The efforts given to optimize the linear strain response of polypyrrole (PPy) doped with alkyl benzene sulfonate (ABS) as these systems show particularly good chemical stability in aqueous systems and little toxicity are presented. The aims of the optimization is to obtain maximum length changes in a freely suspended polymer foil in response to a potential change and it includes attention to the composition of the polymer, to the synthesis conditions, and involves microstructuring of the polymer. As such, an analysis of the influence of the alkyl chain length on the properties of PPy doped with ABSs has shown that the obtainable strain decreases with increasing chain length for alkyl chains longer than C$-8$/.
