Engineered especially for you

Each Hero Arm is unique, just like you. We take a 3D scan of your limb, use some clever software and design, and laser sinter your Hero Arm using tough Nylon 12. The full prosthesis is robust, and the innovative socket is comfortable, adjustable and breathable too, which means it’s easy to take on and off while providing you with the best possible fit.

Intuitive and effortless

With the Hero Arm, technology is at your fingertips. Literally. Special sensors within the Hero Arm detect muscle movements, meaning you can effortlessly control your bionic hand with intuitive life-like precision. Also, haptic vibrations, beepers, buttons and lights provide you with intuitive notifications.

Lightweight, powerful, strong

Even though the Hero Arm is powered by space grade motors, advanced software and long-lasting batteries, it is lightweight and super sleek. The hand, which comes in three sizes, is the lightest on the market. The Hero Arm feels like part of you. And it’s strong too, able to lift up to 8 kg (17.64 lbs).
