Abstract
A miniature actuating device with a carrier, a diaphragm, a hollow space formed between the carrier and the diaphragm and an insulating layer arranged between them and with two electrode terminals for producing an electrostatic field between the diaphragm and the carrier for an activated state. With an actuating device of this kind, it is desired that the throw can be achieved under the influence of the electrostatic field be rendered as large as possible. To that end, the hollow space is present only in the state of rest and in the activated state virtually disappears maintaining the diaphragm buckle free.
