Abstract

Sun-shading Plant-inspired skin can use plant actuation principles to develop reversible motions. This paper will triangulate the intersection between plant actuation principles, their morphology and low energy strategies, to integrate the underlying mechanisms in responsive dynamic shading skins. This paper will investigate the non-autonomous reversible plant movements to develop elastic kinetic solar screens. New approach of soft mechanics found inspiration in plant movements for pliable structures in architecture. Interestingly, global flexibility is often achieved through the adaptive behaviour of plant that change its morphological features by acting as living hinges and allowing for elastic deformations. These motion patterns are found in nastic structures which are very promising as natural actuators.By studying how plant species take advantage of mechanical, compositional and structural gradients toperform mobility with minimal energy use, it is possible to learn how to integrate these properties into the design of kinetic shading solar screens. The focus of this review is to understand the soft mechanics approach and its applications on responsive shading skins. A critical review of the current progress in mechanical properties and actuation principles of nastic plant movements is illustrated.
