传感器被开发用于测量在三个正交方向上施加在假肢窝内的膝下截肢者残肢行走期间的应力。三个正交方向均采用应变片测量技术。四个换能器的仪表误差平均小于4.2%的满量程输出（FSO）的法向和小于0.9%的FSO的剪切方向。在步行试验中收集的截肢者的测量结果。>
Transducers were developed to measure stresses in three orthogonal directions applied on a below-knee amputee residual limb within a prosthetic socket during walking. Strain-gage measurement techniques were used for all three orthogonal directions. Instrumentation error for four transducers averaged less than 4.2% full-scale output (FSO) for the normal direction and less than 0.9% FSO for shear directions. Measurements from amputee subjects collected during walking trials are presented. >
