As healthcare systems around the world adapt to aging populations and expanding surgical capabilities, the materials that underpin medical devices are again drawing attention. Metal biomaterials — long used in surgical instruments, orthopedic devices, dental restorations, and cardiovascular tools — remain a staple in clinical practice. Yet questions about longevity, biological responses, and design trade-offs…

As medical science continues to move toward solutions that work in harmony with the human body, piezoelectric biomaterials are emerging as a topic of growing interest. These materials are capable of converting mechanical movement into electrical signals, opening new possibilities for healthcare technologies that rely on the body’s natural motions rather than external power supplies….
