The rising prevalence of cardiovascular diseases (CVDs) necessitates continuous monitoring for effective management, leading to increased interest in wearable technologies that integrate seamlessly with the body. Researchers are investigating various aspects of wearable tech, including materials, design, and bioelectronics, to improve CVD detection. Key challenges remain in material selection, focusing on biocompatibility, conductivity, sensitivity, accuracy, and flexibility. This review highlights advancements in novel materials for wearable CVD detection, discussing diverse sensing mechanisms such as piezoelectric, piezoresistive, capacitive, and triboelectric modalities. It also provides an overview of current efforts in developing pulse wave sensors, heart sound sensors, ultrasound sensors, wearable ECG electrodes, and electro-biochemical sensors. The analysis aims to enhance understanding of these technologies' applications, limitations, and performance within wearable health monitoring systems for CVD.
