What Sets TrueLimb Apart from Other Bionic Arms

TrueLimb is a complete arm prosthetic solution designed to feel like a natural extension of the body rather than a mechanical device. Each arm is customized to match the user’s opposite limb, including fingertip size and skin tone. Various color options are available, ranging from natural tones to jet black and metallic silver.

Instead of using standard sizes, TrueLimb is individually tailored using a remote 3D scanning system. This digital process eliminates the need for in-person fittings and allows for precise, personalized design. The socket is breathable, adjustable, and suitable for all-day wear. With a built-in BOA dial, users can easily adjust the fit. Weighing just 1.0 to 1.5 pounds from socket to fingertip, the prosthetic remains lightweight and comfortable.

Intuitive Control Powered by Smart Sensors

TrueLimb features TrueSense technology, which incorporates over 30 topographical sensors embedded within the socket. These sensors detect subtle muscle movements on the residual limb, providing precise and responsive control, even when the limb is covered or sweating.

While often described as “mind-controlled,” TrueLimb does not directly read brain signals. Instead, it utilizes advanced sensors to interpret electrical activity from muscles in the residual limb. These signals mirror the user’s intended movements, enabling the prosthetic to respond instantly, creating a seamless, intuitive experience that feels natural.

WHAT IS ARTIFICIAL INTELLIGENCE (AI)?

The system adapts automatically by identifying the most active myo sites, deactivating less useful sensors, and adjusting responsiveness based on the user’s signal strength. This ensures consistent performance, even if muscle activity changes over time.

The prosthetic offers six intuitive grip patterns to support various daily activities. Independent finger joints allow the hand to wrap around objects naturally, providing both strength and flexibility. The device is precise enough to handle delicate tasks, such as lifting an egg without breaking it.

Experience Touch with Haptic Feedback Technology

In addition to movement, TrueLimb restores the sense of touch to the user. Gentle vibrations provide feedback when the prosthetic hand makes contact with objects, enabling users to operate the device without constant visual attention, making actions more fluid and natural. The thumb is opposable, giving users better control over grip force and object manipulation, whether opening a bottle or holding a pen.

Durable and Lightweight for Daily Use

Constructed from PA12 nylon, a highly resilient material used in industrial applications, TrueLimb is built to withstand everyday challenges. It is splash-resistant, heat-resistant, stain-resistant, and durable enough to endure impact or abrasion. With a rubberized palm and coated fingertips, the hand maintains a secure grip on smooth or slippery surfaces. Equipped with bionic strength, it can effortlessly lift objects weighing up to 15 pounds.

Fast Charging and Long Battery Life

Keep moving without worrying about power limitations. TrueLimb utilizes a USB-C charger, the same type used for most phones and laptops, eliminating the need for a special adapter. The high-capacity 5600mAh battery provides multi-day usage, allowing freedom of movement without frequent recharges. The device also receives over-the-air software updates, enhancing performance over time without requiring a device return. Behind the scenes, analytics tools optimize each arm’s performance based on usage.

Design and Delivery from the Comfort of Home

A remarkable aspect of the TrueLimb process is its remote delivery system. Everything is handled from a distance. Users receive a 3D scanner by mail to capture their limb’s shape. The data is sent directly to the Unlimited Tomorrow team, who fabricate the prosthetic in-house. This approach eliminates intermediaries and significantly accelerates delivery. Users typically receive their customized prosthetic within a few weeks.

With TrueLimb, you receive a high-tech, personalized solution faster and at a lower cost. You regain full control and comfort, as the sensors respond to your muscle signals instantly. The arm fits seamlessly, looks natural, and feels like a part of you.
