Young innovators are discovering interesting ways to power wearable devices. This latest invention, AMPY, is a winner of Proto Labs Cool Idea! Award. Not only can it give your smart wearable tech a power boost when batteries run low, it can help promote a healthy exercise program.

AMPY is a wearable kinetic device that discreetly captures your daily physical activity and converts it into charging power for devices such as smartphones, smart watches, fitness trackers, and so on.

“Wearable devices are playing an increasingly important role in daily life,” said Proto Labs founder, Larry Lukis. “AMPY embodies the spirit of the wearable segment with its effortless user integration, but simultaneously offers an environmentally friendly kinetic alternative to wall chargers.”

The compact device can be strapped to a person’s arm, leg or hip, or carried inside a backpack or messenger’s bag where it charges anytime it detects movement. A user can then plug their smartphone into AMPY to restore the phone’s battery life. “A typical day of walking — about 8,000 to 10,000 steps — gives you another three hours of smartphone battery life, and if you add another 30-minute workout that day, you’d get around 6 additional hours,” said Tejas Shastry, CEO of the Chicago-based startup. Hence, it’s an incentive to exercise.

At the heart of the device is its linear inductor. “We developed all of the proprietary architecture for the internal conductor inside AMPY,” said the company’s technical head, Mike Geier. “It’s an area that we had to invest significant prototyping hours towards and equipment to create. The result is a product unique to the wearable space.”

Shastry, Geier and fellow co-founder, Alex Smith, are all Ph.D candidates in engineering at Northwestern University in Evanston. Through the help of two accelerator programs along with their recent Proto Labs service grant, they’ve begun testing the device within an initial demographic of young, active urbanites, and have launched a crowd-funding campaign on Kickstarter.

The Cool Idea! Award provided the team with the tooling and subsequent low-volume injection molded production run for the plastic AMPY clip and housings. The parts will be used in devices shipped for pilot testing as well as upper-level crowd-funding perks for contributors. Shastry said they hope to follow the campaign with an early 2015 full-market release online.

Since 2011, the Cool Idea! Award has provided more than $750,000 in Proto Labs prototyping and short-run production services to entrepreneurs developing new products in the United States and Europe. Unlike other product 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.
