Wristify, which is being developed by Cambridge, Mass.-based Embr Labs, is a “stylish bracelet” that cools or heats the skin, say the developers, 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.

“The market demand for wearable devices is growing,” says Proto Labs founder Larry Lukis. “Wristify fits well into this niche and should successfully ride the wearable device trend. I see Wristify taking a prominent place next to another wearable bracelet that’s utilitarian — the Fitbit.” That could happen soon. Developers say that Wristify should be on the market in the next year. Retail price has yet to be determined.

Wristify’s concept is that the thermoelectric bracelet can influence a person’s perception of how warm or cold a room feels, by sending hot or cold pulses to the wrist. This provides personalized thermal relief directly to the wearer, potentially resolving those situations in which some people think a room is too cold versus those who feel overheated.

For now, people will use the device for personal comfort, though Embr Labs developers say the ultimate aim is to reduce the energy consumption of buildings, by cooling and heating the individual, not the building.

Sam Shames, one of four 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 bottom components. “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.”

Since 2011, the Cool Idea! Award has provided more than $1 million in Proto Labs prototyping and short-run production services to entrepreneurs developing new products in the United States and Europe. Unlike other awards that recognize products after they’re in mass production and on store shelves, the Cool Idea! Award is meant to help innovative ideas come to life.
