A mitt consists of a hollow flexible body having an interior, an exterior, a sleeve portion and a grip portion positioned at a remote end of the sleeve portion. By combining the multiplied input voltages, a linear interpolation is provided based upon the factor r. The preparation of the cross linked polymer involves selection of vinyl monomers bearing functional groups that bind to cobalt, formation of a complex of these monomers with cobalt and subsequent polymerization of the complex in presence of a crosslinker.
