Résumé

The Saclay group has shown a couple of years ago, that it is possible to improve the measurement of the dynamic signal using high energy surfaces that provide a better wetting [1]. A finite shear elasticity was measured at submillimeter scale in fluids so far considered as purely viscous. A new homemade software has been recently elaborated to improve the measurement of the synchronous reading and visualization of several independent setups (shear strain, stress and normal force sensors with variable resolution time with an option to couple a thermal mapping) [2]. This instrumental coupling has successfully shown that mesoscopic liquids exhibit a change of temperature upon mechanical shear stress [3]. Such study is particularly important for physiological fluids examined in the frame of a collaboration with Prof. U. Windberger [4]. TMAnalysis is a dedicated real-time data acquisition and visualization system, combining camera and multimeters connected to the rheometer [4]. The programming language is Python, combined with EVOCORTEX's irDirectSDK programming API to drive microbolometers.
