In a more less near future, aeronautics could largely use light morphing structures which can advantageously replace the classical heavy actuation able to improve aircraft agility. This breaking technology can be easily initially evaluated without risk on drones. Existing laminar actuators using monolithic fibres and often bonded on surfaces, are small, use high driving voltages and are therefore rather brittle. The basic idea is to produce at low cost a sufficiently long, low voltage and robust enough fiber which can be easily handled to already produce actuator and which can be also in the future intimately mixed with passive fibres by conventional textile production means in order to realize with a better efficiency the deformation of larger surfaces. Robust sensors and energy harvesting devices can be also imagined. To succeed in such an ambitious challenge which has motivated the present research of development of Metal Core Piezoelectric Fibres (MCPF) and their numerical behaviour modelling, two processes have been investigated. For each a few obstacles have yet to be overcome.
