A modulus-gradient conductive core–shell structure in an elastomer is fabricated by magnetic alignment and printing process for stretchable via application. Shell structures with rigid silicone resin prevent the nickel conductive core from mechanical deformation. Electrical conductivity is maintained under large uniaxial strain up to 80%. In addition, monolithic structure enables us to consider a facile fabrication strategy of the multilayered stretchable system.
