Battery-Free Beacon Tag Solution for Smart Location Management

In recent years, the need to track the real-time location of people and assets has increased across a wide range of environments, including offices, hospitals, factories, and nursing care facilities. Especially in scenarios such as monitoring the elderly or children, analyzing employee movement, managing equipment and assets, or detecting entry into hazardous areas, the ability to visualize location information within a local space plays a crucial role in improving operational efficiency and ensuring safety. 
Energy harvesting technology that utilizes weak ambient energy holds the key to simultaneously solving these field needs and challenges.

AKM’s newly proposed battery-free beacon tag solution operates without any batteries or charging, combining photoelectric components and a small capacitor to enable “battery-free” operation. Through this material, we present the key features of the product, its system architecture, and the results of an in-house proof-of-concept deployment, providing concrete insights for realizing a practical and sustainable location tracking system.
