As a manufacturer of electric micro linear actuators, one of the industries that we're most excited to be directly involved with is the production of prosthetics. In recent years, we have had the privilege of working with several companies that manufacture prosthetics. This involvement has ranged from recommending the best linear actuator to meet the needs of the client, through to fully custom solutions designed to integrate seamlessly into their product.
Prosthetic technology is rapidly evolving, and the cost of that technology continues to drop. It's possible that in ten or twenty years, every amputee on earth could have access to a prosthetic limb. This would have a huge impact on quality of life for millions of people worldwide.
How Have Prosthetics Improved in Recent Years?
Materials
The cost of materials has dropped in recent years. 3D printing allows manufacturers to design and produce parts in small quantities for a low cost. Engineers, students and hobbyists can now afford to try their hand at designing prosthetic devices.
Functionality
The latest prosthetic hands have some advanced features that allow the user to really take full control of the limb. Some of the features that are coming available in prosthetic hands for example are pivoting opposable thumbs, rotating wrists as well as temperature and force sensing capabilities.
Cost
3D printing is fairly inexpensive, and printers are now available at colleges, universities and even some public libraries. The availability of inexpensive micro linear actuators also reduce costs considerably. A prosthetic hand might have as many as 6 actuators so this is a cost that can add up. All of our most popular miniature actuators for prosthetics are less than $100USD. Bulk pricing is also offered allowing manufacturers to save more money.
Superior to a Human Hand?
Prosthetic hands have evolved to the point where they are in some regards, superior to biological hands. New-age prosthetics have outstanding grip strength and some offer wrist-rotation that is well outside the human range of motion.

Here are a Couple of Companies on the Cutting Edge of Prosthetic Hand Design
Alt-Bionics
Alt-Bionics has taken affordable prosthetic hands to new levels with unique features including visual force feedback and a multifunction button. They feature modular fingers with replaceable fingertips. Alt-Bionics has created something truly unique and we're excited to see where the company goes from here.
Open Bionics
Open Bionics was founded by Joel Gibbard and Samantha Payne in 2014. Their first product, the ADA hand is a 3D printable, open-source prosthetic hand. In recent years, they have developed a prosthetic arm, dubbed the "Hero Arm" which is available for both adults and children.
What's Next for Prosthetic Technology?
Today's low-cost prosthetic hands are far more advanced than anyone could have predicted 20 years ago. We’re excited to see what the future holds for this industry. With innovative companies like those mentioned above leading the way, there’s a lot to look forward to.
Common Questions About Prosthetics and Linear Actuators
How can linear actuators be used in prosthetics?
Linear actuators are used to control various movements in prosthetic limbs, such as finger articulation and wrist rotation. They provide precise control and enable prosthetics to mimic natural movements more closely.
What is the best actuator model for prosthetics?
Our PQ12 model has been incredibly popular with prosthetic hand designers. That said, it really depends. The actuator or servo you choose will depend on your design requirements. Physical space, control type, voltage, required force and other factors will all play a role in determining which is the right solution for your prosthetic design.
How do I choose the right actuator for a prosthetic limb?
Selecting the right actuator depends on factors such as the required force, speed, and size. Our Actuator Selector Tool can help you find the best option for your needs. For more detailed advice, feel free to contact us.
Can you build me a custom prosthetic actuator?
Yes, we can. We pride ourselves on our ability to customize actuators from a custom end tip or cable through to a completely custom design from the ground up. For custom products, there is a minimum order quantity starting at 500 units.
