Fish from human heart cells: American scientists showed a new invention
Scientists from Harvard presented a robotic fish, for which they used a hybrid material. The creature is able to swim by moving its tail and fins.
The robotic fish, only about a centimeter long, is made of plastic and paper. However, on the tail fins, scientists managed to introduce two layers of cardiomyocytes. These are the heart cells that are responsible for producing heartbeats.
To synthesize cells, Harvard scientists used stem cells. Through simple procedures, "building cells" were synthesized in the laboratory.
The use of heart cells allowed the robotic fish to swim by moving its tail and fins. After placing the creature in the water, one side of the muscle cells contracts, activating the protein, provoking stretching on the opposite side.
According to scientists, their invention is capable of being in a closed cycle state for up to 100 days. It turns out that the fish can move independently without human intervention.
After testing, the robotic device managed to achieve high rates of speed, maneuverability and efficiency. A similar principle of movement is demonstrated by zebrafish in wildlife.
For people interested in robotics, the OXO website has special active lots in the subsection "Constructors". From the proposed options, you can choose not only the characters of science fiction films, but also cute creatures.
