“…Developed as a compromise between hot-films and hotwires and with the objective of real flight application, the high temperature gradient micro-sensors designed at IEMN is composed of wall suspended wires, mechanically supported by periodic perpendicular micro-bridges ( [11], [12]). The sensors were successfully tested in various configurations: in low [13] and high-speed wind tunnels [14] and on models [15]. In this paper, we present the utilization of such micro-sensors for real flight experiments realized on a microlight aircraft.…”

This paper reports the realization of thermal MEMS (Micro Electro-Mechanical Systems) sensors designed for wall shear stress measurement during real flight on a microlight aircraft. Based on constant temperature anemometry and calorimetric principle, the micro-sensors measure the viscous shear stress occurring at the wall of a structure interacting with a fluid flow and detect the flow direction. A proper packaging was realized for ensuring a flush but robust integration of the devices on a pod fixed on a microlight aircraft. Real flight-testing demonstrated the ability of the micro-sensors to realize aerodynamic measurements up to 250 km/h on the microlight aircraft.

Experimental flow visualization is a valuable tool for analyzing microfluidics and nanofluidics in a wide variety of applications. Since the late 1990s, considerable advances in optical methods and image postprocessing techniques have improved direct optical measurements, resulting in an accurate qualitative and quantitative understanding of transport phenomena in lab-on-a-chip capillaries. In this study, a comparison of different optical measurement techniques is presented. The state-of-the-art development of particle image velocimetry to date, particularly in microscale applications, is reviewed here in detail. This study reviews novel approaches for estimating velocity field measurements with high precision within interrogation windows. Different regularization terms are discussed to demonstrate their capability for particle displacement optimization. The discussion shows how single- and multi-camera optical techniques provide two-dimensional and three-component velocity fields. The performance of each method is compared by highlighting its advantages and limitations. Finally, the feasibility of micro resolution particle image velocimetry in bioapplications is overviewed.
