For my technology, I collaborated with Simtech. The people who helped me were Duane Lye and Wei Liang. Above are pictures of the first draft. The piezo diffuser is a small device that vibrates water into a mist. The scent comes from majority water and a very small amount of the oil. The whole set up is powered by the powerbank.

Here are the individual parts to my technology. The first picture is the piezo diffuser connected to the water reservoir, second, is the ECG device in a form of a waist band, and the third is where all the rest of the technology is. Below it is a powerbank.

Testing out the set up.
