Abstract
Triboelectric nanogenerators (TENGs) have emerged as transformative technologies in biosensing, offering unprecedented energy efficiency and precision in monitoring vital physiological signals. This review delves into the cutting‐edge advancements in TENG sensors, highlighting their exceptional potential in bioengineering applications. Key operating mechanisms and advanced materials are explored, with a focus on their impact on sensor sensitivity, durability, and biocompatibility. Cardiovascular monitoring is presented as a pivotal application, where TENG sensors demonstrate exceptional capability in detecting subtle mechanical signals such as pulse waves and heartbeats in real time. Their self‐powered nature eliminates the need for external energy sources, and their inherent scalability and adaptability make them ideal for integration into wearable or implantable devices. Benefits such as miniaturization, energy efficiency, and biocompatibility are discussed, alongside challenges like material fatigue and long‐term stability in biomedical environments. Future directions include optimizing TENG materials for enhanced mechanical robustness and expanding their integration into advanced medical diagnostics. This review provides a comprehensive roadmap for leveraging TENG technologies to revolutionize continuous cardiovascular monitoring and broader medical applications.
