Abstract
An apparatus for manipulating an object includes a substrate, an electrically conductive layer disposed on the substrate, and a porous medium comprising an electrically conductive material. The apparatus also includes a dielectric layer conformally disposed on the porous medium to insulate the porous medium from the object during use. The porosity of the porous medium is about 90% or greater. The adhesive strength of the porous medium is about 1 kPa or lower, and the modulus of the porous medium is about 1 GPa or lower.
