A strain amplification sensor having a first base portion being coupled to a first member to be strain measured, a second base portion being coupled to a second member to be strain measured, and an amplifying lever system pivotally coupled between the first base portion and the second base portion. The amplifying lever system includes attachment locations that induce opposing relative motion resulting in detectable deflection of the amplifying lever system in response to application of strain between the first base portion and the second base portion. L'invention se rapporte à un capteur d'amplification de contrainte ayant une première partie base accouplée à un premier élément à mesurer par extensométrie, une seconde partie base accouplée à un second élément à mesurer par extensométrie, et un système de levier d'amplification accouplé pivotant entre la première et la seconde partie base. Le système de levier d'amplification comprend des emplacements de fixation qui induisent un mouvement relatif opposé aboutissant à une déviation détectable dudit système en réponse à l'application d'une contrainte entre la première et la seconde partie base.
