Technical springs play a vital role in industries like automotive, aerospace, and medical devices, ensuring energy storage, shock absorption, and stability. Recent advancements in materials, such as smart polymers and metal foam, are revolutionizing their performance.

Smart Polymers
Smart polymers change shape or stiffness in response to stimuli like temperature or pH. These materials improve damping, reduce stiffness-to-weight ratios, and enhance energy absorption in technical springs. However, they can be costly and may have limitations in extreme environments.

Metal Foam
Metal foam, with its lightweight structure and high strength-to-weight ratio, is excellent for energy absorption and weight reduction. It enhances spring durability and efficiency but remains expensive and complex to manufacture.

Combining Smart Polymers & Metal Foam
Using metal foam as a core with a smart polymer coating creates lightweight, high-performance springs. Applications in automotive suspension, medical devices, and aerospace benefit from improved efficiency, reduced weight, and better shock absorption.

Despite challenges in cost and processing, ongoing research continues to refine these materials, paving the way for more advanced and efficient technical springs.
