According to foreign media reports, in recent years, prosthetic science has developed by leaps and bounds, and it has greatly helped the research of software robots. Swiss researchers have shown that the same technology used to make robotic flexible arms can also be used to make more complex and delicate human organs, such as the heart.
The problem with making artificial hearts is that metal and plastic mechanisms are difficult to fuse with organ tissue or damage the blood due to their unnatural movement. The team led by Nicholas Cohrs, a Ph.D. student at the Swiss Federal Institute of Technology, has created what they call the world's first soft artificial heart, whose pumping mechanism in the silicon chamber works like a real heart. .
Of course, it is not exactly the same as the real heart. The heart of the artificial heart is not a valve, but a ventricle that is inflated and deflated to create a suction, and it is completely sealed. The artificial heart is made using 3D printing , which allows researchers to create complex internal structures using soft, tough materials. The whole heart is basically a whole, so there is no need to worry about how different internal mechanisms can be combined, except for the input and output ports, where blood enters and exits.
In the test, the heart worked well and pumped blood-like fluids all over the body. This artificial heart is a proof-of-concept product that is not printed for actual implantation, so the material from which it is made cannot support thousands of "heartbeats". It can last for about half an hour, depending on your heart rate. If it breaks within the specified time, it means your heartbeat may be quite fast. But obviously, the researchers plan to use better materials and designs to create a heart that can work longer.
Anastasios Petrou, a graduate student of the Swiss Federal Institute of Technology's heart test, said: "As a mechanical engineer, I never thought I could hold a soft heart in my hand. I am right now. This research is very fascinating and I hope to continue to participate in the research and development of artificial heart." (Compile / Golden Deer)
