AB  - It is crucial that clean energy is produced from even the smallest sources in order to reduce reliance on other unsustainable power sources like lithium-ion batteries. Many small devices are powered by lithium-ion batteries, despite that they can only be re-used so many times before they are defective, and the mining required to make them can cause many environmental and human rights problems. 

Consequently, we decided to produce a heart rate monitor which is powered by the user's body heat using thermoelectric generators. These generators are panels with two metal-semiconductor sides and generate energy through the transfer of electrons. There have been other products created which use this technology such as a coffee mug that produces electricity using heat from the coffee. However, our project is unique because it takes advantage of a more stable source of thermal energy, body heat, compared to coffee which will eventually cool off. The thermoelectric generators are attached to a chest strap. We decided to use the chest because this part of the body has a large surface area, so it is easier to take advantage of body heat emitted.

Our product does address the given problem, but more as a proof of concept than a marketable product. Due to limitations such as time and money, our product is quite uncomfortable. A Redboard, battery pack, breadboard, and TEGs are all attached to the chest strap. With more expensive materials, these components could be made more compact and comfortable. Our product also relies on lithium-ion batteries to assist the TEGs, which seems to counter our stated goal. However, the TEGs still add longevity to the batteries and reduce the amount of external energy that must be consumed. The LCD takes 5 volts to run, which uses the majority of energy generated. With a lower-powered LCD, and a more efficient heart rate sensor that has less power usage over time, our product could be made without reliance on lithium-ion batteries.
