Four students built this smart thermometer

Collin Hill learned the importance of monitoring his fever first-hand when he was diagnosed with Hodgkin's Lymphoma before he could start college at the University of Pennsylvania. During his chemotherapy, Hill had to constantly take his temperature.

One night he went to bed after measuring a normal temperature only to wake up a few hours with a high fever that took him to the ER. When sharing his experiences at a medical health conference at Penn, Hill and fellow students realised there was a solution to this problem.

Now, 18 months later, Hill William Duckworth, Aaron Goldstein and his sister Becca Goldstein are getting ready to launch Fever Smart, a device that constantly monitors someone's temperature and sends alerts to an app if a fever spikes.

With Fever Smart parents would be able to monitor their children's health at all times of the day, wherever they are. They just need to place the device - it's about the size of two quarters - under their child's armpit and secure it with a patch. It sends the data to a nearby device (including tablets and smartphones) via Bluetooth.

The information is then uploaded to the cloud so parents can stay informed even if they are not within a close enough Bluetooth range. They plan to launch an Indiegogo campaign next month to raise funds for manufacturing the devices. They're looking at a $129 (Rs 7,797) price point.

While none of them has a medical background, the father of the Goldsteins, who happens to be a physician, has been advising them through the process.
