Keeping newborns warm is essential in medical settings, especially where electricity is unreliable. The Otter newborn warmer, developed by US nonprofit Design that Matters and Vietnamese manufacturer MTTS, addresses this need with innovative design.
Newborn Warmer: Smart Design for Challenging Conditions
The Otter device stands out with its transparent, bassinet-like design, eschewing the complexity of typical medical devices. The device features transparent walls above a robust base with a concise digital display, allowing caregivers easy access and visibility.

Innovative Heating Approach
Instead of a traditional removable water or gel mattress, the Otter uses an integrated heat-conducting polycarbonate surface. This design choice helps avoid mattress replacement issues, minimizes bacteria exposure, and simplifies maintenance. The hospital warmer’s approach to heating ensures consistent warmth without the usual complications.

Efficiency Meets Hygiene
The smooth, seamless interior of the Otter simplifies disinfection processes between patients, prioritizing ease for caregivers. Although it necessitates regular cleaning, the surface design reflects a thoughtful user-centered approach.

Ensuring Consistent Operation with Medical Technology
The Otter’s battery system activates automatically during power outages, providing crucial backup. The portability and ease of use make it a valuable tool in settings where stable power isn’t guaranteed, weighing approximately 11 pounds with batteries.

Simplicity and Functionality
The straightforward display offers vital temperature and battery information, complemented by optional skin-temperature monitoring. The device includes safety alarms for heater, sensor, and power issues, ensuring staff can respond promptly when needed.

Complementary Care and Worldwide Impact
Beyond technology, Otter supports skin-to-skin care practices, providing additional warmth when mothers take necessary breaks. This thoughtful inclusion reflects its practical application in caring contexts, illustrated by deployments in Vietnam, Zambia, and the Philippines.

The Otter device exemplifies innovation with practical design, recognized by the 2026 Seoul Design Award Grand Prize. Its simple yet effective features, like automatic power backups and easy cleaning, make it a critical asset in newborn care where infrastructure challenges prevail. By harnessing medical technology, the device effectively supports the health of newborns worldwide.
