In this recently-posted TEDIndia 2009 video, Jane Chen showcases a infant-size warmer designed to serve as a portable incubator for premature babies and explains how the invention could increase survival rates of preemies in developing countries. Chen says the infant warmer has the potential to save millions of children's lives and that:
The longer term social impact is a reduction in population growth. This seems counter intuitive but it turns out that as infant mortality is reduced population sizes also decrease because parents don’t need to anticipate that their babies are going to die.
Chen and classmates conceived the idea of the portable incubator in Stanford's Entrepreneurial Design for Extreme Affordability course.
