Biomimetic file 184: Surface Tension

How to overcome obstacles with minimal risks

1robot_closeupImage source: Seoul National University

Highlight: “a group of engineers, led by a researcher at the Seoul National University, have just created a machine that can jump on water…the engineers studied the mechanics behind the Water Strider, an insect that can easily jump upwards from a pond. It’s an ability that’s poorly understood in insects in general…The trick, according to an analysis of a high-speed film of Water Striders, is to push down on the water with the maximum velocity that the surface tension can take. The further the insect’s leg pushes down, the greater the surface tension that builds under the leg and the better the upward jump. But if the leg pushes too far, the meniscus—the curved water surface—can’t take it and gives way, allowing the leg to sink…it’s necessary to find the optimal balance: push down hard enough to make maximum use of the surface tension, but not so hard that you rupture it…”

Insight: The water tension analogy is an inspiring business philosophy: The faster an obstacle tries to break the water surface the more difficult it is to go through it; as a matter of fact hitting water at high speeds is similar to trying to go through a concrete wall and a guarantied catastrophic outcome.

Is there something blocking you from moving ahead? If so perhaps consider a slower well-thought pass through rather than trying to rush. A slower path is often associated with significantly lesser risks than fast aggressive actions. However, rushing through is always an option and sometimes succeeds (not without risks); The point to retain here is that if one goes too fast, beyond a certain threshold point, than the failure rate increases sharply…

breakeven-diagramDiagram: Economic models follow similar trends: if you try to go too fast in trying to reach the financial break-even point by pushing aspects such as initial cost benchmark, the sales are likely to collapse. It is all about finding the right balance between time and cost…

The adequate planning of the completion speed of any project (time management) is crucially important in its success rate. It can be really tricky to find the right balance that will keep a project on the track of a successful completion. The reality is that in life some situations are subject to risk taking while avoidance is the norm. Which path would you choose?

Highlight: “By combining the mouth muscle from a sea slug with 3D-printed components, researchers have managed to build a biohybrid robot that is able to move with remarkable accuracy and do unusual tasks …The mixture of living tissue and man-made parts is a sector moving into its own…The muscle from the sea slug is controlled by an external electric field, which should mean that in the future scores of the roboslugs could be released to carry out tasks such as locating toxic leaks or even searching the ocean floor for black box data recorders from crashed planes, outlasting conventional robots that would run out of battery before the task is complete…beyond the cellular structure being used in the hybrid robot, the particular motion of sea slugs is of interest…”

Insight: When talking about motion it is most often referring to primary thrust but there is another type being left behind called “auxiliary”. The principle is simple and intends to make use of the primary thrust in order to generate further thrust that make the overall process even more efficient.

A good example would be types of engines used on certain planes, such as an old DC10, where the third engine mounted on the tail is only capturing the energy generated from the two other wing primary engines to generate additional power and gain efficiency.

Swimming sea slugs have a very different way of using auxiliary motion whereby an initial thrust generated by muscle power spreads like a wave throughout its body and is amplified by specialized muscles until it exits, the water pushed in the process  generates the thrust.

There are many situations where part of the energy generated is wasted when it could be amplified with such auxiliary principle and nature offers many good examples of optimization.

Drawing from the auxiliary power analogy, a simple point can be made here: when a favorable situation presents itself, it can be leveraged to get an even greater positive outcome (in other words exploit productive situations to their full potentials as it may take a while to have another shot). By learning to identify hidden opportunities in the surrendering environment, one can maximize the outcomes beyond the expectations; it is an art that can be mastered with surprising results…

Image source: Siemens Robotics Lab/Princeton, New Jersey/USA

Highlight: “researchers at the Princeton, N.J., laboratory of Siemens’Corporate Technology division have developed a collection of 3D-printing robots resembling large spiders (SISpis). The cybernetic arthropods are designed to operate both independently and cooperatively, working together to fabricate custom objects and assemblies…the machines are engineered for the research, development, and testing of algorithms for fabrication, perception, navigation, and collaboration…The most intriguing aspect of the SiSpis machines is the way they work together. As one example, the printing spiders do not carry any material due to their limited load-bearing capacity. Rather, each arthropod is paired with a “sidekick” robot that carries up to two spools of feedstock.”

Insight: Collaboration is key in any type of innovative work. Robotics have evolved greatly in the last decade or so concurrently with networks and notably the internet as the international platform for inter-connectivity. The merging of the two fields: robotics + networks will continue to see a new breed of devices come out that will slowly change our way of life. The wireless age is definitely here to stay and interconnections between devices is set to increase tremendously.

The challenges faced are now in the analysis of large amounts of data and to keep it under control, which some think it is already getting out of hands. Nevertheless another interesting example of biomimetism applied to the field of robotics. Possible applications would include active buildings management, construction sites or disaster reliefs…

Picture source: Biopower systems

Highlight: “The bioSTREAMTM employs a patented oscillating hydrofoil system to extract energy from moving water. For sites that have a peak current speed of 2.5m/s or greater, bioSTREAMTMoffers an environmentally safe and commercially viable source of electricity…An onboard computer continually adjusts the angle of the hydrofoil (fin) relative to the oncoming flow such that the tail and fin system develops a swimming motion. The energy transferred by this side-to-side motion is converted to electricity by O-DriveTM modules installed on the bioSTREAMTM…The ability to streamline and weathervane during periods of excessive flow allow for low-cost construction and competitive generation cost per MWh. A 250kW bioSTREAMTM demonstration project is in development…”

Insight: While conventional spinning blades are the most commonly spread type of tidal generation, it is clearly not suited for every case. There is a lot of potential out there for low cost/low energy systems that mounted in series can provide safe and regular sources of energy for, let say, coastal towns. With the rapid rise of energy storage systems as well as computer processing power (these systems need to be highly dynamic) this type of production is no longer an obsolete addition to other types of traditional energy generation.

