Philippe Ferrari was born in France in 1966. He obtained the Master of Science in Optics and Microwaves from the Grenoble Institute of Technology in 1989, and the PhD, also from the Grenoble Institute of Technology, the 12th of november, 1992, respectively.
Abstract: After a short introduction about wettability of homogenous and heterogenous surfaces, we will show how roughness at microscale can give ‘super’-wetting properties (superomniphobic surfaces) to these surfaces. We will explain how we have fabricated such surfaces using either semiconductor or polymer surfaces. Finally, we will explore several of their features, namely their static wetting, the adhesion of liquids on these surfaces and their robustness.
The second part of the talk is dedicated to the use of these surfaces in various applications using lab-on-a-chip technology. We will introduce several approaches to move droplets on surfaces using electrowetting, photowetting and surface acoustic wave. We will show how to optimize these technologies to make them robust and reduce the energy consumption. Finally, we will present several applications coupling electrowetting and biosensing.
