摘要： A thread that includes a first fiber having at least one groove extending in a length direction thereof; and at least one second fiber constructed to generate a potential by external energy. The second fiber is disposed in a region corresponding to the groove of the first fiber such that a space is between the groove of the first fiber and the second fiber.

摘要： A touch input device that includes a touch sensor and a control unit. The touch sensor includes a base material, a piezoelectric film, a plurality of first detecting conductors and a plurality of second detecting conductors. The base material is a flat plate. The piezoelectric film is made of uniaxially stretched PLLA, and is arranged on one principal surface of the base material. The first detecting conductors are arranged on a surface of the piezoelectric film opposite to the base material. The plurality of second detecting conductors are arranged on a surface opposite to the surface of the base material which abuts on the piezoelectric film. The control unit detects an operation position and a press by using detection signals outputted from the first detecting conductors and the second detecting conductors.
