Diseases such as stroke, diabetes, and arrhythmia are prevalent and can significantly impact an individual's quality of life. Mitigating these effects often involves regular clinical visits for close monitoring of the condition. While effective, this approach can leave patients vulnerable during periods between visits when they are not under direct medical supervision. The COVID-19 pandemic has further exacerbated the challenges of obtaining immediate medical attention. Therefore, there is an increasing need for continuous monitoring solutions that enable patients to self-monitor their conditions in real-time.

Wearable and implantable devices have emerged as crucial tools in this domain, capable of collecting data continuously and providing timely feedback while seamlessly integrating into daily life. Recent advancements in these technologies have shown promising results in the management of chronic diseases, driven by the concerted efforts of research groups dedicated to this cause.

The objective of this Methods Collection is to showcase innovative methods and tools, including device development and experimental techniques, that are pivotal in this field. We aim to provide a comprehensive resource for researchers working on similar challenges. Contributions to this collection may cover a range of topics such as sensor technology, device packaging, fabrication methods, drug delivery systems, stimulation techniques, continuous signal monitoring, and network systems for clinical connectivity. Each submission should emphasize the practical demonstration of wearable or implantable approaches.

By documenting these cutting-edge methodologies, we aspire to foster collaboration and accelerate progress in the development of life-saving wearable and implantable medical devices.
