Abstract: A specific region of a polylactic acid sheet is heated by a microwave. To allow the polylactic acid sheet to exhibit piezoelectricity in the thickness direction of the polylactic acid sheet, a high voltage is applied to the heated polylactic acid sheet in the thickness direction of the polylactic acid sheet, and thereby the screw axes of at least a part of the polylactic acid molecules are relatively aligned with the thickness direction. Then the polylactic acid sheet is rapidly cooled, and thereby the polylactic acid molecules are immobilized. The same step is executed for other regions of the polylactic acid sheet, and thereby piezoelectricity is imparted to a wide area of the polylactic acid sheet in the thickness direction. The resultant piezoelectric sheet is capable of exhibiting a high piezoelectricity in the thickness direction.

Abstract: An imprint method using a mold includes the steps of applying on a substrate a resin composed of a mixture of an ultraviolet curable resin cured with ultraviolet light and a luminescent material that undergoes fluorescence or phosphorescence upon receiving ultraviolet light, imprinting the mold into the resin applied to the substrate, curing the resin applied to the substrate using ultraviolet light, releasing the mold from the substrate imprinted with the pattern, and detecting light from any residual resin remaining on the mold. The imprint method can use an imprint apparatus that includes a light-emission detecting unit configured to detect light emitted from the luminescent material. After the mold is released from the resin on the substrate, the detecting step can use the light-emission detecting unit to detect light emitted from any residual resin remaining in a concave and convex portion of the pattern formed on the mold.
