We report on the fabrication and characterization of spray-coated films with carbon nanotubes (CNT) as strain sensitive resistors. Spray coating is a flexible method for film deposition, which allows for cost-efficient processing of CNT dispersed in organic solvents. Specimens were realized on polymer substrates and change of electrical resistivity of the fabricated specimens was measured under tensile strain controlled by a testing machine.
