“…In this system an actuation output displacement of over 1mm is achieved, while the piezoelectric actuator exhibit an output displacement of 45µm : this amounts to a KAR of about 25. In [148], a space deployable and adaptive structure inspired by the bilayer effect caused by the differential turgor pressure in plant cells (see 2.1.2) is proposed. An array of inflatable cells connected by MEMS valves with a central electrical command can change its curvature or reach more complex shapes by inflating or deflating specific cells.…”

While plants are primarily sessile at the organismal level, they do exhibit a vast array of movements at the organ or sub-organ level. These movements can occur for reasons as diverse as seed dispersal, nutrition, protection or pollination. Their advanced mechanisms generate a myriad of movement typologies, many of which are not fully understood. In recent years, there has been a renewal of interest in understanding the mechanical behavior of plants from an engineering perspective, with an interest in developing novel applications by up-sizing these mechanisms from the micro-to the macro-scale. This literature review identifies the main strategies used by plants to create and amplify movements and anatomize the most recent mechanical understanding of compliant engineering mechanics. The paper ultimately demonstrates that plant movements, rooted in compliance and multi-functionality, can effectively inspire better kinematic/adaptive structures and materials. In plants, the actuators and the deployment structures are fused into a single system. The understanding of those natural movements therefore starts with an exploration of mechanisms at the origins of movements. Plant movements, whether slow or fast, active or passive, reversible or irreversible, are presented and detailed for their mechanical significance. With a focus on displacement amplification, the most recent promising strategies for actuation and adaptive systems are examined with respect to the mechanical principles of shape morphing plant tissues.

“…One option would be the use of micropumps inbetween two cells to transfer air molecules inbetween them, therefore always one cell would be inflating and the other deflating. Another option is the use of valves between all the cells with a central pressure source 7 . The system of valves would transfer the airmass to the cell which needed to be actuated.…”
