Problem
Existing prosthetic hands often rely on complex electronics, leading to fragility, water sensitivity, and the need for frequent charging, which limits their practicality and usability in everyday situations. Body-powered hooks offer robustness but lack the dexterity and natural grasping motion needed for many tasks.
Solution
Metacarpal designs and manufactures body-powered prosthetic hands utilizing Reactive Body Power technology, providing intuitive control and a natural grasping motion without electronics. The multi-articulated hand automatically adjusts its grasp around objects of any shape, enabling users to perform daily tasks such as cooking, cleaning, and self-care. The design prioritizes durability and water resistance, making it suitable for real-world conditions. The hand's fluid motion and variable grips enhance functionality, while its simple design minimizes the need for clinic visits and eliminates daily charging.
Target Audience
