“…Artificial morphing and foldable structures have traditionally been fabricated using stiff structural members connected by mechanical joints [1,2,3,4,5,6], resulting in a very challenging manufacturing process at small length scales. In contrast, there are many examples of soft adaptive structures in nature: mimosa leaves fold when touched [7,8]; venus flytraps open and close to catch prey [10]; mechanical expansion and contraction of the pigment-filled sacks in squids result in dynamic color changes [11]. Applying these natural design principles in new ways could result in a novel class of responsive and reconfigurable devices.…”

“…Within 4-5 seconds of stimulation, the pulvini (organs containing motor tissue) execute curvature and the sensitive Mimosa quickly folds its leaflets and pinnae, drooping downward at the petiole attachment. The leaves also droop at night or when exposed to rain or excessive heat, preventing excessive loss of nutrients, and as protection from herbivorous insects or desiccation [83,125].…”

The HCI community has a strong and growing interest in shape-changing interfaces (SCIs) that can offer dynamic affordance. In this context, there is an increasing need for HCI researchers and designers to form close relationships with disciplines such as robotics and material science in order to be able to truly harness the state-of-the-art in morphing technologies. To help these synergies arise, we present Morphino: a card-based toolkit to inspire shape-changing interface designs. Our cards bring together a collection of morphing mechanisms already established in the multidisciplinary literature and illustrate them through familiar examples from nature. We begin by detailing the design of the cards, based on a review of shapechange in nature; then, report on a series of design sessions conducted to demonstrate their usefulness in generating new ideas and in helping end-users gain a better understanding of the possibilities for shape-changing materials.

“…1, the fact that biological structures are built by a number of hierarchical levels, starting from the single cell, allow them preferring helicoidal symmetries, disposing the cells at an angle with respect to the lower ones, as described in Fratzl and Weinkamer (2007). This principle enables on-going correction of defects during self-assembly and ensures that rigidity is only given to the structure when needed, reducing in general energy consumption by a system of reversible folding and extending, well diffused e.g., in flowers and leaves (Patil and Vaijapurkar 2007), but also in proteins (Roder et al 2006).…”

In recent years, bio-inspired approach to design has gained considerable interest between designers, engineers and end-users. However, there are difficulties in introducing bio-inspiration concepts in the university curriculum in that they involve multidisciplinary work, which can only possibly be successfully delivered by a team with integrated competencies. The aim of this work is summarising the results of the first workshop on bio-inspired design carried out at the Hybrid Design Lab of Seconda Università di Napoli, involving Year 2 students of the BSc in Industrial Design. The common theme proposed for their projects was ''Bio-inspired design of sport''. Ideally, a sport item would need to respond to a number of exigencies, including safety, comfort, zero-energy balance and/or use of renewable energy sources, multi-functionality. The common aim of the projects was investigating in which cases bio-inspiration can assist in the fulfilment of the above exigencies. The students were asked to present examples from nature and, via an abstraction process, to apply them to the design of sport items. Finally, they were required to clarify the nature and the extent of bio-inspiration in their projects. Some of the projects, which were considered more interesting and realisable, are reported and briefly commented, especially on the nature, extent and appropriateness of their bio-inspiration. A test for feedback has been given to the students, whose scope, structure and general outcome is also discussed.
