چکیده

Energy-harvesting technologies are fundamental in enabling the realization of ‘‘zero-power’’ wireless sensors and implementing the Internet-of-Things (IoT) and machine-to-machine (M2M) communication. Their increasing utilization in low-power and power-efficient sensors and electronics could potentially find application in numerous critical areas ranging from health, agricultural, structural health monitoring to logistics, localization, and security. Energy-harvesting devices, including solar panels, piezoelectric devices, thermocouples, and RF energy scavengers, can dramatically extend the operating lifetime of nodes in wireless sensor networks (WSNs). Furthermore, this technology enables a completely battery-less operation and reduces the operation cost of WSNs, which is mainly due to battery replacement, thus making it very important for a sustainable ‘‘nearperpetual’’ WSN operability. Current methods for deploying large-scale sensor networks involve miles of cabling that provide source power and collect data, or battery-operated wireless sensors, which pose a serious environmental risk with the disposal of billions of batteries every year. While these methods are necessary in some situations where real-time data or harsh environments prohibit manual monitoring of critical environment parameters, the cost, installation difficulty, and maintenance rarely justify their use over manual inspections and monitoring. This is where the concept of energy harvesting comes in. Energy harvesting is the process by which energy is derived from external sources (e.g., solar power, thermal energy, wind energy, electromagnetic ambient energy, salinity gradients, kinetic energy, etc.), captured, and stored in order to power small, wireless autonomous devices, like those used, for instance, in wearable electronics and wireless sensor networks. Such technologies could play a critical role in the first real-world implementations of IoT, M2M communication systems, wearable biomonitoring systems and generally, the first autonomous wireless ‘‘smart skins.’’ ‘‘Smart skins’’ are cognitive, intelligent skins that sense, wirelessly communicate, and, in the future, will be able to modify environmental parameters using simple passive radiofrequency identification (RFID) technology. These skins can be applied everywhere, be it a shelf lining in a grocery store or the outside of a Boeing 787, while maintaining an unobtrusive and lightweight form factor similar to the application of a decal sticker. Smart skins are ‘‘zero-power’’ devices, meaning they scavenge their own energy using ambient electromagnetic, solar, thermal, mechanical, This special issue covers recent advances in energy-harvesting and energy-scavenging systems with a focus on numerous ‘‘renewable’’ transducer technologies as well as emerging applications.
