Piezoelectric macro-fiber composite actuator and manufacturing method

摘要

An apparatus comprising:
a piezo-electric material structure having a first side and a second side, the piezoelectric material structure comprising a plurality of fibers (26) in juxtaposition, each fiber further having a first side and a second side, the first and second sides of the fibers defining the first and second sides, respectively, of the piezo-electric material structure;
a first film (28) bonded to the first side of the structure, the first film having a first side and a second side, the first film further comprising first and second conductive patterns (30,32), each conductive pattern being in electrical contact with the piezo-electric material structure, the first conductive pattern being electrically isolated from the second conductive pattern, the first and second conductive patterns each having a plurality of electrodes which form a pattern of interdigitated electrodes; and
a second film (42) bonded to the second side of the structure. The second film may have first and second conductive patterns (44,46) similar to the first film.
