The movement or travel of the actuator can also be adjusted and controlled in a stepless manner, and as it has no mechanical elements is completely noise free, removing mechanical vibrations that can be disturbing to the driver completely. This is of particular benefit within battery electric (BEV) and hybrid vehicles, where the baseline noise created by a standard internal combustion engine (ICE) is not present to mask any additional mechanical noises. The removal of the mechanical element also increases reliability through the elimination of traditional moving parts.
The energy consumption is also significantly lower when compared to a conventional coil system, because in a coil system you need permanent current or voltage to maintain a certain status, i.e. off or on. In the EAP system, the voltage is stored in the electrodes, and voltage is only required if a change in status from off to on or vice versa is necessary.Norbert Haberland
