USEFUL SIGNALS. Asymmetry in biological systems: "of paramount importance are the physical and biochemical amplification systems that can break symmetry by turning local and transient signals or even noise into stable and system-level asymmetries." Noise transformed to information. https://lnkd.in/eyHMM64 View in LinkedIn

BIOMIMETIC ASYMMETRY. "Constructions of three-dimensional objects with arbitrary shapes and further manipulations of their colours and shapes can provide many potential applications in the field of actuators, and bio-mimetic devices." https://lnkd.in/e37ZsXZ View in LinkedIn

"SMART MATERIALS have attracted much attention due to the ability to change their volume and shape in response to external stimuli." https://lnkd.in/e37ZsXZ View in LinkedIn

PHOTONIC CRYSTALS AND SYMMETRY. "Combining the physical principle of actuators with the basic concept of photonic crystals, colour-tunable 3D photonic actuators were successfully fabricated." New smart materials. https://lnkd.in/e37ZsXZ View in LinkedIn

EXTERNAL FORCE DRIVERS. "Various shapes of these 3D actuating objects were constructed by transforming the programmed 2D structures via bending, twisting and folding mechanisms. These 2D structures were first programmed by breaking the symmetry." https://lnkd.in/e37ZsXZ View in LinkedIn

BIOMIMETIC DEVICES. "The reversible 3D photonic actuators transformed from the programmed 2D structures via the bending, twisting and folding mechanisms may be applied in the field of mechanical actuators, and optoelectronic and bio-mimetic devices." http://www.researchgate.net/profile/Edwin_Thomas/publication/255749505_Three-dimensional_actuators_transformed_from_the_programmed_two-dimensional_structures_via_bending_twisting_and_folding_mechanisms/links/0deec523344479213f000000.pdf View in LinkedIn

NANOPARTICLES ASYMMETRY. "How can a beam of light tell the difference between left and right? Tiny particles have now been coupled to a glass fiber. The particles emit light into the fiber in such a way that it does not travel in both directions, as one would expect. Instead, the light can be directed either to the left or to the right. This has become possible by employing a remarkable physical effect – the spin-orbit coupling of light. This new kind of optical switch has the potential to revolutionize nanophotonics." https://lnkd.in/eFB2gxW View in LinkedIn

BIOMIMICRY OF NACRE. "Stable electronic switches have been fabricated by stacking alternative layers of barium and strontium oxides into a superlattice that breaks inversion symmetry, rather like shell nacre iridescence is caused by calcium and organic material in periodic layers." https://lnkd.in/eneJeki View in LinkedIn

ENDLESS COMPLEXITY. "Nature exhibits endless systems where complex patterns emerge from a-priori structureless objects. For example, leaves and flowers exhibit rippled shapes even though their “vein structure” seems perfectly symmetric. Leaves and flowers are examples of thin bodies that exhibit symmetry breaking even in the absence of external forces." https://lnkd.in/eZr_2gy View in LinkedIn
