The only concern I have is: If you perceive your body as being cooler than it actually is, aren't you running the risk of heat stroke?
The device is intended to be completely wearable, with a weight comparable to a men’s wristwatch. Wristify
powers their wristband with a lightweight lithium ion battery, similar to those used in cell phones. The device’s
energy consumption is algorithmically controlled so that it can last a full day on a single charge. While they are excited with their product, team members report there is still a lot of technological and product development needed before the Wristify team has a product ready for sale. They will soon begin working with design and development firms to improve the aesthetics and functionality of the nextgen prototype. They estimate
they are still 1-2 years away from the first publicly available product.