It is well established that species movement are efficient, they need to be in order to survive..Therefore it only makes sense that more should be done to study and replicate these movements for efficient and effective energy generation purposes…

VelociRoACH vs cockroach_0

Picture source: Chen Li/University of California, Berkeley

Highlight: “Scientists have modeled a little robot on one of nature’s hardiest insects: the cockroach…it has been retrofitted with a streamlined shell, perfect for helping the bot scrabble through obstacles….The roach uses its natural ‘parkour skillz’, side-rolling to get around barriers it comes across. It is this rotating motion that the team from the University of California, Berkeley, wanted to replicate in their cockroach-inspired robot.”

Insight: As we are only starting the process of replicating natural traits through the use of technology, many aspects of modern robotics have already taken their inspiration from nature. In robotics walking patterns mimicking movements of various animals have significantly contributed to the field should it be through the study of small insects or larger animals such as kangaroos. Other developments of robotics have also made use of simple neuron transmission patterns studied in primitive insects (e.g. cockroaches). From an energy point of view, when studying nature we find that adaptations have often favored developments going towards solutions of lowest energy; in other words species move and behave according to optimal energy efficiency patterns. We should seek more energy efficiency solutions through the study of species…

Biomimetic file 139: Refrigerant free vaccines inspired from sea urchins

Refrigerant free vaccines inspired from sea urchins

Image source: Clip Art image

Highlight: ” CSIRO researchers have come up with a protective seashell-inspired capsule that could cost-effectively and reliably preserve the key active ingredients in vaccines…It mimics a process called biomineralisation where sea urchins grow a hard, protective shell to safeguard their fragile tissue inside. Applying this concept, has led to a molecular-scale shell that grows around and protects fragile biomolecules such as proteins and enzymes.”

Insight: Energy needs (and its cost) often make the difference between a commercially viable initiate and one that is not. In the case of the pharmaceutical industry, a major part of the cost is often due to energy and transport needs in order to keep the products under safe condition rather than the production cost itself. In nature many species anatomy actually provide excellent insulation against the elements in terms of thermal isolation but also other types such as filtering membranes against certain contaminants. We should look in species more for answers when it comes to insulation for diverse applications ranging from medicines to the construction industry…

Biomimetic file 138: Seashell-Inspired Material leading A New Wave Of Safety Gear In Sport

Seashell-Inspired Material leading A New Wave Of Safety Gear In Sport

Picture source: Andy Alderson

Highlight: “Sheffield Hallam University has been developing improved materials for impact protection in sports. The materials have the fascinating and unusual auxetic property (i.e they expend instead of contracting under shock) that can be used in helmets, pads, guards, gloves, mats and barriers…the inspiration for the current work on auxetic materials for improved impact protection equipment in sports comes from the ultimate natural armour protection system: the humble seashell.”

Insight: Some species in the animal kingdom have highly adapted exoskeletons that not only support their structure but also act as a protective armour against the elements and predators. The combination of light weight and strength are two aspects commonly found in species skeleton structures. The properties in certain species structures (down to the molecular level) such as shrimp shells or oysters  have already led to practical innovations in sectors such as aerospace or construction where the strength/weight ratio of materials is a rising challenge. It is likely that the inspirations for future structures and materials will be found within species…

Insight:

While copying natural systems is a field only at its earliest stage, sometimes utilizing biological systems within engineered structures can also lead to interesting outcomes.

Mimicking natural processes or systems is often underestimated in terms of its complexity. Even simple systems that are omnipresent in our surrounding environment (e.g. photosynthesis) are actually extremely difficult to replicate given our current technologies.

While there are some success stories of copying natural systems (to some extent)  utilizing engineering practices, such replications while still more efficient than other human made practices are often under-performing the natural systems.

Another approach to bio-mimicry is a hybrid one in which systems judged too complex to replicate are actually combined with artificial ones. This synergy can be extremely complex but is starting to show successful applications. For instance researchers after years of trials are now able to isolate specific synaptic electrical signals emitted by the human brain to send orders to artificial prostheses.  This technology makes artificial body parts control such as a hand or a leg possible with direct input from the brain.

This specific case study is only a realization that in our current state of technological advancements we are simply unable to replicate many relatively simple natural processes which still outsmart our abilities. Until such capabilities are met perhaps a faster way of advancement in the field of bio-mimicry would be the hybrid approach of utilizing parts of natural systems combined with engineering applications.

We tend to pride ourselves through our technological breakthroughs as an advanced society but if we start to compare our capabilities with what nature provides all around in our environment we then come to the simple realization that we are actually not so advanced at all..
