Thermometer Redesign

increased accuracy for a happy and healthy life.

Temporal thermometers are well known for their ease of use, especially with infants and todlers. Despite being popular, many lack the accuracy required for infants. How can redesigning the temporaln thermometer for brAun produce an accurate, easy to use device?




The primary user of temporal thermometers were young mothers in their early 30’s. These mothers have family sizes 3-4 people (including children). The child’s ages range from 0-10 years old.

The mother’s main goal is to quickly and accurately get the child’s temperature whether that be when the child is sleeping or awake.


Little instruction provided with the device makes it difficult to use.

Need to be as accurate as possible for infants that are more at risk than adults.

Utilizing family members over the holidays, several children ranging from the ages of 3 to 10 years old were used to imitate a child getting their temperature measured. Several adults were roped into the test acting as the mother checking the temperature.

The users were uncertain of how to hold the device properly when taking temperature measurements. They were also unsure of whether to press or hold the "head" button while taking temperature measurements leading to inaccurate readings. The mothers taking the temperatures found it hard to maintain contact with the skin.
