A traction force sensor comprises at least one strain gauge (3) in a tension piece (1) comprising a central rectilinear segment (11) and two folds (10) at an angle, significantly thicker than the central rectilinear segment. The strain gauge (3) is arranged in said central rectilinear segment in such a manner that a traction force on the fastening ends (12) of the tension piece (1) results in a U-shaped buckling (4) of the central rectilinear segment. The invention also comprises a processing module (5) connected to the strain gauge (3), adapted to detect and process as data the elastic deformations caused in the central rectilinear segment by the longitudinal stresses generated by traction on the fastening ends (12) of the tension piece. The invention allows a portable and low cost wireless sensor to be produced. 拉力传感器包括张紧器(1)中的至少一个应变仪(3)，所述张紧器包括直中心区段(11)和两个倾斜的弯曲部(10)，所述两个倾斜的弯曲部的厚度明显比直中心区段的厚度大。所述应变仪(3)布置在所述直中心区段中，以这种方式，张紧器(1)的附接末端(12)上的拉力引起直中心区段的U形形变(4)。本发明还包括连接到所述应变仪(3)的处理模块(5)，适于检测和处理在直中心区段中的弹性形变的数据，所述弹性形变
