Scientists at the National Institute of science and technology in Ulsan, South Korea, have been studying the tentacles of octopus. They found a stress system on the tentacles of the cephalopod, which consists of a sucker and a muscle around it. When Octopus wants to catch something, a group of muscles will control the contraction of the sucker, and the cavity on the wall will become smaller and generate suction. When opening the thing, another group of muscles will be used, and the opposite process will release the sucker pressure to move.
Hyunhub Ko， He is the leader of the research, and he believes that this applied research has a wide range of prospects. From the circuit, the pressure sensor to the medical sticky pad, the adsorption system without glue will change our understanding of the nanoscale printing.
Ko and his team felt that the best way to copy an octopus sucker was to use heat. They chose poly two methoxy silicone rubber and silicon material to create a nano thin slice containing sucker shaped array, which has stomata on the chip, and its function is similar to that of the octopus sucker, and it remains open at normal room temperature. When this piece of thin film is heated to 32, the hole will automatically shrink to produce a suction.
At present, the Ko team is trying to apply their nanomaterials to semiconductor nanoribbons, which can make microchips. Ko hopes that the application scenario can be further extended to the field of medical adhesives, such as sensors used to fix heart rate instruments. The nanoscale film, which does not require glue, can reduce the allergic reaction that may be produced by the patient.
