Patent number: 11751768Abstract: A biological data measurement device has patches. A patch to be mounted on the human body basically includes first and second heat insulators, first and second temperature measurement circuits, and a belt-shaped wiring film (bus wire). Therefore, the configuration is simple. For example, a thickness can be approximately several mm, and a weight can be approximately several grams. The patch is easily mounted on the human body, and is inexpensive. The patch is equipped with a selection circuit, and selectively outputs a temperature signal of a first thermometer and a temperature signal of a second thermometer at a predetermined timing. Accordingly, even in a case where the patches are mounted on a plurality of locations of the human body, the number of wires is settled by the number required for one patch. The number of wires can be significantly reduced, compared to the number of wires in the related art.Type: GrantFiled: October 31, 2018Date of Patent: September 12, 2023Assignee: TECHNO-COMMONS, INC.Inventor: Akio Tanaka
