THE PROBLEM

Global Accessibility Crisis

Millions of amputees worldwide face prohibitive costs and limited access to functional prosthetics. Traditional bionic arms remain a luxury, creating a massive healthcare disparity.

40M+

Amputees Worldwide

Due to diabetes, trauma, conflict injuries, and accidents, prosthetic limb market is crossing multibillion-dollar mark. Growing populations in developing nations face significant barriers to healthcare access.

$10K-$50K

Prosthetic Arm Cost

Existing solutions are either low-cost with minimal functionality or advanced but extremely expensive and complex. Most users abandon devices due to imperfect control and high maintenance costs.

5-10%

Access in Developing Countries

In developing countries, no more than 5-10% of amputees gain access to effective solutions. High costs and limited availability create significant barriers to adoption.

THE SOLUTION

Revolutionary Approach

Democratizing bionic technology through smart engineering, AI-driven signal processing, and innovative cost-reduction strategies.

AI-Powered Signal Processing

Combining EMG and SMG (muscle sound imaging) sensors for robust intent recognition. Machine learning decodes multimodal bio-signals for instinctive prosthetic interactions.

Energy-Efficient Design

Spring-lock mechanism enables zero-energy static grip, extending battery life. Power consumption analysis shows up to 90% reduction compared to traditional designs.

Adaptive Software Control

Layer-based system provides individual practical experience. Software-centric design reduces mechanical complexity and maintenance costs significantly.

Minimalist & Affordable

Priced between $850-$1,000 instead of $10,000-$50,000. Cost-effective yet strong materials ensure durability without compromising lifespan.

Our Story

Driven by Compassion and Innovation

The group was formed as a result of team leader's passion to solve the suffering of his friend. Team leader Washiun Alim took a close look at struggles faced by his friend, "Salman Ahmed," both mentally and physically, after his upper limb was amputated. This direct human experience triggered him to investigate the global shortage of prosthetics that can actually restore people's emotions after limb loss.

OUR IMPACT

Transforming Lives

Technology transforms prosthetics into adaptable, responsive extensions of human body rather than passive mechanical tools.

Individual Impact

Ensures mental well-being, physical ability, and confidence. Patient trials confirmed grip, strength, and usability are suitable for everyday interactions. Users can earn and do their jobs.

Millions

Potential to transform millions of patients with upper limb amputation worldwide through affordable technology.

Societal Impact

Increases reach of functional prosthetics to millions of upper limb amputation patients. Potential to boost labor market participation, decrease healthcare costs, and enhance social integration.

Global

B2B2C model through hospitals, rehabilitation centers, NGOs, and government programs.

Market Potential

Prosthetic limb market worth several billions of dollars worldwide and still expanding. Great chance for widespread adoption with a low-cost system.
