During micro-assembly processes, surface forces influence the behavior of micro-objects more than volumic forces. Generally contacts happen between a microgripper and a micro-objet or a substrate and a micro-object. The pull-off force which represents the force required to break a contact is one of the predominant problem in micro-assembly. Now, current force measurements are mostly focused on ...

The analysis of nanomechanical properties is becoming an increasingly useful tool in a large variety of fields, ranging from biology to polymer science. The Atomic Force Microscope, AFM, can bridge the information about morphology, obtained with outstanding resolution, to local mechanical properties. When performing an AFM nanoindentation, the rough force curve, i.e. the plot of voltage output ...

Malrotation of the femoral component is a cause of patellofemoral maltracking after total knee arthroplasty. Its precise effect on the patellofemoral mechanics has not been well quantified. We have developed an in vitro method to measure the influence of patellar maltracking on contact. Maltracking was induced by progressively rotating the femoral component either internally or externally. The ...
