For the senior design projects of both of my majors (Mechanical Engineering and Industrial Engineering at Istanbul Technical University), I involved in a wearable yarn-heated garments (e-textile) project. A Textile Engineering PhD and a Mechanical Engineering PhD were together leading the project at the time.
The goal was to see if this e-textile technology would or would not be able to better carry out the legacy technology (heated metal panels) used in heated jackets in the market.
For my Mechanical Engineering design project, my contribution to this project was in determining the yarn that is the most suitable for yarn-heated jackets. Primary points of concerns were maximum warmth achieved, heating time and battery life.
Inside the lab with a friend, we tested a total of 112 polyamide and polyester conductive yarns, and revealed the optimal sample yarn. We received trainings for using Fluke thermal cameras and then conducted the processes with an Arduino system.

For my Industrial Engineering design project, my contribution was in financial aspects to this. I won't share it with you because it's irrelevant and the prices are in TL.

After working as an Aerocraft Engine Design Engineer for General Electric Aviation for a few years, I decided to quit and wanted to use my experience in insulated jacket industry as well as pursue my love for the outdoors & sports full-time. So I created OutdoorCrunch, where I share my findings in different outdoor gear, particularly jackets.
