Transforming Access to Advanced Prosthetics

Once prohibitively expensive, bionic arms used to cost more than a new car, making them inaccessible to many who needed them. Today, innovative companies like Unlimited Tomorrow are changing the landscape by offering high-quality, fully customizable prosthetic limbs at a fraction of the traditional cost—under $8,000—without sacrificing comfort, durability, or functionality.

Founded in 2014 by Easton LaChappelle at just 18 years old, the company’s mission has been clear: to provide more individuals with access to sophisticated prosthetic solutions that seamlessly integrate into their daily lives. Their flagship product, TrueLimb, is already helping both adults and children worldwide regain mobility, confidence, and independence.

Personalized, Comfortable, and High-Tech

TrueLimb is designed to feel like a natural extension of the body rather than a mechanical device. Each prosthetic arm is custom-tailored to match the user’s remaining limb, including fingertip size and skin tone, with options ranging from natural shades to metallic silver and jet black. The entire fitting process is digital, utilizing remote 3D scanning technology that eliminates the need for in-person fittings and ensures a precise, personalized fit.

The socket, crafted for all-day comfort, is breathable and adjustable. A built-in BOA dial allows users to fine-tune the fit easily, ensuring maximum comfort during extended wear. Weighing only about 1.0 to 1.5 pounds from socket to fingertip, TrueLimb remains lightweight, enabling users to move effortlessly throughout the day.

Advanced Sensor Technology for Natural Control

TrueLimb incorporates TrueSense technology, embedding over 30 topographical sensors within the socket that detect subtle muscle movements in the residual limb. These sensors capture electrical signals generated by muscle activity, providing accurate and responsive control of the prosthetic—even when the user is sweating or the limb is covered. This system is often mistaken for “mind-controlled” prosthetics, but it actually responds to electrical signals from muscles, not direct brain signals.

The device employs artificial intelligence (AI) algorithms to adapt dynamically by identifying the most active muscle sites and optimizing responsiveness. This ensures consistent performance, even as muscle activity varies over time.

Functionality That Supports Daily Life

TrueLimb features six intuitive grip patterns, supporting a wide variety of everyday tasks. Independent finger joints enable a natural grasp, allowing the prosthetic to wrap around objects with both strength and finesse. It can delicately lift fragile items like eggs or firmly grip tools and bottles, making it versatile for daily activities.

Beyond movement, TrueLimb offers sensory feedback through gentle vibrations that simulate the sense of touch. This tactile response helps users operate the prosthetic more instinctively, often without needing to look at their hand. The thumb is manually opposable, providing better control over grip strength and object manipulation, whether opening a bottle or writing with a pen.

Durable, Lightweight, and User-Friendly

Constructed from PA12 nylon—known for its industrial-grade strength and durability—TrueLimb is built to withstand everyday wear and tear. It is splash-resistant, heat-resistant, stain-resistant, and tough enough to handle impacts and abrasions. Rubberized palms and coated fingertips ensure a secure grip on slippery or smooth surfaces. With bionic strength, the arm can lift objects weighing up to 15 pounds with ease.

Powering the device is a USB-C rechargeable battery with a capacity of 5600mAh, providing multi-day use without frequent recharging. The prosthetic also supports over-the-air software updates, improving performance over time without the need for returns or visits to a clinic. Behind the scenes, analytics monitor usage to optimize the arm’s responsiveness and functionality.

Fast, Remote Customization and Delivery

One of the most groundbreaking aspects of TrueLimb is its remote customization process. Users receive a 3D scanner in the mail to capture their limb’s shape at home. The data is then sent directly to the company’s in-house team, which manufactures the prosthetic without middlemen, significantly reducing wait times. Typically, users receive their personalized prosthetic within a few weeks, making this technology faster and more accessible than traditional options.

Empowering Users with Independence and Confidence

This innovative approach eliminates the lengthy procedures, insurance hurdles, and repeated fittings often associated with prosthetic acquisition. TrueLimb offers a cutting-edge, affordable, and fully customized solution that responds instantaneously to muscle signals, fitting perfectly and functioning seamlessly as part of the user’s body.

Unlimited Tomorrow’s TrueLimb is a testament to how combining 3D printing, smart sensors, and remote manufacturing can revolutionize prosthetic care. Lightweight, durable, and user-friendly, this device restores freedom and functionality to those who need it most.

Would You or Your Loved Ones Benefit?

If you or someone close to you could benefit from this technology, it might represent the next step toward greater independence. The combination of advanced features, affordability, and rapid delivery makes TrueLimb a game-changer in the field of prosthetics.
