Prosthetic hand users need devices that work reliably throughout the day without breaking the bank. Alt-Bionics set out to build exactly that, using the open-source Brunel Hand design as their foundation. Our compact linear actuators provided the solution they needed, balancing the performance, durability, and affordability their project required.
The Challenge
Alt-Bionics needed compact linear actuators that could replicate the biomimetic movement of tendons while delivering consistent performance under daily use. Size was critical—the actuators had to fit within the constrained space of a prosthetic hand. So was reliability. Users depend on their devices throughout the day, and frequent failures weren't acceptable.
The alternatives all had problems. Some were too large to integrate effectively. Others came with price tags that would push the final product beyond reach for many users. Still others lacked the durability needed for prosthetic applications, where actuators face continuous cyclic loading and varied environmental conditions.
Linear actuation closely mimics the pull of natural tendons, making it the biomimetic choice for replicating finger movement. Alt-Bionics needed components that could balance performance, cost, and longevity without compromise.
The Collaborative Solution
We provided both the product and the partnership Alt-Bionics needed. Ryan, CEO of Alt-Bionics, put it this way: "Actuonix was kind and demonstrated a willingness to support us early on. You are also the only compact, quality linear actuator company that we know of — even to this day."
But it went beyond a typical vendor relationship. When Alt-Bionics identified performance issues under prosthetic loads, we worked together to diagnose the root causes and implement solutions. We conducted manufacturer audits that improved our process control and quality assurance, producing more robust actuators that increased device load capacity and longevity for Alt-Bionics' prosthetic hand.

Innovation in Action
Our actuators delivered where previous options had failed. The compact form factor allowed integration without compromising hand aesthetics or function. The balance of speed and force enabled responsive grip control across different tasks—from delicate object manipulation to stronger grasping actions.
Lower costs helped keep the final device affordable for more users. Short lead times meant Alt-Bionics could rapidly iterate during development and quickly replace components when needed. For users, this meant devices that respond naturally and maintain higher uptime in daily activities.
