A robot shaped like a band-aid that moves within the human body under the control of a magnetic field. In 1966, a film "Singular Journey" won an Oscar. It tells the story of five doctors who narrowed themselves into the patient and performed surgery. This seemingly unrestrained imagination 50 years ago, and now scientists are studying how to turn it into reality, of course, not the people out, but to make micro-robots into the body for various operations and treatment. "The purpose of our research is to target future traumatic or minimally invasive surgery," said Hu Wenqi, a researcher at the Max Planck Institute for Intelligent Systems in Germany. However, how to cross the complex environment of the human body is a very difficult task for robots of only millimeters or even micrometers. “The micro-robot we are doing now demonstrates the good athletic ability in various environments and various surfaces, which makes it have the potential to adapt to the complex environment inside the human body.†The micro-robot designed by Hu Wenqi and his team looks very ordinary, like a black ultra-miniature “band-aid†with a length and width of only 3.7 mm and 1.5 mm respectively. The production process looks simple as a girl. Mask. However, under the control of the magnetic field, it can perform various prescribed actions, swim in a liquid environment, walk or climb, or roll, or jump in a solid environment, and shuttle through the pipe, it can even pick up a small The items are sent to the designated location, which is not available in previous micro-robots. “Most of the previous micro-robots were able to perform one or two actions, and our robots could perform seven actions,†Hu Wenqi said. Recently, Hu Wenqi, as the first author, published his research results in the journal Nature. Inspiration from nature In the German Max Planck Institute for Intelligent Systems, where Hu Wenqi is located, it is common to find inspiration for solving problems from nature's creatures. Some people observe large animals such as cats, dogs, and bats, some from small bacteria. Get inspired in the sport. Hu Wenqi's design of micro-robots is also based on observations and research on various biological movements. When a small micro-robot is completely submerged in water, its stroke is very similar to that of a jellyfish; on a regular surface, the robot can roll quickly, just like a caterpillar is escaping its predator; when it is on an irregular surface The robot will simulate the pace of the ruler. First, use the front end to support the ground, adjust the angle, pull the rear end forward, and then use the rear end to re-stretch the front end; in a small pipe, the robot will vibrate like a caterpillar. Passing through; when encountering obstacles, the robot jumps like a nematode. The simulation of biological movements allows the simple robots to acquire super powers in different media. “The former micro-robots were mostly in a medium, such as in water.†However, the seemingly normal water surface is like a mountain top for micro-robots. “The liquid surface has a strong tension. Once many micro-robots arrive at the interface, they 'sacrifice'.†The movement of the different interfaces is unique to this small robot. In terms of physical properties, in addition to the environment of solid-liquid gas and its interface, there are more complex environments in the human body, such as granular media in the stomach. In the next work, Hu Wenqi will continue to draw inspiration from animals to achieve the sporting ability of a more complex environment. In vivo treatment "We are doing micro-flexible robots, and the longer-term goal of aiming is to have minimal trauma or minimally invasive surgery," Hu Wenqi said. Nowadays, many operations still need to open relatively large wounds, such as tumor resection, which not only has a greater impact on the human body, but also a long process after recovery. "What our team envisions is that this may not be necessary in the future. Surgery can't go on like this forever, and it needs to be developed," Hu Wenqi said. "We want this miniaturized robot to enter through a small opening in the human body." For example, in the cardiovascular system, it can be injected directly into the blood vessel, allowing it to directly act on the desired location for treatment." At present, many doctors in the United States and Europe have begun to take an interest in this. The simplest thing they think of, and the earliest practical use is the delivery of drugs. "For example, the digestive doctors, they want to make this small robot the same structure as the sponge, that is, on our basis, there are some adsorption capabilities. The drug is sucked in, through the movement, into the stomach or the digestive tract. From the current medical point of view, the drug needs to pass through the layers of the body to achieve the targeted position, during which the drug dose is greatly attenuated. The dose of the drug that eventually reaches the targeted site is insufficient to achieve a therapeutic effect. "In the future, the robot can reach the designated location and release the drug," Hu Wenqi said. Simulating movement in the stomach Moreover, our robots can be observed through traditional medical imaging equipment, which can track the position and movement of the robot inside the human body and control it accordingly. "Because the magnetic resonance equipment provides the magnetic field, our robot is also a magnetic drive, so the future we imagine is that when the robot enters the human body, the nuclear magnetic resonance equipment can be used not only for imaging, but also for some treatment. Our next step is to do the work." Each operation has a fixed process and a fixed need. "We hope that this robot can optimize the treatment process according to the condition of each disease, so that the treatment effect is better and the pain of the patient is smaller." Hu Wenqi said. Homemade mask-like making process "We don't have much research on the production process yet, but we put more energy into the study of athletic ability." Hu Wenqi said. At present, the micro-robot developed by Hu Wenqi's team uses biocompatible silicone rubber with magnetic NdFeB particles with an average diameter of 5 microns. At present, its production process is somewhat similar to the mask made by girls. The resulting micro-robot is 3.7 mm long, 1.5 mm wide and approximately 185 microns thick. "The next step is to make the robot smaller, making it a sub-millimeter, a few hundred microns." Hu Wenqi said, "At the same time, we are also looking for other soft materials, similar to the extraction of automatic substances such as seaweed, The material of the plant is what we plan to use next." In the future, Hu Wenqi and his team will not only study how to make micro-robots smaller and smaller, they also hope that micro-robots can achieve automatic degradation after completing their mission. By then, perhaps it is possible to achieve a "singular journey" in the human body. Elf Bar has been making an effort on innovative product via a smart heating system.
