    摘要: A fabric material with an electrode wiring includes: a fabric material body with stretchability; a first electrode portion that is disposed on a surface or in the interior of the fabric material body, and that includes a conductive linear body; a first wiring portion that is disposed on the surface or in the interior of the fabric material body so as to be electrically connected to the first electrode portion, and that includes a conductive linear body; a second electrode portion that is disposed on the surface or in the interior of the fabric material body, and that includes a conductive linear body; and a second wiring portion that is disposed on the surface or in the interior of the fabric material body so as to be electrically connected to the second electrode portion, and that includes a conductive linear body. In the fabric material with an electrode wiring, a resistance value between the first electrode portion and the second electrode portion is varied by stretching the fabric material with an electrode wiring.

    摘要: The acoustic fiber transducer has a piezoelectric domain with Young's modulus, Epiezo, and including a non-centrosymmetric crystalline-phase piezoelectric material and inorganic piezoelectric particles. At least one charge collector domain is in electrical connection with the piezoelectric domain and includes an electrically conductive material operative to collect electrical charge generated in the piezoelectric domain. At least one electrical conductor is in electrical contact with the at least one charge collector domain and includes an electrically conductive material operative to transport electrical charge from a charge collector domain to an end of the acoustic fiber transducer as an electrical signal indicative of input acoustic sound pressure on a matrix of textile fibers that includes the acoustic fiber transducer. Outer acoustic energy transmission material has a Young's modulus Etrans, of 0.3 Pa-500 MPa, for matching vibrational modes of the textile fiber matrix. A ratio of Epiezo/Etrans is between about 5 and about 70,000.
