• 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 2 kV, the PLLAFTTPA could be tilted 20 μm in the fixed direction when the base of the PLLAFTTPA was mounted.
