Stylus and Optical Profilometry Webinars

Stylus Profiling Metrology for Soft Matter: Film Thickness and Depth for Flexible Electronic and Microfluidic Devices

Learn how to accurately and repeatably measure thickness and depth of fragile thin-film surfaces

Explore the most innovative capabilities of advanced stylus profilers.

In this webinar, stylus profilometry expert Samuel Lesko, PhD, discusses how stylus profilers can be used to characterize a wide range of soft and thin materials crucial for flexible electronics and microfluidic devices.

Viewers can expect to gain new insight into:

  • Why advanced stylus profiler techniques provide an optimal thickness metrology solution for thin films;
  • The benefits and advantages of using advanced surface profilometry for thin film analysis; and
  • The range of nanometer- to millimeter-scale thickness metrology applications made possible by advanced surface profiler techniques and instrumentation.

Webinar Summary

Driven by automation for production, inter-connectivity demands and energy harvesting, Internet of Things (IoT) and green energy solutions are booming. Researchers from both academia and industries actively seek new processes as well as novel materials to develop light and low-cost flexible electronics, or self-power driven and recyclable sensors. Recent innovative devices notably contain stacks of multi-layer thin films with new alloy organic and/or intermetallic materials that are extremely fragile.

In this webinar, Samuel Lesko, PhD, showcases how advanced stylus profiling further extends to fragile surfaces such as PEDOT:PSS photovoltaic materials, PDMS microfluidic channels or amorphous-indium-gallium-zinc-oxide (IGZO) transistors. He shows an example of PDMS microfluidic structures, where the stylus is aligned using optical videos and motorized feeders to achieve reproducible nanometer-level results even on soft, sticky surfaces.
