Electronic systems are present in our everyday lives. In many applications, they have complemented or replaced functions performed by other systems based on mechanic, electromechanic, hydraulic, and pneumatic principles, as is the case for modern electronic aircraft.¹  This has enhanced innovation and competitiveness in all sectors of the economy, having a positive impact on our lives. Another factor responsible for the success of electronic systems relies on the fact that the interaction between electronic systems and humans has been enriched by the integration of a generation of smart low-cost sensors. Apart from smart mobile phones, this integration has made wearable devices possible, which will give rise to a new commercial family of products.
