Abstract
A method actuates a pumping device that has an optimal driving voltage. The pumping device includes a pumping chamber that has a pumping membrane, an inlet and an outlet chamber, a voltage controlled actuator connected to the pumping membrane, a stop position defined by a mechanical stop, and a sensor for determining whether the pumping membrane has reached the mechanical stop. The method performs a learning and working phase. The learning phase is adapted to determine the optimal driving voltage.
