TrueLimb is a solution for individuals with either a congenital or acquired limb difference. Unlimited Tomorrow currently works with individuals who have either a transradial or wrist disarticulation limb difference. We will be expanding our offerings in the future so be sure to follow our newsletter! Join our email list.

TrueLimb works by reading and collecting muscle data from your residual limb through sensors embedded within the socket. This data then controls a number of grips and movements. 

What makes TrueLimb different from other myoelectric devices is that TrueLimb’s socket is embedded with more sensors than required in order to ensure contact with your muscles for more successful grip activation.

TrueLimb is suitable for ages 7 and above.

Unlimited Tomorrow assesses each individual as a unique case. To find out if TrueLimb is right for you, you can get started here: Am I a candidate?

TrueLimb has a multi-day battery life.

TrueLimb is splash proof, but not waterproof. You cannot swim or shower while wearing your TrueLimb.

The device is not protected from dust or other particulates, but it is resistant to dust collection through use. It has limited ingress points, so we ask that our users be mindful of the openings in the device.

Other FAQs About Bionic Prosthetic Arms

Prosthetic arms can be made from a wide variety of materials including acrylic resin, carbon fiber, thermoplastics, silicone, aluminum, and titanium. TrueLimb devices are  made of industrial-grade PA12 nylon with acrylic and rubberized coatings. Numerous other actuators, electronics, and hardware are housed in the arm to provide proper functionality.

A bionic arm is a type of prosthetic arm. Prosthetic arms generally fall into three categories – passive, body-powered, and myoelectric. A bionic arm is considered to be in the myoelectric device category.

Some bionic arms provide what is called “haptic feedback” which means that the device will vibrate when it comes in contact with an object, providing a sense of touch.

Bionic arms range in cost and are generally $20K-$80K+. TrueLimb is the most affordable bionic arm on the market and costs just $7,995 with everything included. To learn more about pricing, visit our pricing page.

In general, bionic arm batteries last about a day, depending on usage. TrueLimb was designed to last for multiple days without needing to be recharged.

Some of the most popular bionic arms weigh in at over three pounds. The TrueLimb weighs just 1-1.5 lbs on average.

Bionic arms are controlled by sensors in the arms’ sockets. The socket functions as the way the arm connects to the body. It also contains the control mechanism for the arm. The sockets have sensors in them, and the sensors register muscle movements in your residual limb.

The sensors in traditional myoelectric prosthetic arms pick up electric signals generated by your muscles. This is where “electric” in the term “myoelectric” comes from, with “myo” meaning muscle. Typically there are two sensors in the socket, on either side of the residual limb. These myo-sites detect a muscle flex in either direction. 

These sensors need to be very precisely placed in the socket, and align perfectly with the muscle sites they are receiving electrical signals from. They also require direct contact with the skin in order to register an electric signal. If there is no direct contact with dry skin, or the sensors are not perfectly placed, control of the arm will be impacted. You can not wear a protective sock while using a myoelectric prosthetic arm. 

Instead of just two sensors, TrueLimb employs a range of 30+ sensors embedded within the socket. This 360-degree array of sensors responds to topographic changes in your residual limb, not electrical signals. Since TrueLimb is not responding to electrical signals, direct skin contact with these sensors is not necessary. If you prefer, you can wear a protective sock on your residual limb. Perspiration or moisture will also never interfere with your control of the arm.
