Highlight: “Scientists have built a cyborg stingray that swims around using solar-powered heart cells!… From futuristic medical devices to synthetic animals, this coin-sized critter has plenty of potential..Technically known as a “soft robot”, it is comprised of a gold skeleton that is coated with a highly flexible polymer, which is a proxy for a real stingray’s “skin”… Its internal muscles are made of 200,000 genetically-engineered, light-sensitive rat heart cells known as photo-voltaic cardiomyocytes…when these layered cells are exposed to light, they are briefly charged and they contract. This causes the polymer skin to move inwards, which allows the cyborg to swim…”

Insight: Soft robotics and its enormous potential has already been addressed in previous posts of this blog. However, what is additionally interesting to mention about this particular case study is the breakthrough of using controlled motion that combines inert with living systems.

A problem that often arises with motion is the element of scale, powering lets say a human sized object and one that is a few centimeters or even millimeters in size is a very different ball game, not to mention when we start getting into even smaller scales at the cellular or atomic levels. Yet, recently solutions to provide controlled motion even within these ranges has been slowly making successful progress.

A point to make here that applies in many life situations, should it be engineering or management projects, is that scale is often an important parameter that needs to be kept in mind and that requires a customized approach. Often this is underestimated and the common approach of scaling-up without appropriate adjustments or transformations can lead to catastrophic outcomes; in other words, it is not because something works at a smaller scale that it will necessarily (there are exceptions) work on a bigger scale and vice versa…

What is Biomimetics: the field of gaining inspiration from nature first to solve some of our most difficult challenges. Instead of coming up with our own solutions to a problematic, the odds are that species or natural systems on the planet already offer an ultimate solution. This simple fact is also another strong case to preserve species at all cost as the intellectual heritage contained within or through the study of species is both irreplaceable and invaluable…
