessment will be discussed. |
