They designed the incubator in a class called Entrepreneurial Design For Extreme Affordability. The cost of the Embrace incubator is less than one percent of the traditional designs, and rather than isolate the newborn, its design encourages phsyical contact. It operates using hot water to maintain temperature entirely without electricity, making it well-suited to rural areas.
Jane Chen and Rahul Panicker, representing the team at the Echoing Green competition, were awarded the 2008 Echoing Green fellowship.
The team has set up a non-profit called Embrace and plans to launch the incubator in rural India in 2009.
