Inspiration

Two weeks ago, an uncle of mine died with a heart attack. A heart attack is one of those ailments where the speed one gets medical care impacts your likelihood of survival.

A heart attack is also crippling. Much of the time, a victim doesn’t have time to call 911. This means that if they are alone, they are likely to die. Survival depends on someone stumbling upon them.

It could be as simple as my grandpa reading in his office downstairs and my grandmother not checking on him for hours. It could be as simple as them having nobody regularly with them as they live alone, as about 30% of seniors do.

SecureShirt is meant to give those people a chance. It’s meant to let the elderly live independent lives and still have a good chance of survival. Its meant to let their children avoid uprooting their lives to ensure that their parents do not perish.

This technology could easily be expanded with different sensor sets. Seizures, drug overdoses, solo hiking accidents, and other medical incidents which can occur when someone is alone such as allergies.

What it does

It is a shirt which monitors various physical signs to determine how healthy you are at any given point and whether you may be experiencing a serious medical condition.

How we built it

Hardware Components: DHT11 to detect the temperature and humidity MH-RD to detect sweat GY-21P to detect the barometric pressure and allow for a precise calculation. Heart rate sensor to detect pulse and blood flow An Arduino Uno to serve as the central hub of the information.

The intermediate part is built using the Arduino and Java Serial libraries to read data from serial COM port onto the computer. The computer then sends this data to the website. The double login protocols of Eduroam and GTvisitor made this intermediate step necessary.

The online part consists of PHP code and a MySQL database. A POST url is used to transfer the data between the Arduino Uno and the website and upload it to the database. The latest data is repeatedly read from the database.

Challenges we ran into

We encountered a number of challenges, one of which was that Matt needed the aid of something similar to the shirt towards the end of the challenge. Matt had an allergic reaction during the competition and spent half the night at Emory hospital.

We also spent a great deal of time trying to connect the unit directly to the internet. Our ability to do this was substantially limited by the presence of login requirements for both available Wi-Fi networks.
