The specific embodiment
Below in conjunction with specific embodiment, further set forth this utility model.Should be understood that these embodiment only to be used for explanation this utility model and be not used in restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications this utility model after the content of having read this utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
As Fig. 1～shown in Figure 2, this utility model comprises induction region 1, join domain 2, external power supply 6, circuit board 7, described induction region 1 by veil coil 3, yarn coil 4 braiding form, described veil coil 3 is emerging in induction region 1 front, described ground yarn coil 4 is emerging in induction region 1 reverse side, described join domain 2 is positioned at induction region 1 outside, is woven on sensor carrier 8 by described ground yarn coil 4; The circuit board 7 that described veil coil 3 two ends connect external power supply 6 and are used for conversion of signals, storage, emission by lead-in wire 5 respectively.
Described veil coil 3 adopts the silver-plated conductive yam of chinlon to make, and the line density of the silver-plated conductive yam of described chinlon is 110dtex, and conductivity is 0.516 Ω/mm.
Described ground yarn coil 4 adopts the chinlon spandex core-spun yarn to make, and the heart yarn of described chinlon spandex core-spun yarn is spandex yarn, and the outsourcing yarn is polyamide staple fibre spun yarn, and the line density of heart yarn spandex thread is 22dtex, and the line density of the nylon stretch yarn of outsourcing is 33dtex.
Described induction region 1, join domain 2 all adopt the seamless underwear knitting machine to form through local plaiting method braiding.
