The real-time monitoring of body physiologic information, has highly important application, such as electronic skin, wearable heart at medical treatment, health field
Defibrillator, the flexible circuit being placed in contact lens, wearable electrocardio respiration pickup etc..Flexible electronic and conditional electronic it
Between the most basic difference be design circuit substrate on, i.e. with flexible base board replace rigid substrates.Owing to textile has soft
Toughness and can the characteristic of random bending fold etc., when studying flexible wearable circuit, flexible fabric becomes first-selection substrate material
Material.Compliant conductive fabric disclosure satisfy that people's requirement for portability, flexibility and the comfortableness of wearable circuit.
Present stage, the construction method of flexible fabric surface conductance figure mainly has two categories below: 1, utilize textile weaving
Conductive yam is enrolled in the organizational structure of fabric by technique (knitting, woven, embroidery).2, printing technology (inkjet printing, silk screen are utilized
Printing) print conductive inks water or slurry on fabric, then carry out high temperature sintering.The weaving method such as knitting or woven can be by pre-
The conductive yam shuffling made inweaves in fabric structure, but is limited by the weave patterns (warp-wise or broadwise) of fabric, conductive yam
The direction enrolled can only be perpendicular or parallel to the selvedge of fabric, thus limits freely designing of conductive pattern on fabric.Thorn
Although embroidering and have good design freedom when conductive yam connects up, but it being higher to prefabricated conductive yam flexibility requirements, and
When preparation high accuracy circuit, with high costs.Inkjet printing or screen printing technique all compare dependence conductive ink or conductive paste
The development of material and sintering process.Common fabric is mostly porous material, meeting when fluid (ink or slurry) infiltrates on its surface
Produce " wicking " phenomenon, reduce the precision of gained conducting wire.So typically by increasing ink or slurry in actual production
Viscosity weaken this phenomenon, but excessive viscosity blocks jet orifice or silk screen hole sometimes.In addition, sintering process
The base material that the hot conditions used can make some high temperature degradable thermally decomposes, thus flexible electronic field is main now
The base material used is still resistant to elevated temperatures polyimides (PI) material.A lot of typographies contain fine metal particles by preparation
Conductive ink or slurry reduce the sintering temperature of prefabricated metal circuit diagram, to widen be suitable for Body regions.
The present invention is directed to existing Technology controllable precision be poor when fabric face builds conducting wire, process costs height,
The problems such as the applicable narrow range of base material, it is provided that a kind of operation that reduces, reduction cost, carry high efficiency flexible fabric surface conductance line
The construction method on road.Ultimate principle is first by fabric face chemical modification, improves the hydrophilic of fabric, and grafting simultaneously can be coordinated
The organo-functional group of adsorption activation metallic.Recycling pin type waxing technology forms hydrophobic region (wax pattern district) on fabric
With hydrophilic region (blank modified zone).Then being put into by fabric in activation colloid solution, hydrophilic region adsorption activation particle is formed
Catalysis active site, and grow in next step electroless plating reaction and the metal thin film patterns of wax pattern complementary.The present invention utilizes
Waxing technology, at fabric face Preformed circuits figure, forms the metallic circuit figure of complementation the most again.Owing to wax is directly with solid
The form of body transfers to fabric face from commercial paraffin paper, will not produce " wicking " phenomenon, the most prefabricated circuit diagram on fabric
