Abstract
The invention relates to a pneumatic actuator composed of cuts of a gas-tight film which are interconnected so as to form hollow film elements that are gas-tight towards the outside. The hollow film elements are interconnected by means of air ducts while forming a fan-shaped structure from a cross-sectional perspective. The actuator, which is fastened to a component, is swiveled about a common edge of the hollow film elements when compressed gas is delivered via a connection. The swiveling movement of the actuator can be used for gripping and holding objects or transmitting optical signals.
