Problem being addressed

Hypothermia is a leading cause of infant death in developing countries. Thermometers can be expensive and some require electricity or batteries, which can be a difficult burden on the user. There is currently no low-cost method for continuous monitoring of an infant's body temperature.

Detailed description of the solution

Thermospot is a low-cost, reusable hypothermia indicator designed particularly for use by illiterate mothers. It is a small, flexible sticker with a smiley face to be applied to the infant or child's skin. The LCD screen on the disc changes color in accordance with the infant's core temperature. It is green with a smiley face when core temperature is between normal limits, and the smiley face disappears and the disc turns black to indicate severe hypothermia.

Designed by

  • Designed by: John Zeal in the mid-1990s (original design)
  • Manufacturing: worldwide. It can be purchased at

When and where it was tested/implemented

Thermo-spot has been field-tested for more than a decade in several locations including Northern India and Malawi. It is available for sale for less than 8 US cents, and the cost is expected to decrease with mass implementation. This device is now currently available for purchase.

Funding Source

Clinical studies were funded by the Bill and Melinda Gates Foundation and Save the Children. The Johns Hopkins School of Public Health has also contributed to this product's development.
