Measurement in the frequency range 3 mHz\u2013106 Hz of the dielectric characteristics of emeraldine base polyaniline dissolved in 1-methyl-2-pyrrolidinone and cast into bulk free-standing polymer films shows features similar to those reported by others and which are a result of microphase separation into reduced and oxidized repeat units. The gel-type water absorbent contains a tamarind seed polysaccharide including 90% or more dietary fiber, 1% or less protein and 1% or less ash; and a water-soluble organic substance including at least one or more of a polyhydric alcohol and water-soluble surfactant. The measured properties demonstrate work-function matching via contact doping. The encrypted request includes an interest vector of separately encrypted values identifying those elements of interest for the attribute. To guarantee energy supply even when switching to a short-circuit, the contact mechanics unit is coupled to a conversion unit, which converts a portion of the mechanical energy to be provided during switching-on into a second electric energy that supplies the trigger unit with electric energy during switching-on.
