| summary |
Recent studies involving the passive actuation of zero-energy architectural adaptive systems using programmable materials have addressed the prototyping of wood motion responses by utilizing its latent hygroscopic properties. Most of these systems have focused on mechanisms that are triggered by varying levels of humidity, with very limited efforts addressing the effect of temperature variations; a challenge in hot climatic zones. This paper extends the passive actuation of adaptive systems in climates where humidity and/or temperature variations are dominant. A series of physical experiments were conducted to observe wood veneer sample deflection and motion response behavior under three varying temperature and humidity conditions, with constant values of fiber orientation, lamination, thickness, type of wood, and sample proportion and geometry. The experiment results showed that the coefficient of thermal expansion is an effective parameter, where higher deflection and response speed was recorded under high relative humidity (>80%) upon increase in temperature (>35°). |
