Université d'Evry: Haptic actuators based on conducting polymer

The Universities of Cergy and Evry are jointly investigating on how electronically conducting polymer (ECP) may be used for new tactile display interfaces. The basic idea is to combine a polymer electrolyte and non conducting polymers into an interpenetrating polymer network (IPN) architecture as a host matrix. This technology appears to be very promising because of its lightness, resistance, flexibility and low energy consumption.

The main features to be enhanced are the actual output forces (beyond 0.1N) and the bandwidth (30 to 50Hz) of the elementary taxel (or tactor) conveying the sensory stimuli. If successful, this investigation would lead to the first entirely solid all polymer made actuator which could be used as an alternative to existing cumbersome technologies.
