Biosensors for the IoT: Principles, Potentials, and Applications

Biosensors for the Internet of Things (IoT) represent a transformative integration of biological sensing with digital communication over the Internet, enabling real-time monitoring of health, environment, and industrial processes. These devices convert biological responses into electrical signals, which are then transmitted via IoT networks for analysis and decision-making. Applications range from wearable health monitors to smart agriculture systems that track soil conditions and plant health. When combined with IoT, biosensors offer enhanced data collection, remote monitoring, and automation. The rapid advancements in nanotechnology, wireless communication, and data analytics are further enhancing the sensitivity, miniaturization, and efficiency of these systems. As a result, biosensors for IoT hold immense potential to transform healthcare, environmental monitoring, and industrial automation by providing timely, accurate, and actionable insights across various sectors.
