    • An apparatus for load and displacement sensing adapted for measuring normal and shear forces exerted on load bearing portions of a body. The apparatus includes a deformable pad and a plurality of sensors. Each sensor includes at least one magnet and at least one Hall-effect transducer affixed to opposite sides of the deformable pad. Normal forces are measured utilizing magnets having a planar North and South polarizations and the magnitude and direction of shear forces are measured utilizing magnets having alternating North and South pole segments disposed longitudinally therewithin. In another embodiment, normal and shear forces are measured utilizing a magnet having a point-magnetization. The force exerted on the body deforms the pad, bringing the magnet in close proximity to the transducer, which senses the change in the magnetic flux density.
    • 一种用于测量施加在身体的承载部分上的正常和剪切力的负载和位移感测装置。 该装置包括可变形垫和多个传感器。 每个传感器包括至少一个磁体和至少一个固定在可变形焊盘的相对侧上的霍尔效应传感器。 使用具有平面的北极和南极偏振的磁体来测量法向力,并且利用具有在其中纵向设置的交替的北极和南极段的磁体来测量剪切力的大小和方向。 在另一个实施例中,利用具有点磁化的磁体来测量法向力和剪切力。 施加在身体上的力使焊盘变形,使磁体靠近传感器,其感测磁通密度的变化。
