The electromechanical transduction characteristics of a water-swollen polyelectrolyte gel are examined under static loading conditions. This material offers great potential as a tactile sensor owing to its skin-like theological behaviour. The sensor operates by exploiting an equilibrium mechanoelectrical conversion mechanism that is exhibited by ionized gels. The distribution of electrochemical potential produced by the application of a compressive point load on the boundary of the gel is calculated using a continuum model and is shown to be a function of the local dilatation. Relevant material constants are determined experimentally; their effect on the response of the sensor is also discussed.
