A System to Measure 3-Directional Relative Displacements for a Biomedical Application

A micro system for measuring the relative displacements between a bone and an implant in a prosthetic hip of a human being has been realized. Novel are the small dimensions of the system combined with the possibility to measure relative displacements in three directions. The system consists of a microsensor body, a mechanical transducer element made by precision mechanics, electronics, and the final package. The realization and test results of a prototype system are presented. Typical ranges for these prototypes are ±500 μm for lateral directions and ±50 μm in axial direction. © 1995 Springer-Verlag.
