Today I am introducing you to Ekso Bionics , an exoskeleton elite in the United States. Why is it an elite company? Because the company's predecessor was the research branch of Berkeley Robotics and Human Engineering Laboratory at the University of California at Berkeley, almost half of the people came from the American Ivy League school, not to mention its deep military background. Ekso was mainly in the field of exoskeleton design and manufacturing that promoted human function. The main consideration was military use, medical and industrial construction. It was a later event. I thought about this past, but after deep understanding, It is found that Ekso's growth process is still in line with Silicon Valley's consistent technology-based entrepreneurial style, so I will introduce it in detail. As we said before, the idea of ​​using wearable robots to overcome human weaknesses has actually appeared in the mid-1960s. At the time, Marvel Comics published the first "Invincible Iron Man" comic, telling an industrialist named Anthony Edward Stark to become an invincible armored superman after wearing his own mechanical coat. Coincidentally, the US military is also thinking about similar devices. Six months later, Army engineer Sergei J. Zarduni published a paper entitled "Bum puhser: Sports Power Aid." At that time, the US military was also worried about the equipment load of the soldiers. Loading and transporting was one of the two major causes of injury to the US military. Another reason was the damage caused by the improvised explosive device. The heavy casualties caused heavy casualties than any other reason. More. So how do you solve this problem? Now everyone is beginning to realize that they can be solved using exoskeleton robots. Therefore, Zarudny's design inspired the US military, so they began 40 years of exoskeleton science research in this field. It is necessary to know that the research of the US military and the military is to be realistic and to produce research results. It is not acceptable to write a paper. However, at the time of the second industrial revolution, the computer was still quite precious. In addition, physics, the heat of the human body is matched with the amount of work done, but the early exoskeleton is only consumed by standing. A lot of energy. So at the technical level of the time, everyone could only associate the exoskeleton with an energy-driven way like an electric or steam engine. They thought that the only way to drive the exoskeleton was to connect the machine to the power supply via a cable, or to back it up. High-powered gasoline engine, but it is clear that no one will fight and still carry the plug-in board or steam engine at any time. So, the idea is beautiful, the reality is bone-like, but at that time everyone was still enthusiastic. Conduct this study. The key technological breakthroughs occurred in 2004. In fact, it is more accurate to say that it should be a change in research direction. Some young people at the then UC Berkeley Robotics and Ergonomics Laboratory have been thinking about why our exoskeleton consumes so much energy without doing anything useful. Because it is analyzed from common sense, the robot just stands there, and consumes a lot of energy without doing any actual work. And if you look at ourselves, we stand and don't do anything, we don't feel tired. Of course, if you stand for a whole day, you will still get tired, but when we are just standing, it will not be too tired to breathe. So they thought at the time that there must be a way to support our weight like our bone structure, without using a drive, and without consuming a lot of energy. Later, the Institute’s three young people, Hamin Casselni, Nathan Harding and Ras Angord, found this approach and called it ExoHiker. This is actually a simple mechanical component that combines the joints in a certain order, but it transfers weight to the ground through the joints and does not consume energy when standing still. It also leverages gravity and energy recovery technologies. These improvements made it possible to replace the cable with a battery. Thus, the first pair of exoskeletons without any tie was born.
Carbomer is an acrylic resin obtained by cross-linking pentaerythritol with acrylic acid. It is a very important rheological regulator. After neutralization, carbomer is an excellent gel matrix, which has important applications such as thickening suspension. According to the dry product calculation, including carboxylic acid group (-cooh) should be 56.0 % ~ 68.0%.
Common carbopol series include: Carbopol 940, 941, 934, 1342, 980, ETD 2020, AQUA sf-1, Ultrez 21, Ultrez 20, etc.
