Surface tension effects in microrobotics.
Surface tension effects in microrobotics.
Abstract : The work presented in this manuscript finds its origin in the switch from assembly toward microassembly, which turned out to be not just a matter of size, but required a much deeper insight on physics governing the considered scales. Therefore, it was necessary to get into knowledges which are usually not familiar to mechanical engineers, such as adhesion science. This document is driven by the underlying idea of using surface tension effects in Microsystems, and falls into three parts. The first part positions our contributions with respect to existing literature, mainly topics such as capillary forces (axial vs. lateral capillary forces, statics vs. dynamics, at scales from millimeter to nanometer). The second part describes the experimental set ups which have been designed to experimentally validate our theoretical work: it essentially consists in force measurement set ups, from nanonewton to newton. The third part describes case studies, including for example assembly watch products, grippers, feeders, hybrid assembly, soil mechanics, electrosprays. The goal was to develop models which are useful to the micromechanical and microrobotician communities. In that sense, we hope that we contributed to feed these communities with capillary forces models which can now be applied in various domains: assembly and packaging, microrobotics, soil mechanics, microfluidics...
