Bionix Multistation Wear Simulators
Aiding researchers in developing better joint implant designs through long term wear testing, component optimization and material properties characterization. These systems also provide a realistic and practical compromise between general-wear screening devices (such as pin-on-disk systems) and the intensive research accomplished through full-scale simulation and modeling.
