Title: ELECTROACTIVE POLYMER TRANSDUCER AND SWITCHING DEVICE WITH AN ELECTROACTIVE POLYMER TRANSDUCER
Abstract:
The invention is about an electroactive polymer transducer (10), comprising a first stack configuration (11) and a second stack configuration (12), each stack configuration (11, 12) having a multitude of electroactive polymer layers (13), layered on top of each other, with electrodes (14) disposed between adjacent layers of electroactive polymer, whereby the electrodes of each stack configuration are alternately interconnected to form an electrode arrangement with two interlaced electrode configurations (15, 16; 15', 16'), wherein each stack configuration has a fixed (17, 17') end and a movable end (18, 18'), wherein a first fixed end (17) is the fixed end of the first stack configuration (11) and a second fixed end (17') is the fixed end of the second stack configuration (12), and wherein the first and the second fixed ends (17, 17') are fixed relatively to each other, wherein a first movable end (18) is the movable end of the first stack configuration (11) and a second movable end (18') is the movable end of the second stack transducer (12), and wherein the first and second movable ends (18, 18') are coupled together to form a coupling zone (19) for coupling to an external load.
