The creators of a wearable kinetic device called AMPY have been presented with the latest Proto Labs Cool Idea Award. AMPY lets users discreetly capture and convert their daily physical activity into charging power for their smartphones. The Cool Idea Award provided the team with the tooling and subsequent low-volume injection-moulded 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 crowdfunding perks for contributors. 

The compact device can be strapped to person’s arm, leg or hip, or carried inside a backpack or messenger’s bag, where it charges anytime movement is detected. 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 — provides users with another three hours of smartphone battery life, while another 30-minute workout that day would equate to around six additional hours.

The company developed all of the propietary architecture for the internal conductor — which is at the heart of the device — inside AMPY.

Proto Labs

Proto Labs delivers fully functional prototypes in production-intent materials to dramatically cut the cost and time normally associated with product development. This empowers designers and engineers with the means to rapidly develop, test, and get their products to market first in an ever-competitive global market place.

Protomold delivers injection-moulded parts from moulds manufactured utilising state-of-the-art high-speed CNC machining technologies. Parts can be moulded using almost any engineering-grade resin and are ideal for prototyping, bridge tooling and low-volume production.

First Cut satisfies the need for functional prototypes much earlier in the development cycle for quantities of 1–10+. Because First Cut delivers prototypes in engineering-grade resins and aluminium they will have real material properties and improved surface finishes. In other words, they will be functional.

When you submit your 3D CAD model, Proto Labs’ powerful super-compute cluster creates an interactive quote giving pricing options and where appropriate, suggesting changes to improve manufacturability. You simply interact with your quote online, tailor options such as material and delivery to your requirements and with every change, the pricing information automatically updates. This built-in ‘what-if’ analysis enables last-minute project refinements to be accommodated at the click of a button.
