Solico Engineers Game-Changing Comfort And Flexibility In New Axiles Bionics Ankle Prosthesis

OOSTERHOUT, The Netherlands — October 11, 2022 — Solico, a composite engineering specialist for the Industrial, Marine and Defence sectors, is delighted to announce its recent collaboration with innovative prosthetics specialists Axiles Bionics. The Axiles Bionics’ Lunaris is a revolutionary ankle-foot prosthesis which features bespoke composite components engineered and optimised by Solico.

The new Lunaris prosthesis uses advanced composite components to reduce the overall weight and outer dimensions of the unit, significantly enhancing the performance and aesthetics when compared to earlier all-metallic designs. These now allow Axiles Bionics to contain the Lunaris’ groundbreaking AI sensor package in a compact size 36 foot, as well as delivering the specific non-linear stiffness required for a more natural gait.

Solico engineers worked closely with the Axiles Bionics design and engineering teams throughout the 2 year project, carrying out laminate optimization, finite element (FE) simulations and strength verifications for the new composite components.

Katleen Mattheus, Composite Lead Engineer, Solico, said, “The Lunaris was a unique and challenging design project, being our first composite medical prosthesis design, and also a much smaller structure than we typically analyse. Our FE analysis allowed us to predict the stiffness of various set-ups and model how the foot would behave, speeding up the optimisation process and reducing the real life test time required. The final design was load tested in our lab to verify the strength and real-life characteristics of the composite parts.”

“We decided to bring Solico in since the start of our development process. Doing so very early on, and designing collaboratively has given us the opportunity to, not only, integrate high level expertise in composite materials and their behaviours, but also to bring very practical know-how in the daily and long term use of those components. This resulted in a fantastic product, as well as a significant increase in

Intellectual Property that will provide Axiles Bionics with long term competitive advantages,” said Pierre Cherelle, CEO Axiles Bionics.
