Special Issue Information

Dear Colleagues,

Recent advancements in Internet of Things (IoT) technologies have revolutionized the way we approach sensing, data collection, and decision-making processes in various applications. The progressive implementation of machine learning (ML) and embedded intelligence in IoT sensors has paved the way for more adaptive and autonomous systems that are capable of real-time analysis, even with constrained computational and energy resources. These advancements are crucial for developing robust, energy-efficient solutions that can perform reliably in challenging environments, such as agriculture, environmental monitoring, smart cities, smart transportation, and industrial automation.

The aim of this Special Issue is to compile the latest original research and review articles focusing on the integration of energy harvesting (EH), ML, and embedded intelligence in IoT sensors. We encourage submissions that address the challenges of implementing ML algorithms in resource-constrained systems and propose innovative solutions that advance the efficiency and intelligence of IoT networks. The topics of this Special Issue will include, but are not limited to, the following:

  • Adaptive and self-learning operations of IoT sensors;
  • Embedded intelligence and on-device ML;
  • Data collection, processing, and efficient storage mechanisms;
  • Edge computing and resource-optimized data analytics;
  • EH technologies and adaptive energy management;
  • Lightweight and energy-efficient ML models;
  • Predictive algorithms for energy optimization and fault detection;
  • Signal processing techniques enhanced by ML;
  • Anomaly detection and predictive maintenance using artificial intelligence (AI);
  • Optimization of data transmission technologies;
  • Reliability and resilience analysis of intelligent IoT systems;
  • Intelligent operation and resource management in fifth-generation (5G) and IoT networks;
  • Smart agriculture, urban infrastructure, and industrial automation applications;
  • Rapid prototyping and simulations of energy-aware AI systems;
  • Innovative approaches to hardware–software co-design for embedded systems;
  • Case studies demonstrating real-world implementations and performance evaluations.

As the need to monitor agriculture parameters intensifies, the development of new sensor nodes for data collection is crucial. These sensor types naturally require power for operation, but conventional battery-based power solutions have certain limitations. This study investigates the potential of harnessing the natural temperature gradient between soil and air to power wireless sensor nodes deployed in environments such as agricultural areas or remote off-grid locations where the use of batteries as a power source is impractical. We evaluated existing devices that exploit similar energy sources and applied the results to develop a state-of-the-art device for extensive testing over a 12-month period. Our main objective was to precisely measure the temperature on a thermoelectric generator (TEG) (a Peltier cell, in particular) and assess the device’s energy yield. The device harvested 7852.2 J of electrical energy during the testing period. The experiment highlights the viability of using environmental temperature differences to power wireless sensor nodes in off-grid and battery-constrained applications. The results indicate significant potential for the device as a sustainable energy solution in agricultural monitoring scenarios. Full article
