Development of application oriented novel materials and structures. Organic, inorganic and hybrid structures are processed and characterized and their application potential established. Most of the material development is oriented to sensor and actuators applications. Other areas such as energy generation and storage are also considered due to the potential of some of the developed materials in these areas.

Polymer-based magnetoelectric (ME) materials are an interesting, challenging and innovative research field, that will bridge the gap between fundamental research and applications in the near future.
The values of the magnetoelectric coefficients found on materials such as PVDF/CoFe2O4 films (Figure 1a) and PVDF/CoFe2O4 nanofibers (Figure 1b) as well as the broad range of the magnetic field at which they respond, together with the flexibility, robustness and ease of fabrication related to the polymer-based materials, allow a large range of applications, in particular in the fields of sensors and actuators.
