According to foreign media reports, prosthetics have become more and more intelligent, thanks to advanced sensors and light-duty motors, and this week, such prostheses have achieved the most significant breakthrough: the latest bionic legs can be completely user Controlled by brain consciousness. Although the prosthetic research that can be controlled by the brain has been underway for four years, the research team published details of the research progress in an article published in the New England Journal of Medicine today.
The research work was done at the Chicago Rehabilitation Institute, which has a research center dedicated to bionics. According to the institute, the prosthetic leg can be easily switched between different types of actions based on the user's mind. Zac Vawter, the tester using the prosthetic leg, said in a statement, "This kind of prosthetic leg allows me to walk up and down the stairs accurately, and even perform actions according to my ideas. For me and all This is a huge milestone for amputees."
Although the brain-consciously controlled fake arm is already on the market, the brain-consciously controlled prosthetic leg is a completely different thing. Levi Hargrove, the researcher's lead researcher, told the media, "If there is a mistake or fault that causes the user to fall, it can be catastrophic. We hope to avoid this at all costs. Occurs." However, such a brain-conscious prosthetic leg seems to operate smoothly. Last year, the research team announced its progress under the leadership of Water, and the user wearing the fake leg climbed the 103-story Chicago Willis Tower.
This technology works like a method of bionic arms that researchers have developed. The nerves leading to the patient's damaged muscles are re-healthy muscles, and the sensor is placed nearby to read the information expressed by the nerves. The prosthetic leg then accepts this information and translates it into an action that the user initially consciously desires.
The Chicago Rehabilitation Institute has received $8 million in investment from the US Army to develop research on brain-controlled prosthetic legs. The US Department of Defense is now very interested in prosthetic research that is progressing, especially with regard to such a method that can help injured soldiers. And, this is more than just a defense-funded project. The institute also received funding from DARPA to improve the speed of the entire neural interface, which will help the Institute's bionic legs and DARPA's own brain-controlled Bionic arm research progress.
The Chicago Rehabilitation Institute hopes to have its bionic legs available for any user in the next five years. Of course, the cost may be a big problem, but Hargrove said that they are trying to keep prices to the lowest possible level. He told the media, "We will use the technological advances of related industries to ensure that we use low-priced accessories." At present, the price of such fake arms is between 20,000 US dollars and 120,000 US dollars.
Now, Walter is the only person who wears a brain-controlled prosthetic leg developed by the Chicago Rehabilitation Institute. However, if such a prosthetic leg walks as he described, this would be a subversion of the prior art. He told the media, "This has made amazing progress."
Double Packed Yellow Waxy Corn Cob
The most common waxy and sweet corn market, waxy corn nutrient content is higher than ordinary corn, contains 70-75% starch (and almost all amylose), more than 10% protein, 4-5% fat and 2% multivitamin, has more grain, VA, VB1, VB2 than rice protein, fat and VB2 highest content. Yellow corn also contains carotenoids like rice and wheat. The molecular weight of glutinous corn starch is more than 10 times smaller than that of ordinary corn. The starch makes glutinous rice sticky and soft, which is softer than that of ordinary hard corn. It has more than 20 percent more digestibility than regular corn and is suitable for people with irregular teeth. At the same time, the amylose (a polysaccharide) content is very high, not suitable for diabetics.
Waxy corn is also called sticky corn. The grain has a coarse, waxy endosperm that resembles a glossy, transparent grain, such as a hard, dented corn. Its chemical and physical properties are controlled by a recessive gene located on chromosome 9. 100% of the starch in the endosperm is amylose.
