Definitions
- the present invention relates to a structure of three-dimensional electrically conductive fabric, and in particular to a structure of three-dimensional electrically conductive fabric that features both resiliency and electrical conductivity.
- a conventional detection element 1 for physiological examination comprises a base layer 10 and an electrically conductive layer 11 formed on the base layer 10.
- the electrically conductive layer is attached to human skin surface to detect a signal generated by the human body.
- the electrically conductive layer 11 of such a detection element 1 is generally of poor resiliency and has poor electrical conductivity with human skin making it difficult to detect the signal generated by the human body and also making wear uncomfortable.
- a resilient layer 12 is arranged between the electrically conductive layer 11 and the base layer 10 so that contact tightness between the electrically conductive layer 11 and human skin can be improved with the resilient layer 12.
- a moisture-retaining material is also included in the layer to make the layer also function moisture retaining thereby improving electrical conductivity of the electrically conductive layer 11.
- the resilient layer 12 and the electrically conductive layer 11 are two separate layers, moisture must penetrate through the electrically conductive layer 11 before being absorbed by the resilient layer 12. Consequently, the absorbability of moisture is affected.
- the resilient layer 12 releases water between the electrically conductive layer 11 and human skin, the release of water is also affected by being blocked by the electrically conductive layer 11.
- the resilient layer 12 and the electrically conductive layer 11 are two separate layers that are bonded to each other by an external force (such as adhesion). These layers are easily detached from each other due to the high humidity long maintained by the resilient layer 12, making the detection element 1 losing its function.
- US 6 755 052 B1 discloses a knitted stretch spacer material with a face surface and a back surface in spaced apart relation with a body portion constructed therebetween. However, the material has no possibility to measure an electrical signal from a human body.
- WO 01/02052 A2 discloses a garment which can be used as an electrode. However, as there are only several elastic zones localized in the garment the resiliency is not very high.
- the present invention aims to provide a structure that possesses the characteristics of resiliency, electrical conduction, and moisture retention in order to achieve the goal of improving electrical conduction and lifespan of product.
- An object of the present invention is to provide a structure of three-dimensional electrically conductive fabric that is formed through being unitarily knitted and features resiliency and electrical conductivity.
- Another object of the present invention is to provide a structure of three-dimensional electrically conductive fabric that features moisture retention.
- the present invention provides a structure of three-dimensional electrically conductive fabric, according to claim 1.
- the first structural yarns and the second structural yarns are each one of polyester yarn, porous fiber yarn, alginate fiber yarn, carboxymethyl cellulose fiber yarn, and rayon fiber yarn.
- the electrically conductive yarns are one of metal fiber yarn, carbon nanotube fiber yarn, and carbon fiber yarn.
- the first elastic yarns and the second elastic yarns are each spandex yarn.
- the first support yarns and the second support yarns are each one of polyester yarn and nylon yarn.
- the first structural yarns, the first elastic yarns, and the electrically conductive yarns are arranged and interlaced through knitting to form the resilient conductive tissue.
- the second structural yarns and the second elastic yarns are arranged and interlaced through knitting to form the foundation tissue.
- the resilient conductive tissue, the foundation tissue, and the support tissue are unitarily combined to form the structure of three-dimensional electrically conductive fabric, in which the same planar tissue features both resiliency and electrical conductivity and also shows an effect of moisture retention through being combined with structural yarns that feature moisture retention.
- the structure of three-dimensional electrically conductive fabric according to the present invention comprises a resilient conductive tissue 20, a support tissue 30, and a foundation tissue 40, which are knitted unitarily to form the structure of three-dimensional electrically conductive fabric with the support tissue 30 arranged between and connecting the resilient conductive tissue 20 and the foundation tissue 40.
- FIG 4 is a perspective view showing, in an enlarged form, a portion of the structure of three-dimensional electrically conductive fabric in accordance with the present invention
- the resilient conductive tissue 20 is formed by arranging and interlacing, through proper fabric manufacturing process, a plurality of first structural yarns 200, a plurality of first elastic yarns 201, and a plurality of electrically conductive yarns 202 together.
- Each of the first structural yarns 200 is combined with each of the first elastic yarns 201 as a strand for being arranged alternately with each of the electrically conductive yarns 202.
- first structural yarns 200, the first elastic yarns 201, and the electrically conductive yarns 202 are alternately arranged through knitting to form the resilient conductive tissue 20.
- the foundation tissue 40 is formed by arranging and interlacing a plurality of second structural yarns 400 and second elastic yarns 401. Each of the second structural yarns 400 and each of the second elastic yarns 401 are arranged together as the same strand.
- the support tissue 30 is formed of a plurality of first support yarns 300 and a plurality of second support yarns 301 and connects between the resilient conductive tissue 20 and the foundation tissue 40, wherein each of the first support yarns 300 is arranged with each of the first structural yarns 200 and each of the first elastic yarns 201 and subsequently extends to the foundation tissue 40 to be arranged with each of the second structural yarns 400 and each of the second elastic yarns 401.
- Each of the second support yarns 301 is arranged with each of the electrically conductive yarns 202 and subsequently extends to the foundation tissue 40 to be arranged with each of the second structural yarns 400 and each of the second elastic yarns 401 in a manner of being spaced from the first support yarns.
- the interlaced arrangement of the first support yarns 300 and the second support yarns 301 provides improved resiliency to the structure of three-dimensional electrically conductive fabric of the present invention, so as to make a wearer comfortable when is used to make a wearable article. Further, the first support yarns 300 and the second support yarns 301 form tiny voids therebetween that help retaining moisture and improving electrical conductivity.
- the resilient conductive tissue 20 is formed by arranging and interlacing a plurality of first structural yarns 200, a plurality of first elastic yarns 201, and a plurality of electrically conductive yarns 202 together.
- Each of the first structural yarns 200 is combined with each of the first elastic yarns 201 as a strand for being arranged alternately with each of the electrically conductive yarns 202, whereby after the entirety of the structure of three-dimensional electrically conductive fabric is completely arranged when the stretching force of yarns are removed, the first elastic yarns 201 get contracting and squeeze the electrically conductive yarns 202 outward so that the electrically conductive yarns 202 project beyond the surface of the entire resilient conductive tissue 20. This ensures that when the fabric is placed on human body, the electrically conductive yarns 202 get contact with the human body first so that the structure of three-dimensional electrically conductive fabric according to the present invention may provide improved effect of detection.
- the first structural yarns 200 and the second structural yarns 400 can selectively be one of polyester yarn, porous fiber yarn, alginate fiber yarn, carboxymethyl cellulose fiber yarn, and rayon fiber yarn, among which porous fiber yarn, alginate fiber yarn, carboxymethyl cellulose fiber yarn, and rayon fiber yarn have the function of moisture retention. If the first structural yarns 200 and the second structural yarns 400 are selected from these four materials, then the structure of three-dimensional electrically conductive fabric according to the present invention may show the characteristics of resiliency, moisture retention, and electrical conductivity.
- the first elastic yarns 201 and the second elastic yarns 401 can be spandex yarn.
- the electrically conductive yarns 202 can selectively be one of metal fiber yarn, carbon nanotube fiber yarn, and carbon fiber yarn.
- the first support yarns 300 and the second support yarns 301 can selectively be one of polyester yarn and nylon yarn.
