Inspiration

We generate so much energy that we don't use through thermal skin exchange with the air, but our idea was to harness this energy to create a method for passive energy generation integrated with clothing.

What it do

Generates power using thermal waste energy with the potential to power numerous wearable technologies.

How we built it

  1. We got peltier plate variety of different articles of clothing.
  2. We measured the voltages produced base on different temperature gradients of a single peltier plate.
  3. Based on the information collected from the previous step, the chips were wired in series to meet the required voltage. 4.We designed a housing for the peltier plates which including a complex heat dispersion system to maximize generation efficiency. 5.We then attempted to make a circuit designed to utilize the low amounts of energy generated, but unfortunately our circuitry was not efficient enough. 6.We then experimented with capacitors to store the generated electricity in usable amounts.
  4. Using 9.4F capacitors, we were able to boost enough amperage to generate enough electricity to power the boost converter, which in turn powered the LiPo charger. This allows us to charge any 1s lipo or the equivalent supercapacitor at a trickle charge.

Challenges we ran into

1.Peltier chips are inefficient at generating electricity. 2.Joule thief didn't work. 3.Not very high temperature differentiation. 4.Low current. 5.Fatigue. 6.Sickness.
7.We accidentally oxidized our copper.

Accomplishments that we're proud of

We are proud of how it looks, the concept and how much we have learned about electronics. This was a very ambitious project, and we learned a lot about storing alternative energy. Most of all we are proud that we were able to create a usable amount of energy jut off our body heat, which opens up many routes that this technology could go along.

What we learned

We learned how joule thieves worked, a fair amount more about capacitors and pullup resistors.

What's next for Power Gauntlet

  1. Make it safer
  2. Add copper fabric heat sync.
  3. Looking at fabric options that will make the device more comfortable, and more wearable. There are piezo fabrics, and we made heat sink with copper fabric, we'd like to test its efficiency.
  4. improve efficiency. little things made big changes, with more time, there are many more to update.
  5. Understanding optimum temperature situation, where this device could be useful, like physical activity in cold environments.
  6. Learn more about the efficiency of ceramic electronics co/polymers.
  7. Making a better booster circuit maximized for trickle charge efficiency, allowing long, complete, charges.
  8. Integrating a use for the energy, such as micro-controllers that track your heart rate, interactive LED gesture based safety signals for cyclists and joggers, heating elements, phone chargers, or any number of other technologies that could befit from passive charging.
