Dances with foils

In-line interferometry of nanometer-scale profiles in flexible electronics has been developed for application on a moving flexible foil.

The ‘dancer’ solution developed by IBS Precision Engineering includes control techniques for tracking in both the travel and the orthogonal direction, and stabilisation techniques for the vertical direction. Foil handling has been optimised to reduce damage to sensitive foils. This Mikroniek article describes how the interferometric system has been demonstrated on a pilot line, handling photovoltaic foils with ultra-low reflectivity, measuring nanometer features – this is a world first.

Order of frictions and stiffnesses…

For lumped systems consisting of different frictions and stiffnesses, there has been confusion in literature about hysteresis curves and virtual play for many decades.
