Beating like a real heart. The first completely artificial, flexible heart made of silicone was recently developed by researchers at the ETH center in Zurich.
Although this research is a huge breakthrough, for now the heart can only work for approximately 3,000 heartbeats. That is about forty-five minutes. A real heart can beat 100,000 times a day. Its weight is 390 grams and it has the same size and capacity (approximately 679cm3) as a human heart. A perfect imitation.
There is still much progress to be made, but this is undoubtedly the first step in a surprising future for medicine.
