Prototype developed by university students in Brazil uses sensors to analyze movements, allows part replacement, and could reach SUS in up to three years
A 3D printed knee developed by Brazilian students could enhance the quality of life for amputees by offering a more accessible, customizable prosthesis that closely mimics the body’s natural movements. The prototype is still undergoing tests and could reach SUS in up to three years.
3D printed knee aims to mimic natural movements
The prosthesis is part of a collaborative research between FEI and other institutions, funded by the Financier of Studies and Projects (Finep), and recently won the Transformation in Society category of the InovaFEI award, promoted by the institution.
It uses 3D printing to produce a prosthetic knee with greater adaptability to the patient.

Satellite images show that Brazil has shrunk by more than 2.5 million hectares of rivers and lakes in 40 years, and the Pantanal, which depends almost 100% on rain due to the lack of dams, was 56% below the historical average of water in 2025.

China activates a 35.6-tesla super magnet in Beijing, surpassing Earth’s magnetic field by 700,000 times and opening a new phase in the race for semiconductors, clean energy, and extreme science.
According to Felipe Batista, in São Bernardo do Campo (SP), tests conducted so far show that the equipment can mimic the body’s natural movement more accurately.
Sensors help customize the prosthesis
The proposal includes the use of sensors to analyze each patient’s movement. With this data, the team aims to produce a personalized prosthesis, adjusted to the needs of those who need to walk again.
Another unique feature mentioned in the project is the ability to adapt and replace parts over time, which is important for growing children and adolescents.
Cost and access are central points of the project
Mechanical engineering professor Mohammad Shaterzadeh states that traditional prostheses are costly and lack flexibility. For him, replacing the entire knee is unfeasible due to the high cost.
The expectation is that the technology could reach SUS in up to three years, increasing access for patients like Heitor, a nine-year-old who dreams of becoming an amputee soccer player.
