BEMPU is a temperature monitoring wristband for newborn babies. The wristband intuitively alerts a parent if the baby’s temperature drops and the baby becomes hypothermic. Compared to current standards of care, the device reliably prevents hypothermia and its complications, and it promotes kangaroo mother care (skin-to-skin care) in low-resource clinics and homes. Once an infant starts becoming hypothermic, the body conserves heat by restricting the blood flow to the arms and legs. This causes the limbs to become significantly colder which BEMPU uses as an early detection sign of hypothermia. The intuitive device alerts the mother so she can swaddle the baby or perform kangaroo care, which in itself would prevent further hypothermia. Multiple alarms signal that the infant is unable to stay warm. This is significant information as it can imply a possible underlying infection and the mother can alert a nurse if in a clinic, or seek skilled care if at home in time.
