Development of an adaptive control architecture and test-bench validation for a knee joint of a transfemoral prosthesis
Motivation of the study. Transfemoral lower-limb amputations significantly impact mobility and quality of life, motivating continuous research and development in the field of active prosthetic devices. In recent years, powered transfemoral prostheses have emerged as a promising solution to restore more natural and efficient gait patterns by actively assisting the user during locomotion. A key

Mechanical nonlinearities (Geometric or Contact) in inertial MEMS sensors
Mechanical nonlinearities play an important role in inertial MEMS sensors and cannot be avoided. The trend to push the performance to the limits caused second-order nonlinear effects to become a critical phenomenon that must be considered: these effects are already visible and characterized on mass production devices. External shocks and vibrations could also induce other

Out-of-plane stroboscopic analysis of MEMS motion sensors
Goal: implement a system for optical stroboscopic analysis of TDK’s MEMS accelerometers and gyroscopes, aimed at the characterization of out-of-plane resonant modes in those devices Strategy: enhance TDK’s existing system for in-plane stroboscopic optical analysis, based on the usage of infrared microscope and synchronously controlled light source, to add the out-of-plane capability.
