Patent number: 11357104Abstract: The purpose of the present invention is to provide a garment-type electronic device capable of reducing discomfort during the wearing in the garment-type electronic device comprising an electrical wiring using stretchable conductor composition. In a part in contact with a body surface of a garment-type electronic device, a level difference at the boundary between the electrode portion where the conductor is exposed and the wiring portion covered with the insulating cover layer is substantially eliminated, whereby a garment type electronic device with a natural wearing feeling in which discomfort during wearing has been reduced is obtained. Furthermore, by providing the projections and the depressions in the fabric texture on its surface, a more natural wearing feeling is obtained. Such a garment-type electronic device can be produced by a printing transfer method.Type: GrantFiled: September 15, 2020Date of Patent: June 7, 2022Assignee: TOYOBO CO., LTD.Inventors: Euichul Kwon, Sonoko Ishimaru, Michihiko Irie, Maki Kinami

Patent number: 10959467Abstract: The present invention provides to a wearable smart device having electrical wiring comprising a stretchable conductive composition having excellent in durability such as repeated bending properties and repeated twisting properties, a material for realizing the wearable smart device, and a method for producing the wearable start device. An electrical wiring including a fine line having an electrical line interval of 1 mm or less, preferably the line width of less than 1 mm, is formed by printing a paste for forming a stretchable conductor containing metal-based conductive particles and a non-crosslinked elastomer, and further dried and cured at a low temperature condition of 120° C. for 30 minutes. As a result, the wearable smart device having electrical wiring constituted by fine lines without sagging of the edge is obtained.Type: GrantFiled: March 7, 2017Date of Patent: March 30, 2021Assignee: TOYOBO CO., LTD.Inventors: Yuko Nakao, Satoshi Imahashi, Michihiko Irie, Takashi Kondo, Maki Kinami

Patent number: 10546664Abstract: The purpose of the present invention is to provide a stretchable conductor that can be used to form a film having good repeated stretching durability, a garment-type election device that has a wire using the stretchable conductor, and a method for producing the same. Conductive particles, preferably silver particles, a predetermined quantity of a specific barium sulfate, and a flexible resin component are mixed together to obtain a stretchable conductor composition. A sheet made from the stretchable conductor composition thus obtained has a low initial conductivity, and a high conductivity retention rate when repeatedly stretched. By cutting the stretchable conductor composition into a predetermined shape and affixing the composition to fabric or the like that constitutes a garment, it is possible to achieve a garment-type device having electrical wiring with high stretchability.Type: GrantFiled: January 10, 2017Date of Patent: January 28, 2020Assignee: TOYOBO CO., LTD.Inventors: Hiromichi Yonekura, Satoshi Imahashi, Michihiko Irie, Takashi Kondo, Maki Kinami
