A strain sensor consisting of a non conducting polymer incorporating conductive nanoparticles below the percolation threshold and preferably less than 10 % v/v of the polymer. The polymer is a polyimide and the conducting nanoparticle is carbon black having an average particle size of 30-40 nm and an aggregate size of 100-200 nm. The sensor can sense strain in extension, compression and torsion.
