Abstract
A stretchable conductor of the present invention includes: a mixture which is configured of a stretchable portion made of an elastomer, and at least one type of conductive particles dispersed in the stretchable portion; and a conducting portion in which the conductive particles are aggregated in a higher concentration at one or a plurality of positions on an interface of the mixture than that at positions located in an inner portion of the mixture.
Claims5
A stretchable conductor, comprising:
- a stretchable portion;
- and
- a conducting portion;
- wherein:
- the stretchable portion is made of an elastomer, a plurality of conductive particles being dispersed within the elastomer;
- the conducting portion is made of an elastomer, a plurality of conductive particles being dispersed within the elastomer in a higher concentration than that of the stretchable portion;
- the conducting portion is formed at one or a plurality of positions on an interface of the elastomer;
- the plurality of conductive particles are arranged so as to overlap each other, and dispersed within the elastomer in the conducting portion;
- and
- the conducting portion maintains the conductivity greater than 100 siemens when an extension of 50% to 200% of strain is applied.
