THE EVOARM SYSTEM
Engineered for Mobility. Built for Life.
Explore the modular, high-fidelity 3D-printed prosthetic system designed to bridge the gap where insurance ends.
A MASTERCLASS IN MODULAR ASSEMBLY
WebView I Version 2 elevates every detail of the EvoArm platform with precision engineering and user-first design.
JH A-Settings Finish
A pristine white medical-grade finish that communicates confidence and clinical precision at first glance.
The “Click” Logic
Optimized tolerances ensure every component clicks into place — not snaps. Assembly feels intuitive, not forceful.
Single-Cable Return
The cable is housed entirely within the hand — one closing cable delivers clean, reliable actuation with zero external routing.
THE 5-PART SPECIFICATION SYSTEM
Five precision-engineered modules combine into one cohesive prosthetic system.
Modular Finger System
Repeating index-to-pinky architecture allows each finger to be individually replaced, reducing repair time and cost.
Oppositional Thumb System
Dual-axis movement enables complex grip patterns, from precision pinch to full opposition for everyday tasks.
Structural Palm Chassis
The core structural frame integrates EMG sensor nodes and serves as the central cable-routing hub for the entire system.
Rotational Wrist Connector
A modular interface joint that enables smooth pronation and supination rotation, connecting the hand to the forearm sleeve.
Anthropomorphic Forearm & Bicep Sleeve
Anatomically contoured to match realistic human limb volume, providing both structural support and a natural silhouette.
INTUITIVE BIO-FEEDBACK
A seamless control loop between user and prosthetic, powered by embedded sensors and intelligent grip software.
Integrated EMG Nodes
Embedded within the palm chassis and socket interface, picking up electromyographic signals to translate muscle intent into grip actuation.
Custom Grip Profiles
Pre-configured and user-tuneable grip patterns tailored to daily needs — from holding a cup to turning a key.
Safety Boot-Up Sequence
Activated via the center blue button, the boot-up sequence calibrates sensors, confirms connectivity, and verifies safe operating range before use.
THE JH MASTER TIP: BETTER BY DESIGN
Every component is designed for longevity, repairability, and forward compatibility.
Lower Cost of Ownership
Modular parts mean you replace only what breaks. No full-system overhauls — just targeted, affordable fixes.
User-Serviceable
Designed so the wearer or caregiver can perform routine maintenance and part swaps without specialist tools or clinic visits.
Upgradable Hardware
As the EvoArm platform evolves, new modules slot into the same chassis — future-proofing your investment in mobility.
MASTERY IN MOTION
A growing library of grip patterns engineered for real-world tasks.
Power Grip
Full finger wrap for cylindrical objects — bottles, handles, tools. Maximum contact surface area for a secure, confident hold.
Tripod Grip
Thumb, index, and middle finger converge for precision tasks — writing, picking up small objects, and fine manipulation.
Key Grip
Lateral pinch between thumb and index finger — ideal for turning keys, holding cards, and managing thin, flat objects.
