In recent decades, increasing attention has been directed towards improving comfort and driving stability. In this context, the demand for suspension systems capable of effectively adapting to the excitations coming from the road irregularities became evident. This led to the development of semi-active and active suspensions, now available even in non-premium vehicles. In addition, the need to reduce CO2 emissions, and thus become sustainable for the planet, has led the automotive industry to considerable changes. In recent years, there has been a further push in the electrification direction. This is evidenced by the development of systems, which enhance the efficiency of the electric vehicle through energy harvesting.
