Scientists have used silicon as a material to make a soft artificial heart by 3D printing. This artificial heart can almost beat like a human heart. This brings us closer to the path of replacing a damaged human heart without transplantation

A step. About 26 million people worldwide suffer from heart failure, but there is a shortage of heart donors, and the implementation of custom artificial hearts will be a valuable solution to this long-term problem. The team from the artificial heart of the Swiss Federal Institute of Technology in Zurich said,

The prototype of this heart can naturally beat for half an hour, and then the matter will start to break down. Now researchers are working hard to improve their new inventions. This silicone heart has a left ventricle and a right ventricle, just like a human heart, with an extra cavity

The chamber, by driving an external pump, serves as the engine for the beating heart. The idea behind this heart is to use pressurized air to inflate the third chamber, allowing blood to pass through the chamber. In order to achieve the purpose of research, the viscosity of the liquid and blood used in the experiment must be

identical. It weighs 390 g (13.8 ounces), has a volume of 679 cm3 (41 cubic inches), and weighs a little heavier, but its size is similar to a normal human heart.

 The research team hopes that the artificial version will eventually replace the existing mechanical heart pump, because the use of mechanical heart may cause complications in the body. Existing mechanical pumps are being used to help people suffering from heart failure recover, or are waiting for the heart

Dirty transplant patients. Each silicone heart can only continue to beat more than 3000 times, and the strength of the material and the performance of the heart need to be significantly improved. But having a soft 3D printed heart that can beat like a human heart is a wonderful and dreamy opening

beginning. "This is just a feasibility test," Cohrs said. "Our goal is not just to provide a heart for implant surgery, but to consider a new direction for the development of artificial hearts." Even if the 3D printed version cannot To replace this most

The key organ may also be promising for studying regeneratively damaged heart tissue. Last month, scientists discovered that genetic programming in sea anemones could unlock a new way to use human stem cells to replace heart tissue. In addition, in this year's

Earlier, a research team at the Worcester Polytechnic Institute (WPI) used spinach leaves to generate functional heart tissue, and it also had venous blood vessels to transport blood.
