Harnessing energy for wearable technology: a sustainable approach

Abstract

Recent advancements in electrical sensing and electronics have notably propelled the progress of wearable fitness and medical technology. Key to these applications is the mobility of wearable nodes, essential for remote patient monitoring. However, the limited lifespan of wearable devices, particularly in biomedical applications, poses a significant challenge to their widespread adoption. Energy harvesting technology emerges as a promising solution to this issue, despite the inherent challenges of size, weight, and cost restrictions for wearable devices. This study presents three innovative strategies for harnessing solar and thermal energy at wearable sensor nodes, offering new pathways to overcome the longevity constraints of wearable technology.
