After the Spring Festival this year, folding the phone once again ignited the public's imagination of the phone. In short, the highlight of folding phones is flexibility, that is, they can be bent and folded. NBRH Elastic Material Technology focuses on elastic functional materials and develops terminal electronic products to achieve the goal of stretching and even arbitrary deformation. The company is also becoming a leader in the field of elastic electronic materials.
Conductive wire can be stretched
On the NBRH's display stand, the company's technical director Liu Yiwei took the "rope" and pulled it with force, pulling the 30 cm "rope" to 60 cm. "This is not a simple rope, but a conductive wire. Ordinary wires cannot be stretched, especially after stretching, the resistance should remain basically unchanged." Dr. Liu Yiwei said, this is one of the achievements of NBRH scientific research-elastic wire It is a cable with elastic and conductive functions developed with elastic functional materials.
"Elastic conductive wire can be used for signal transmission of smart sportswear, reducing the probability of breaking the wire during exercise, allowing citizens to exercise more casually and experience better comfort." Liu Yiwei said, Renhe Technology has begun to cooperate with downstream companies ， Apply elastic wires to elastic ear lines, mobile phone charging lines and other fields.
NBRH's technical team is conducting a series of reliability tests. "Under the condition of energization and cyclic stretching, the test monitors the appearance, heat generation and stability of the wire, mainly to control the parameters of the design and application of elastic conductive functional materials and accumulate reliability data. At present, its reliable stretching cycle More than 300,000 times. "Liu Yiwei said that in order to meet the potential needs of other application markets, NBRH has developed elastic wires to a degree after stretching more than 10 times their original length.
Six years ago, NBRH's R & D team mainly came from the elastic sensing technology team of the Institute of Materials Science and Technology of the Chinese Academy of Sciences. In addition to the elastic elastic wires, Renhe Technology also focused on elastic heating, elastic sensors and other fields.
By overcoming elastic heating, Renhe Technology has developed functional fabrics that do not attenuate heating power under tension. "According to this characteristic, it can realize the fitting of the joints of the sports, comfortable heating, and the transformation and upgrading of knee pads and other products, so that the elderly and other groups, especially those with arthritis, can enjoy sports in the cold winter Happiness, and can enjoy the barrier-free and warm service brought by elastic heating knee pads. "Liu Yiwei said.
On the NBRH display stand, Liu Yiwei put on smart gloves to make a "V" shape, and the manipulator next to it also immediately showed a transformation. "With the help of elastic wires, elastic sensors, etc., focusing on human-computer interaction, the gestures can be used to remotely control the manipulator, which provides a new path for applications such as safety production, emergency rescue, and disaster relief." Liu Yiwei said.
Elastic sensors can also be used in the field of medical rehabilitation. In the rehabilitation period, citizens who have breast cancer are very important for the effective exercise of various chest functions. How to monitor the rehabilitation process comfortably, conveniently and interestingly is still a big problem. NBRH has cooperated with downstream enterprises to develop rehabilitation sports games for the related rehabilitation industry. "These game devices use elastic wires, elastic sensors, etc. to capture the various physical functions of patients when they play games, forming a large database, which is convenient for doctors to guide patients to improve their health index." Liu Yiwei said.
In terms of VR, sports games, etc., the game scenes developed by NBRH in cooperation with downstream enterprises can be freely switched between shooting, cycling, and running. At present, these sports and rehabilitation games have launched pilot applications, and the beneficiaries are mainly sports enthusiasts, rehabilitation patients and the elderly.
