Wearable Thermoelectric Bracelet Wins Cool Idea! Award

The latest Proto Labs Cool Idea! Award winner is literally cool … and hot, too, for that matter.

This exploded view shows how Wristify comes together, including parts that were manufactured by Proto Labs.

Wristify is a thermoelectric wearable device that actively cools or heats one’s skin for comfort by sending hot or cold pulses to a patch of skin on the wrist dozens of times per minute.

Wristify’s developers, Cambridge, Mass.-based Embr Labs, call the product a “stylish bracelet” that helps keep you cool or warm, similar to what happens when you dip your toes in a cold lake on a hot, sunny day, or when you wrap your hands around a hot cup of tea on a cold night.

Sam Shames, one of the co-founders of Embr Labs, says developers are using the Cool Idea! Award manufacturing grant for various custom prototype parts from Proto Labs such as CNC-machined aluminum enclosures and Santoprene (rubber-like) bottom components.

This is how the finished product may look.

“The prototypes we have built out from Proto Labs’ manufactured parts have been the best prototypes used to date,” Shames says. “The parts have been greatly beneficial in the prototype phase and we’ve been really pleased with the general aesthetic and design, which have a sleek look and feel to them. Plus, the functionality of these parts has been great.” Read our recent press release here.
