This account reviews our recent research activities in the field of CO2 reduction. We discuss here the potential of the bio-inspired approach for the design of electrocatalytic systems for small molecule transformation. Exploiting the billion years of evolution of natural systems, we illustrate the potential of bio-inspired strategies across multiple scales to design catalytic systems. We demonstrate in particular how the shape of biological systems as well as enzymatic active sites and their environment can constitute effective sources of inspiration for the design of electrocatalysts with im

Abstract Recent observations of wingless animals, including jumping nematodes, springtails, insects, and wingless vertebrates like geckos, snakes, and salamanders, have shown that their adaptations and body morphing are essential for rapid self-righting and controlled landing. These skills can reduce the risk of physical damage during collision, minimize recoil during landing, and allow for a quick escape response to minimize predation risk. The size, mass distribution, and speed of an animal determine its self-righting method, with larger animals depending on the conservation of angular momen

We turn to natural systems for inspiration since they inherently demonstrate network pruning with the consequence of yielding more efficient networks for a specific set of tasks. This

Abstract Some weakly electric fish can use electric signals to interact and communicate with each other in dark and complex underwater environments where traditional underwater communication fails. In our previous work, we developed a bio-inspired electrocommunication system (BECS) that serves as an effective alternative to traditional methods in this challenging underwater scenario performing communication at a speed of approximately 1200 bps (bits per second) within approximately 3 m. In this study, a novel underwater wireless communication system (BECS-II) is proposed to upgrade the BECS wi

As result of advancements in DNA technology, nearly any two- or three-dimensional architecture may now be precisely built. The selection of DNA sequences creates new opportunities to predictably generate the structure and size of anodized monomolecular assemblies, which is crucial for successful self-assembly. Designer nucleoside analogues can be added to DNA nonmaterial’s to further functionalize them with accessible groups that affect their activity.

Abstract Inspired by the sliding behavior of gecko feet during climbing, the contribution of shear effect to the self-cleaning performance of a bio-inspired micropillar arrayed surface is studied through a load-shear-pull contact process. It is found that the self-cleaning efficiency can be enhanced significantly by shear, which also depends on the microparticle sizes. For the case of relatively large and small microparticles, the self-cleaning efficiency increases first and then almost keeps a constant with the increase of the shear distance at different preload. For medium microparticles, sh

Abstract Insect compound eyes are optical systems with small volume and compact structure. The ommatidium in the dorsal rim area of some insects have polarized vision, which can perceive the polarization pattern of the sky and provide navigation information for themselves. In this paper, inspired by the polarization-sensitive compound eyes of insects, a bio-inspired polarization navigation sensor based on artificial compound eyes is designed. The sensor consists of an artificial compound eye, an integrated polarization detector and an integrated circuit. The optical path of the sensor uses the

AbstractHigh-speed locomotion is an essential survival strategy for animals, allowing populating harsh and unpredictable environments. Bio-inspired soft robots equally benefit from versatile and ultrafast motion but require appropriate driving mechanisms and device designs. Here, we present a class of small-scale soft electromagnetic robots made of curved elastomeric bilayers, driven by Lorentz forces acting on embedded printed liquid metal channels carrying alternating currents with driving voltages of several volts in a static magnetic field.

Abstract First-row transition metal-based catalysts have been developed for the oxygen evolution reaction (OER) during the past years, however, such catalysts typically operate at overpotentials (η) significantly above thermodynamic requirements. Here, we report an iron/nickel terephthalate coordination polymer on nickel form (NiFeCP/NF) as catalyst for OER, in which both coordinated and uncoordinated carboxylates were maintained after electrolysis. NiFeCP/NF exhibits outstanding electro-catalytic OER activity with a low overpotential of 188 mV at 10 mA cm−2 in 1.0 KOH, with a small Tafel slop

Abstract Gripping slippery and flexible tissues during Minimal Invasive Surgery is often challenging using a conventional tissue gripper. A force grip has to compensate for the low friction coefficient between the gripper's jaws and the tissue surface. This study focuses on the development of a suction gripper. This device applies a pressure difference to grip the target tissue without the need to enclose it. Inspiration is taken from biological suction discs, as these are able to attach to a wide variety of substrates, varying from soft and slimy surfaces to rigid and rough rocks. Our bio-ins

Abstract The inverted flag configuration is inspired by biological structures (e.g., leaves on a tree branch), showing rich dynamics associated with instabilities at lower flow speeds than the regular flag configuration. In the biological counterpart, the arrangement of leaves and twigs on foliage creates a complex interacting environment that promotes certain dynamic fluttering modes. While enabling a large amplitude response for reduced flow speeds is advantageous in emerging fields such as energy harvesting; still, little is known about the consequence of such interactions.

AbstractNeuromorphic computing, a computing paradigm inspired by the human brain, enables energy-efficient and fast artificial neural networks. To process information, neuromorphic computing directly mimics the operation of biological neurons in a human brain. To effectively imitate biological neurons with electrical devices, memristor-based artificial neurons attract attention because of their simple structure, energy efficiency, and excellent scalability. However, memristor’s non-reliability issues have been one of the main obstacles for the development of memristor-based artificial neurons

Abstract Peptide self-assemblies are a natural template for designing bio-inspired functional materials given the extensive characterisation of neurodegenerative and non-disease biological amyloid protein assemblies and advances in rational, modelling-led materials design. These bioinspired materials employ design rules obtained from known aggregation-prone peptides or de novo screening for sequences most amenable to self-assemble functional nanostructures.
