AB  - We introduce a method for sealing liquid metal (LM) circuits with soft 
      anisotropic conductors that prevent leaking, while simultaneously allowing for 
      electrical contact with skin and surface mounted electronics. These films are 
      composed of polydimethylsiloxane (PDMS) embedded with vertically aligned columns 
      of ferromagnetic Ag-Ni microparticles. The microparticles are magnetically 
      aligned and support electrical conductivity only through the thickness (z-axis) 
      of the elastomer film. Measurements on 10-40% (by wt) composites show moderate 
      volumetric resistivity (as low as rho = 0.03 Omega/m) through the thickness and no 
      conductivity between adjacent traces. Functionality is demonstrated with several 
      illustrative applications related to tactile sensing and electronics hardware 
      integration.
