Open Bionics Hero Arm FAQ

If you are wondering if the Open Bionics Hero Arm is the right prosthesis for you, please see some of the frequently asked questions that might help you make the decision. If you can’t find the answer you need, please get in touch with our team here.

How does a myoelectric prosthetic arm work?

A bionic arm or myoelectric arm, is a prosthesis powered by electric sensors fitted inside a prosthesis that can read muscle movements when the prosthesis is worn. These sensors read muscle movements, and depending on how you move them they get converted into intuitive bionic movements of your prosthesis. Bionic arms allow individuals to have more hand movements, with the Hero Arm you can make use of up to eight different grip modes.

Why are prosthetics so expensive?

While the Hero Arm is three times cheaper than the average myoelectric arm, costs can still put a strain on the family. Here at Open Bionics it’s our mission to make bionic arms accessible to individuals with limb differences around the world. If you need support to fund for a Hero Arm, register your interest and we will put you in touch with our customer success manager to ensure you have the support you need to fund for a Hero Arm.

What is a 3d printed hand?

Here at Open Bionics, we use clinically approved 3D printing methods to ensure your prosthesis has the perfect fit for ultimate comfort, is lightweight so you can wear it all day, and is affordable so more people can access bionic technology around the world.

Getting a Hero Arm

The Hero Arm is only available privately at the moment. We’ve been working closely with the NHS, as we’re really keen to enable our customers to get Hero arms for free through the NHS and we’re preparing for a second trial of the Hero arm. The NHS has a lot to consider when looking at new devices and decisions can take a long time but they are being very supportive towards our work. Please do mention to your NHS prosthetist that you are interested, however if you would like one immediately we would have to refer you to one of our private partner clinics.

How does the Hero Arm work?

The Hero Arm is a myoelectric prostheses. When a user intentionally flexes specific muscles in their residual limb, EMG electrodes within the Hero Arm detect tiny electrical signals, allowing them to activate different grips with precise, proportional control.

Can the Hero Arm be used by people with limb differences which are above-elbow or have a partial hand, e.g fingers and thumb?

Currently we can only fit the Hero Arm to people with below-elbow amputations or limb differences. We can sometimes help those with partial hands but please be aware that the residual limb would have to fit within a socket comfortably so it may not be suitable for all. In order to find out if you are eligible please speak to us and your prosthetist.

Research and Development

Can you make a prosthetic leg for my dog/cat?

No, we’re investing all of our energy into developing bionic limbs for humans.

Can you make me a prosthetic leg, exoskeleton, partial hand?

No, we are currently working really hard to solve problems for below-elbow amputees. We are researching and developing more assistive devices so please watch this space, but for now we are focused on below-elbow prosthetics.

Can I make a hand/be a developer?

Due to the high level of regulatory requirements and quality necessary to manufacture a compliant medical device, particularly one as complex as the Hero Arm, we are unable to sanction the manufacture of Hero Arms outside of our regulated production facility. Our focus is to improve the efficiency and quality of our production facility so I’m afraid we aren’t going to be looking to work with anyone else to manufacture our products.

Can you 3D print me a…. ?

Our printers are busy making Hero Arms! Try shapeways or 3DHubs.
