From November 5 to 10, the 5th China Expo was held in Shanghai. The 6-day China Expo has become a big stage for Chinese and foreign enterprises to "show" their products, highlight their technology, talk about cooperation and talk about friendship. Hundreds of new products, technologies and services have made a concentrated appearance along the Huangpu River. Walking into the exhibition area of this year's China Expo, we can see that they are all hard hitting cutting-edge technologies, which are both novel and fun. Robots and bionic hands. In the future, a flexible intelligent bionic hand will attract attention at this Expo. According to the field staff, the bionic hand can be specially designed for forearm amputees through consciousness control. Chen Yuting, from Shanghai, was the first user of the bionic hand after it entered the Chinese market. At first, she was trying to comb her daughter's hair every day after installation, but she did not expect that she and her bionic hand can make and pack hundreds of duck necks and braised dishes every day, and live a full and energetic life. According to Ossur, this bionic hand is specially designed for forearm amputees. Each finger can move independently, making it more natural and realistic to take objects. The bionic hand has as many as 4 absolutely free control methods, and it has as many as 36 grasping modes to choose from. The size of the grip can be changed. In life, it can not only lift a large box, but also hold a small ball. It can complete such dexterous actions as knocking eggs, peeling rice dumplings, taking moon cakes, picking strawberries, cutting vegetables and cooking rice, writing brush characters, etc. The humanoid robot Tesla Bot previously released on Tesla 2022AIDay also came to the Expo site, but it was only displayed as a model. It is reported that the Tesla robot weighs 73kg and has a built-in 2.3kWh (kilowatt hour) battery pack. The technology it uses is closely related to Tesla car chips, FSD algorithms, construction logic, etc. Tesla Bot can complete basic actions such as walking, climbing stairs, squatting, and taking objects, as well as high-precision actions such as grasping light and thin objects and operating mechanical devices. Since the first Expo, Qualcomm has been the first group of American companies to register for the Expo. This year's Expo, Qualcomm has created a number of interactive experience areas, allowing visitors to experience the "meta universe" enabled by 5G+XR from a distance. The reporter saw that the experiencer can experience the cool "Snapdragon XR Fantasy Tour" in the Galaxy Weir (GVR) sports cockpit, and the on-site audience can also experience the "5G Boundless XR Event Experience" jointly created by Qualcomm and several partners on the VR all-in-one machine. Glass can be rolled, and the heart can wear "bulletproof clothing", which can be unexpected. Have you ever seen glass that can be bent or "rolled"? At the Expo, SCHOTTAG of Germany demonstrated the ultra-thin flexible glass (UTG) with two major technological breakthroughs. This glass can be as thin as 16 microns in the laboratory, which is equivalent to the thickness of two red blood cells. It is understood that this kind of glass is a new kind of glass, which can build a rich and colorful digital consumption experience with micro technology. It is worth mentioning that the thickness of glass is also directly related to its bending capacity. The thinner and tougher the glass is, the closer it is to the "double fold" effect, and the smaller its bending radius is. When the app is used on a folding screen phone
