Problem

Lower-limb amputees often face challenges with existing prosthetic devices that lack the functionality to replicate natural joint movement and muscle control, hindering their ability to perform everyday activities like walking, stair climbing, and standing with stability. Traditional prosthetics can be energy-intensive and may not provide sufficient support for varied terrains or dynamic movements.

Solution

BionicM's Bio Leg® is a powered microprocessor knee designed to emulate natural muscle movement, providing below-knee amputees with enhanced mobility and stability. The device uses advanced robotics and sensors to adapt to different walking speeds, terrains, and activities, allowing for a more fluid and energy-efficient gait. By actively assisting with knee flexion and extension, the Bio Leg® reduces strain on the user's body and enables a wider range of motion, promoting greater independence and confidence.

Target Audience

The primary target audience includes individuals with below-knee amputations seeking advanced prosthetic solutions to improve their mobility, stability, and overall quality of life.
