MIT Professor Ioannis Yannas, Inventor of Artificial Skin, Dies at 90

Professor Ioannis V. Yannas, a pioneering physical chemist and engineer, has died at the age of 90. His groundbreaking work led to the invention of artificial skin, revolutionising the treatment of severe burns and chronic wounds. The discovery also marked the first successful example of organ regeneration in adults.

Yannas began his career as a longtime faculty member at MIT, holding roles in Mechanical Engineering and the Harvard-MIT Program in Health Sciences and Technology. His primary focus was induced organ regeneration—finding ways to replace damaged or diseased organs.

In 1969, he teamed up with surgeon John Burke from Massachusetts General Hospital. Together, they developed the first commercially viable artificial skin. Their breakthrough came in 1981 when they announced a material that protected wounds from infection and dehydration while allowing skin cells to regrow.

The product, later named Integra, received FDA approval in 1996. Today, it remains a standard treatment for severe burns, plastic surgery, and long-term skin injuries.

Yannas' artificial skin transformed medical care for burn victims and those with chronic wounds. His research laid the foundation for future advancements in regenerative medicine. The technology continues to save lives and improve recovery outcomes worldwide.
