| Outline of Final Research Achievements |
We designed a piezoelectric polymer film actuator using poly(L-lactide) (PLLA) and poly(D-lactide) (PDLA) films. On the basis of their piezoelectric characteristics, we were able to realize a PDLA and PLLA multilayer film (PDLA/PLLA multilayer) with a simple structure. The PDLA/PLLA multilayer film of centimeter-order size shows a large piezoelectric resonance, and its piezoelectric performance is equivalent to that of a practical piezoelectric ceramic. First, we introduce the piezoelectric characteristics of a PLLA film and the concept of actuation system using PLLA film. Next, the fabrication process of PDLA/PLLA multilayer film and its piezoelectric characteristics were summarized. Finally, the typical examples of developed piezoelectric polymer actuation system using PDLA/PLLA multilayer film were described specifically in order to clarify the possibility of new application of piezoelectric polymer actuation system.
