CLOTH-LIKE TRANSDUCER AND DEVICE INCLUDING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a cloth-like transducer having excellent flexibility and generating a stronger electric signal for an action in a specific direction, a device using the signal from the transducer, and/or a device that functions by inputting the electric signal.SOLUTION: The transducer includes piezoelectric units disposed roughly on the same plane so that conductive fibers B and piezoelectric fibers A are electrically connected. The piezoelectric fibers A mainly contain a polylactic acid and are quantified by a wide-angle X-ray diffraction analysis (WAXD). Homo PLA crystallinity X(%) and a crystal orientation degree A(%) satisfy Formula (1). X×A×A÷10≥0.26...(1).SELECTED DRAWING: Figure 1
