Abstract
The invention is a mechanical sensor produced from a polymer film whose upper part (A) is made conductive, the lower part (B) remaining an insulator. When a strain is applied, the mechanical sensor according to the invention distorts, varying the resistance of part (A) and thus allowing the strain to be measured. Preferably, the polymer used is a thermostable polymer.
