A plant tendril mimic soft actuator with phototunable bending and chiral twisting motion modes
In nature, plant tendrils can produce two fundamental motion modes, bending and chiral twisting (helical curling) distortions, under the stimuli of sunlight, humidity, wetting or other atmospheric conditions. To date, many artificial plant-like mechanical machines have been developed. Although some previously reported materials could realize bending or chiral twisting through tailoring the samp...
متن کاملInextensible Networks with Bending and Twisting Effects
Families of inextensible fibers forming a surface are considered. Each fiber supports a twisting couple proportional to the torsion of the fiber. The strain energy density is written in an additive form, such that the contributions due to shearing, twisting and bending effects are taken into account separately. The equilibrium equations, here obtained, are a particular case of the ones obtained...
متن کاملA plant-inspired robot with soft differential bending capabilities.
We present the design and development of a plant-inspired robot, named Plantoid, with sensorized robotic roots. Natural roots have a multi-sensing capability and show a soft bending behaviour to follow or escape from various environmental parameters (i.e., tropisms). Analogously, we implement soft bending capabilities in our robotic roots by designing and integrating soft spring-based actuation...
متن کاملSoft Modes associated with Chiral Transition at Finite Temperature
Using a novel resummation procedure of thermal loops, real-time correlations in the scalar and pseudo-scalar channels are studied in the O(4) linear σ model at finite temperature. A threshold enhancement of the spectral function in the scalar channel is shown to be a noticeable precritical phenomenon of the chiral phase transition.

متن کاملTwisting and bending stress in DNA minicircles.
The interplay between bending of the molecule axis and appearance of disruptions in circular DNA molecules, with ∼100 base pairs, is addressed. Three minicircles with different radii and almost equal contents of AT and GC pairs are investigated. The DNA sequences are modeled by a mesoscopic Hamiltonian which describes the essential interactions in the helix at the level of the base pair and inc...
