摘要

The piezoelectric constant of a poly(L-lactic acid) (PLLA) fiber is larger than that of other piezoelectric polymers. It is well known that it is easier to fabricate large devices with a flexible shape using polymer materials than using inorganic materials. Thus, on the basis of the features of polymer materials, we attempted to fabricate a PLLA actuator for a large macroscale physical object using PLLA fibers. We consider how to bundle PLLA fibers into a tubular-type polymeric actuator (PLLAFTTPA) with electrodes for producing piezoelectric motion under the application of voltage. Then, by thermal welding, a PLLAFTTPA with electrodes on its inner and outer surfaces was manufactured. Finally, we succeeded in producing a PLLAFTTPA with a diameter of 1 cm and a length of 12 cm. We observed that, under the application of an ac voltage of 2kV, the PLLAFTTPA could be tilted 20 μm in the fixed direction when the base of the PLLAFTTPA was mounted.
