Scientists develop fast-pumping artificial foam heart
Scientists have developed a soft, foam-based artificial heart which can pump at a faster rate than any similar alternatives. The proof-of-concept heart is made of flexible, porous silicone and is an example of soft robotics, which move by allowing compressed air to flow through the material, according to New Scientist magazine. Many of the current artificial hearts approved by the U.S. Food and Drug Administration (FDA), which tests medical devices, are hard devices that are attached to external pumps, such as the SynCardia Total Artificial Heart.
