A body temperature monitor designed to save the lives of half million children dying of malaria annually.

What is it?

TermoTell is a bracelet used to monitor and analyzes a child’s temperature and sweat at real time.
It is colorful, chewable and soft, designed to be easily worn by infants and toddlers under 5 years. It is low cost, washable and battery enabled.
We choose to monitor temperature and humidity based on the knowledge that Malaria patients have a unique temperature/sweat fingerprint that if properly monitored, could be used as an early diagnosis tool.

To collect data, we are using temperature and humidity sensors, and 3 LED Lights, indicating different system states (e.g low battery or danger). Bluetooth technology is used to wirelessly connect the bracelet to a feature phone. Data logger is used to store information that is helpful for diagnose and research.

Once a dangerous temperature pattern is recognized, the bracelet will glow and send an alert to a feature phone owned by a parent or other community member.
It will inform them when its crucial to seek medical attention.

TermoTell is also a data collection tool. Using internet technology, patient data is being stored, analyzed and shared among researchers around the world. Thus, researchers can identify patterns and increase of malaria cases.

How is it used?

TermoTell is worn on the child wrist. Its soft and chewable texture makes it useful for teething and for toddlers who tends to chew.
Every family will get one bracelet for each child under 5 , and one feature phone that will be placed in x range from the children.
The bracelets will send a signal to any phone within range to alert other members of the community such as teachers, in case the parent is not around.

What technologies does it incorporate?

– Sensors: Temperature and humidity sensors
– Data logger- SD card
– Data Analysts – Open source such as Python
– Alert : Bluetooth technology for communication between bracelet and feature phone
– Bluetooth or internet connection to transmit data from bracelet to smart phone (if available)
– internet connection to share data with other researchers
– CDC data base
– Battery – Lithium coin cell battery (prototype)

How does it work?

Using temperature and humidity sensors, the bracelet is designed to monitor the child’s temperature in real time.

Malaria patients have a unique temperature fingerprint, and the data collected from the child is being analyzed against that fingerprint.
The bracelet will begin to glow once it detects high fever and once it recognize a dangerous pattern of temperature (based on its unique temperature fingerprint), The bracelet will send an alert to the nearest feature phone (signal range to be defined). Then the parent (or other member of the community) can track for the glowing bracelet (in case there are more than one child under 5 ), and take the child to the nearest doctor.

Who uses it?

Children under 5 years will wear the bracelet, and parents or other community members will be holding a feature phone to where the bracelet is connected via bluetooth. Local doctors and hospitals will have access to the bracelets and information on their wearers. The data can be transmitted from the bracelet to a network of researchers around the world. Local communities can assist with distributing, assembling and maintaining the bracelets.

Why does it help?

TermoTell could answer one of the most elusive problems when facing malaria: fast and accurate diagnosis. Moreover, TermoTell also has the advantage that can be used and easily monitored by any person independently of their educational level with a very basic training.
