Outside, also there are thermojunction type, condenser type, diode/triode, thin film electrochemistry temperature sensor of some flexible bases etc..But,
There is very big problem in sensitivity, temperature-responsive time, the stability of environment and multimetering in them.
Temperature sensor based on fabric has the advantages that ventilative, soft, stretchable and washable, therefore be readily applicable to can
The portable temperature monitoring equipment of wearing.At this stage, mainly using existing temperature sensor, embed it in realization in fabric and knit
Thing sensor, its preparation method has：Be sewn in fabric substrate, be coated on by complicated fabric tissue in fabric or
Person in the form of yarn to be woven into fabric.Such as patent CN 104264315A disclose the method that temperature sensor is embedded in fabric,
Its specific method for weaving using two-layer fabric, dual layer section is coated on using two-layer fabric by temperature sensor, and it can be by
Temperature sensor is preferably woven into fabric, and the weft yarn of two-layer fabric is High Shrinkage Long Polyester Fibre, after heat treatment can be with
It is coated on securely in fabric.But the method for this cladding makes temperature sensor be not readily accessible to skin, to measurement of bldy temperature knot
The precision of fruit produces influence, in addition, the quality of existing temperature sensor is hard etc., feature can not change.Therefore, develop ventilative, soft
Property, large deformation, wash resistant, endurance, sensitivity are high and to can accurately measure the fabric base temperature sensor of body temperature very meaningful.
