Yang Ziguang then inspected other R&D buildings, and was particularly interested in the second-generation exoskeleton robots and bionic robots developed by the Robotics Laboratory of Meixihu University.

The second-generation exoskeleton robot uses lighter composite materials, and the motors and control systems at the joints are more precise, so that the wearer can move freely and make more complex movements.

This is also a very good foundation for the first generation of exoskeleton robots developed by Yang Jie, and the expert team of the laboratory has also developed a full-body exoskeleton on this basis, which can make ordinary people carry a weight of up to 90 kg without feeling the weight.

The electrochemistry laboratory has developed a 100-watt micro fuel cell system for this exoskeleton robot, with a volume of about 3 liters, which can support the exoskeleton robot to work for 100 hours with hydrogen fuel!

In other words, ordinary people can continue to travel 400 kilometers on flat ground at a high load/h speed, and the maximum burst speed can reach 45km/h, which has exceeded the limit speed of the world's top track and field athletes!

This second-generation exoskeleton robot has secretly sent several sets to the military for various extreme tests, and this highest burst speed is still the data provided by the military during the test.

The weight of this micro fuel cell itself is only about six kilograms, and the weight of this exoskeleton robot can still reach 84 kilograms after removing this system!

Compared with the first-generation exoskeleton robot, the second-generation exoskeleton uses more real MEMS sensors and precise mechanical components, which can make the exoskeleton more in line with the range of human body and have higher control accuracy.

Yang Ziguang also heard about MEMS sensors for the first time, and he also inquired about them in detail.

"MEMS is developed on the mature microelectronic technology, integrated circuit technology and processing technology, although the MEMS has channels, holes, cantilever arms, membranes, cavities and other complex structures like previous mechanical parts and tools, but the use of traditional machining technology has not been able to do, can only be achieved by using micro-manufacturing technology similar to the batch processing of integrated circuits. ”

If a single MEMS sensor chip area is 5mmx5mm, an 8-inch silicon wafer can cut out about 1000 MEMS sensor chips, and the cost of each chip can be greatly reduced, and it can be packaged in a chip with other chips after production, which greatly simplifies the process. ”

"The main advantages of MEMS sensors are small size, light weight, low power consumption, high reliability, high sensitivity, easy integration, etc., which are the main force of micro sensors, which are gradually replacing traditional mechanical sensors, and now almost all foreign countries have research in various fields, whether it is consumer electronics, automotive industry, or even aerospace, machinery, chemical and pharmaceutical fields. And now there are mature products abroad, and some of these sensors have begun to be used in many products. ”

"Now the most used is the accelerometer used on the airbag, when the car collides, the sensor produces a relative displacement, the signal processing unit collects the electrical signal generated by the displacement, and triggers the airbag. In addition, our company also uses inkjet microelectromechanical system devices that use bubble expansion on the printing nozzle of the printer. ”

"In addition, MEMS devices can be made from 1 millimeter to 1 micron in length, compared to about 50 microns in diameter of a hair, and these devices can be easily stuffed into mobile phones. ”

"Since this MEMS device is so important, has your Huaxing Group started research and development in this area?"

Yang Jie said: " MEMS is a comprehensive discipline, interdisciplinary phenomenon and obvious, mainly involving micromachining technology, mechanics and solid acoustic wave theory, heat flow theory, electronics, biology, etc., very complex, there is no R & D talent in this area in China, so we previously acquired Norway's Saint Snow company, this company began to develop in the field of micro-electromechanical systems very early, this has a wealth of experience, and now Saint Snow has established a R & D center here, using their technology to develop more sensors。 ”

Yang Ziguang nodded, "The idea of using foreign R&D teams to serve your company is very good, and it is indeed a waste of time to develop it from scratch without a technical foundation." ”

"In order to make our company's mobile phone products more powerful, we are planning to cram more sensors into the mobile phone, including gyroscopes, accelerometers, electronic compasses, magnetometers, barometric pressure meters, distance sensors, ambient light sensors, and microphones should also be made by microelectromechanical machining technology. ”

Yang Jie said: "Some sensors have not yet been made, but Shengsino still has technical experience in this area, and is now working with our engineers to develop various sensors that the company needs." ”

"My requirement for them is that in the future, high-end smartphones will adopt dozens of MEMS devices to achieve multi-mode communication, intelligent identification, navigation and positioning and other functions, increase the intelligence of the mobile phone, and improve the user experience. ”

In fact, these MEMS sensors are not only used in mobile phones, but also wearable and implantable MEMS are an important part of the Internet of Things, and their main function is to provide information directly to users in a more portable, fast and friendly way.

This can be used to expand three major business segments: consumer, medical and industrial.

The products in the consumer field include fitness bracelets and smart watches, while the medical field mainly includes diagnosis, treatment, monitoring and care.

In terms of hearing aids, index detection, and posture monitoring, MEMS can realize almost all sensory functions of the human body, including vision, hearing, taste, smell, touch, etc., and various health indicators can be monitored by combining MEMS and biochemistry. The sampling accuracy, speed and applicability of MEMS can reach a high level, and at the same time, due to its size advantage, it can be directly implanted into the human body, which is a key component of medical auxiliary equipment.

This is an area that Yang Jie attaches great importance to, although the advantages of traditional large-scale medical devices are obvious, that is, high precision, but expensive, difficult to popularize, and generally a device only completes a single function.

In contrast, some medical targets can be used by MEMS technology, taking advantage of its small size, to get deep into the measurement target, reduce costs, and complete more functions while achieving a certain accuracy.
