Honorable Mention: 2020 Patents for Humanity -  November 3rd 2020

The Warming Indicator, a phase-change material temperature indicator that improves the Infant Warmer's functionality and safety, was recently recognized with an honorable mention in the 2020 Patents for Humanity awards. The Infant Warmer is a low-cost, convenient, re-usable, and non-electric wrap-around pad that maintains a temperature of 37 degrees Celsius (98.6 degrees Fahrenheit, the average human core temperature) for approximately six hours for a newborn infant. Both technologies are being licensed to a non-profit for scale up in Africa.
