Tencent Digital (Databoy) Cho Dong-woo, professor of mechanical engineering at Pohang University of Technology, South Korea and Dr. Choi Young-jin of bioengineering work together to successfully create the world’s first artificial muscle using 3D cell printing technology and bio-ink. Human muscle is almost the same.
Using 3D printing technology to create personal medical equipment and manufacturing artificial organs, many researchers have already done. Since materials are harmful to the human body, it is still a long way from replacing artificial organs with real human organs. The research results of Korean universities are worth paying attention because the newly-manufactured artificial muscles can mimic the structure and characteristics of skeletal muscles. Skeletal muscle is a muscle near the bone in the human body and exists in many forms. Some muscles are unconscious muscles, such as the heart, which cannot control muscle activity. Skeletal muscles are different. Under electrical signal stimulation, skeletal muscles can perform many actions with different strengths.
If you want to replace skeletal muscle, artificial muscle must have a variety of different forms and sizes, can easily contract the diastolic. In the past, researchers used artificial muscles to fill materials into molds (such as collagen). However, this method was time-consuming and inaccurate for patients.
Using artificial methods to make artificial muscles and unable to regulate cells, these cells can make muscle regeneration indispensable. There are also limitations on the materials used in the manufacturing process. The materials do not harm the human body. The materials also help the growth of true muscle cells and provide an environment for the regeneration of muscle fibers.
It is precisely for this reason that researchers at the University of Korea will find another way to extract bio-ink from real skeletal muscles and then use artificial muscles with 3D cell printing technology. Artificial muscles made with the new method have better retractility and can receive electrical signals effectively, simulating the function of real muscles. Professor Cho Dong-woo said: "If you use 3D cell printing technology and muscle bio-ink manufacturing, artificial muscle can simulate the structure and function of real muscles, and ultimately can be used to develop new drugs to treat muscle diseases."

The lithium Battery Protection Board is the charge and discharge protection for the series-connected lithium battery pack; when fully charged, it can ensure that the voltage difference between the individual cells is less than the set value (generally ±20mV), so as to realize the equal charge of each single cell of the battery pack. , effectively improving the charging effect in the series charging mode; at the same time, it detects the overvoltage, undervoltage, overcurrent, short circuit, and overtemperature status of each single cell in the battery pack to protect and prolong the battery life; undervoltage protection makes each A single-cell battery is used to avoid damage to the battery due to overdischarge.
