Ecole Polytechnique and IFSTTAR have developed a printing technology to fabricate piezoresistive flexible sensors out of a random assembly of carbon nanotubes (CNT) deposited on polymers. The films are stretchable by applying strain along different axes and recover their initial configurations upon releasing the strain. They can therefore be considered, as a rough approximation, as spring-like structures made of carbon nanotubes.

Their overall electric conductivity is sensitive to strain, but also depends of the conduction mechanisms in the CNT’s, the contact between the CNT’s and the environment, etc. We seek to understand the multiscale physical phenomena responsible for the conductivity and piezoresistivity of the sensors using coupled multiphysics experiments.
