14. 2). However, because the present focus is on the fundamental material performance rather than electronic performance, we make the simplest physical assumption that p is constant.
15. The silicone films are based on a polydimethyl siloxane backbone. They were diluted in naphtha solvent, spin-coated, cured, and released. The HS3 silicone was centrifugea to remove pigment particles before spin coating. VHB 4910 is available in film form with a removable liner backing. The acrylic elastomer is made of mixtures of aliphatic acrylate photocured during film processing. Its elasticity results from the combination of the soft, branched aliphatic groups and the light cross-linking of the acrylic polymer chains. The zero-strain thicknesses of the materials were typically 225 μm for HS3, 50 μm for CF19-2186, and 1000 um for the VHB 4910 acrylic. The relative dielectric constant at 1 kHz is 2.8 for the two silicones and was measured at 4.8 ± 0.5 for the VHB 4910 acrylic.
