1. Micro force sensor of the plate spring typeThe micro force sensor consists of a stainless steel plate spring (length 2 mm, width 1.5 mm, thickness 0.1 mm) on which a electric-resistance strain gauge is bonded. When the sensor is inserted into tendons and ligaments, a tension applied to their tissues causes the adjacent fibers to bend the plate spring. The bending strain is measured with the strain gauge. The in vivo tension in rat patellar tendon during treadmill running and jumping was measured using the sensor. As a result, the tension could be measured accurately.2. Micro force sensor of the needle typeA needle is composed of three stainless steel plates (width 1.0-1.5 mm, thickness 0.1-0.3 mm, length 15 mm). The needle has a cantilever in the top. A electric-resistance strain gauge or fiber optic strain gauge is bonded on the cantilever. A tension applied to tendons and ligaments causes the adjacent fibers of the tissues to bend the cantilever. The in vitro cyclic loading was applied to the rat patellar tendon into which the sensor was inserted. The required output was stably obtained from the sensor.

1.板弹簧式微力传感器该微力传感器由不锈钢板簧(长2 mm，宽1.5 mm，厚0.1 mm)组成，其上粘贴有电阻应变片。当传感器插入肌腱和韧带时，对其组织施加的张力会导致相邻的纤维弯曲钢板弹簧。弯曲应变是用应变计测量的。利用该传感器测量了大鼠在跑台跑步和跳跃过程中的体内张力。因此，可以准确地测量张力。针式微力传感器一根针由三块不锈钢板组成(宽度1.0-1.5 mm，厚度0.1-0.3 mm，长度15 mm)。这根针的顶部有一个悬臂。在悬臂上粘贴电阻应变片或光纤应变片。对肌腱和韧带施加的张力会导致邻近组织的纤维弯曲悬臂。将传感器植入的大鼠膝腱上施加体外循环载荷。传感器稳定地获得了所需的输出。
