| Research Abstract |
Ciliary movement was mimed by PVDF film actuators. Lithographic process was used to fabricate interdigital electrodes which were made from aluminum thin films evapolated on both sides of the PVDF film. The fabricated PVDF actuator was actuated by applying a source voltage to the fabricated electrodes. Statical characterisities of the fabricated PVDF film actuator were investigated by atomic force microscopy using heterodyne interferometry. Scanning tunneling microscopy was used for atomic scale electrode formation.
A multiple probe force microscope was developed to observe displacements of the two position on surface simultaneously. In order to observe displacement distribution on PVDF film actuator, a new accurate microscopy using pulse laser diode was developed. Control methods using fuzzy control and Petri net were discussed to control distributed systems.
