23 million Low Birth Weight babies are born each year across the world, a staggering 96% of whom are born in developing countries. Due to their small size, these babies are vulnerable to neonatal hypothermia, one of the leading contributors to newborn morbidity and mortality, especially in low-resource settings.



The BEMPU TempWatch is a wearable temperature-monitoring wristband that continuously monitors a neonate’s temperature for 1 full month in the clinic and home. If a neonate becomes hypothermic, the device emits intuitive audiovisual alarm to alert parent so they can perform thermal care known as Kangaroo Mother Care to warm the baby. Immediate action prevents deadly consequences.

Mission and Vision

BEMPU Health’s mission is to radically improve health outcomes for children by delivering life-saving technology interventions.

Competitive Advantage

The TempWatch is the first hypothermia alert device designed for low-resource community settings. Other methods for detecting hypothermia are not continuous or do not have have an alarm capability, meaning that hypothermia may be detected too late, with dire consequences.

Planned Goals and Milestones

We are working to enter new markets across the globe to increase access to the device.
