Paper Abstract
Environmental and electrical variables, as temperature, electrolyte concentration or driving current, influence
oxidation and reduction oxidation rates of free-standing polypyrrole/DBSA/ClO4- films. Under flow of a constant
current for a constant time, decreasing electrical energies are consumed to oxidize or to reduce the film under
increasing temperatures or rising electrolyte concentrations. By consuming the same charge under flow of rising
constant currents, the consumed electrical energy increases. As conclusion the consumed electrical energy by flow of
constant charges during oxidation, or reduction, of the film is a sensor of the electrochemical cell temperature, the
electrolyte concentration or the flowing current. Those sensing capabilities seem to be a general property of the
electrochemistry of conducting polymers. Any electrochemical based device, as actuators, polymeric batteries, smart
membranes, smart drug delivery devices and others, are expected to sense environmental conditions while working.
The sensing abilities of a complex actuator constituted by four polypyrrole films, two acting as electrodes (anodes or
cathodes) and the other two as counter electrodes (cathodes or anodes, respectively) are presented. Experimental
results are equivalent to sensing charge/discharge processes in all polymeric batteries.
