Low cost pressure sensors for impact detection in composite structures

A new technology of flexible pressure sensors is developed using conducting polymers as electroactive materials on plastic substrates. The sensor measures quantitative pressure and the use of an appropriate synthesis strategy in the electroactive material tuning an adequate electrical conductivity and film morphology allows working pressure ranges to be taylor-made designed. Using low cost materials, high surface sensors are easily fabricated. The present work describes the integration of this innovative, low cost and flexible technology on composite structures opening interesting potential opportunities for impact detection and measurements on these types of components.
