As part of the PhD carried out at Arcora and the Navier laboratory (2015-2018), a model of an adaptive sunshade was built for the Design Modelling Symposium 2017 in Versailles.
Nickel-titanium shape memory alloys deform silently with temperature, but their deformation remains small (around 5%): the bimetallic effect is used to amplify the movement. The glass-epoxy composite blades carry two shape memory wires, heated electrically by the Joule effect and driven by an Arduino board. This research was presented at the symposium and published in the book Humanizing Digital Reality (Springer, 2017).
