SILICON STINGRAY HOLDS THE KEY TO CREATING AN ARTIFICIAL HUMAN HEART.

Kevin Kit Parker, a Harvard University bioengineering professor, and a group of researchers have created a tiny stingray-shaped silicon softbot that has been implanted with the heart cells of mice. Why? These cells have been genetically engineered to contract when hit with a specific blue light and when they contract, they propel the stingray bot forward! What does this have to do with artificial hearts, you ask? Constructing an artificial heart will use a lot of the same processes as this penny-sized stingray. “Some engineers build things out of aluminum. I build things out of
cells — and I need to practice. So I practice building pumps,” said Parker.
