Patent number: 11641899Abstract: A garment for measuring biological information equipped with an electrode and wiring, with which noise can be prevented from being mixed in to the biological electric signals to be read, and with which a wearer feels less discomfort, even under dry condition while the garment is worn. Static electrical charge generated while the garment is worn is suppressed to decrease the noise in the biological electric signals to be read by selecting a combination of electrically insulating materials constituting the garment that have smaller gap of frictional electrostatic voltage, as well as using the electrode and wiring that are stretchy and have high conductivity even when being stretched to reduce discomfort while the garment is worn.Type: GrantFiled: May 24, 2018Date of Patent: May 9, 2023Assignee: TOYOBO CO., LTD.Inventor: Haruhiko Narusawa

Publication number: 20200221965Abstract: A living-body contact electrode used primarily in a garment for measuring living-body information, which is comfortable to wear, even during exercise, without rubbing between the electrode and the skin while acquiring a stable electrical signal in a dry state and a wet state. A living-body contact electrode can acquire a living-body electrical signal with decreased electrical noises by suppressing the displacement of the electrode without impairing feeling and feel of wearing by suppressing the skin irritation. This is achieved by limiting the coefficient of static friction of the surface of the electrode with respect to the skin, by decreasing the frictional coefficient of an electrical wiring part to be equal to or less than a predetermined value, and by combining the electrical wiring part with the electrode.Type: ApplicationFiled: August 23, 2018Publication date: July 16, 2020Applicant: TOYOBO CO., LTD.Inventor: Haruhiko NARUSAWA
