I was able to cool the metal plate with control of how much power goes into it. In addition to that adapter plate was designed and 3D printed to attach the heat sink to the metal plate.

Stay Cool,
Perform Better.
Gain the Edge Over Your Competitors
In sports, every advantage counts. This innovative cooling device helps athletes push their limits while reducing fatigue. Whether training for a competition, coaching a school team or managing a gym, the technology regulates body temperature to boost endurance.
Try it and Get the edge to outwork the competition. Stay cooler, go further, and perform at your best.
Vision for the device ?
My vision is to explore new technology in the world of physical training whether it be for athletes, gym users, rock climbers, or workplaces, and hope to shine a light on this technology so it becomes more mainstream.
how does the device work ?
This device cools the palm by absorbing heat through a metal plate in contact with the hand and dissipating it, ensuring continuous cooling.
End Goal
I aim to build this device and test it and if it works I want to use it for myself and hopefully help my friends who play professional sports in their journey.
I was able to cool the metal plate with control of how much power goes into it. In addition to that adapter plate was designed and 3D printed to attach the heat sink to the metal plate.
I was able to create close loop system with active feedback system where the temperature of the metal plate was kept at 12 degrees.
I was able to design PCB in KiCad and than ordered it from JLCPCB, This board has two controllers and 4 temperature sensors and it is shield for Arduino Uno but complete testing is still yet to be done.
Cutting aluminum extrusions, tapping holes, assembling them, and testing the rigidity and aesthetic.
