- The prosthesis improves autonomy and quality of life for people with total or partial absence of the upper limb
Alicante (26/05/26).- The Joint Research Unit in Biomedical Design and Manufacturing (BioFab), made up of researchers from the Alicante Institute for Health and Biomedical Research (ISABIAL) and the University of Alicante (UA), has developed a new multifunctional and customizable upper-limb prosthesis designed for people with the absence of the arm or elbow joint.
The prosthesis, which has been validated by users, allows daily tasks to be carried out independently. Specifically, the team has opted for a modular design manufactured using 3D printing that seeks to improve autonomy and comfort at a low cost.
The device allows different accessories or gadgets to be exchanged depending on the activity to be performed, facilitating basic daily tasks such as eating, dressing, writing, or holding objects. The system also includes an adjustable telescopic structure and a customized socket adapted to each patient’s anatomy.
One of the main problems with current advanced prostheses is their high cost and technological complexity. Many models incorporate sensors, motors, or specific software that increase the price and limit user autonomy due to the need for frequent recharging.
In contrast, the solution developed by the BioFab team, in collaboration with the university association Artefactos, is based on a simple, lightweight, and functional mechanical system, without external screws and with easily interchangeable modules that do not require additional tools
“Our goal is to offer a more versatile, adaptable, and affordable prosthesis that truly facilitates everyday autonomy and prioritizes the real needs of users,” explains the scientific director of BioFab, Javier Esclapés
Among the advantages of this innovative design, the socket is made of a flexible, washable, biocompatible material that is comfortable for direct contact with the user, ensuring an ergonomic and suitable fit for prolonged use
The body of the device is printed using the material that best suits the function to be developed. For example, in the case of the module designed for autonomous cooking, it is made of a rigid, impact-resistant material with high heat tolerance to facilitate cleaning and maintain adequate hygiene measures
On the other hand, the use of 3D printing makes it possible to accelerate customization and adaptation to different users quickly, without the need for molds and with lower manufacturing costs
The new multifunctional and customizable upper-limb prosthesis is protected through a patent application. The Technology Transfer Office (OTRI) of the University of Alicante and ISABIAL’s Innovation Unit are seeking companies in the assistive products and rehabilitation sector interested in collaborating in its industrial validation and future commercial exploitation through licensing agreements
Collaborative workshops with users
Tomorrow, Wednesday, May 27 at 5:00 p.m., the final session of a collaborative workshop will take place at the 3D Laboratory of the Department of Graphic Expression, Composition and Projects of the Higher Polytechnic School of the University of Alicante. In this workshop, users, families, therapists, and engineers evaluate, test, and refine the first prototypes of the prosthesis. This initiative has been promoted by the university association Artefactos in collaboration with BioFab, ISABIAL, and COEMFE Alicante
“For us, it is essential that the user handles each component to achieve truly functional products. Thanks to this initiative, we continue to promote the design of optimal solutions that expand the possibilities of a prosthesis, such as playing the guitar, eating independently, or riding a motorcycle while taking care of posture and psychosocial health,” explains the president of Artefactos, Mercedes Llorens
