Researchers Print World’s First Heart-on-a-Chip to Replace Animal Testing


A team of Harvard University researchers has created the first-ever 3D-printed heart-on-a-chip capable of collecting raw data about how strongly a heart is beating.

The device, which is made out of synthetic material, mimics the function and structure of a heart to match the conditions of a disease or individual patient. While researchers say, it is not designed to replace failing organs, but it can be used for scientific studies, reducing our reliance on testing medical treatments on animals.
