![]() ![]() The loss of appendages can severely affect a person’s quality of life. This material is expected to pave the way for the development of robots and various applications in advanced manufacturing and engineering. Because the electro-tendon can simultaneously transmit signals and force from the sensing and actuating systems, we use it to replace the single functional tendon in humanoid robotic hand to perform grasping functions without additional wiring and circuit components. The electro-tendon, mechanically toughened by single-wall carbon nanotubes (SWCNTs) and electrically enhanced by PEDOT:PSS, can withstand more than 40,000 bending-stretching cycles without changes in conductivity. Here, we report a super tough electro-tendon based on spider silk which has a toughness of 420 MJ/m 3 and conductivity of 1,077 S/cm. However, current tendon fibers have low toughness and suffer from large friction, limiting the further development of tendon-driven robotic hands. However, as a hint to obtain a method to produce stronger synthetic fibers, it seems that there is a possibility that the result of this research will be used to a great extent.Compared to transmission systems based on shafts and gears, tendon-driven systems offer a simpler and more dexterous way to transmit actuation force in robotic hands. However, in this experiment, it was found that four giant clams that were sprayed with graphene / carbon nanotube-containing water died immediately after spraying, and a method to effectively collect and produce carbon-containing high-intensity spider's webs was found Is not. ![]() Applying a spider's thread containing graphene and carbon nanotubes this time, a spectacular dream device has been devised that may be able to create a huge net that can catch a crashing airplane on the ground. Where the spider's thread is excellent, it is the place where the natural material has the highest level of strength, while having elasticity at the same time. Emiliano Repole, a research team who gave surprising results, "From the phenomenal strength it can be said that it is hard to imagine that carbon nanotubes or graphene was simply coated on the surface of a spider's web.As for the hypothesis, There is a possibility that carbonaceous material was taken in and spirally kneaded in spider's yarn, but detailed mechanism is not well understood yet. This figure is the highest strength among all the natural substances born so far, and the strongest fiber on earth is born now because it has toughness exceeding "Kevlar 49" which is one of the strongest synthetic fibers It is said that it did.ĭr. The strength increased more than when adding carbon nanotube-added water, the strength was about 3.5 times that of the spider's spider of the strongest natural substance, and the Young's modulus reached 47.8 GP. In order to investigate which of graphene and carbon nanotube is effective for increasing the strength, we collected five young spider mice and tested them, and as a result, even when any substance was mixed, the strength was greatly improved. So Punyo and others live in Italy Yulegumo, We adopted a straightforward method of spraying water mixed with graphene and carbon nanotubes. Research teams such as Professor Nicola Maria Punho of Trent University in Italy should not mix graphene and carbon nanotubes in order to further improve the strength of the spider's string of the highest level of strength in natural materials I thought. ![]() Spiders sprayed with graphene or carbon nanotubes spin super silk - life - New Scientist ![]() Spiders Ingest Nanotubes, Then Weave Silk Reinforced with Carbon | MIT Technology Review Silk reinforced with graphene or carbon nanotubes spun by spiders Italian scientists wiped the water mixed with graphene and carbon nanotubes with spiders to try out simple questions as to what will happen if these natural strongest substances and artificial strongest substances are mixed together, The thread of birth was born. Meanwhile, attracting attention in recent years as a high-performance material boasting the highest level of strength with artificial substances carbon nanotubeYa Grapheneis.
