“…In addition, silicon based PV cells have a typical energy conversion efficiency of around 20%. Studies from year 2007 up till year 2014 not only supports that fact that it is risky to depend on solar energy harvesting due to its low reliability of energy availability but also not worth in terms of installation and maintenance costs [28], [29], [39], [40]. Although a multisource energy harvester including solar is proposed in [41], it is not cost effective.…”

Condition monitoring sensors have the responsibility of reducing occupational failures or unscheduled shutdowns especially in power transmission line systems. Existing sensors that are used for condition monitoring are mostly battery-dependent. Powering up these sensors in difficult to access areas where high voltage transmission line usually runs is a challenge because batteries usually have a limited life cycle. Power sources other than batteries such as harvesting from solar energy, magnetic energy, radio frequency energy either produces insufficient energy or not entirely available all the time. Electric Field Energy Harvesting (EFEH) overcomes many of these disadvantages and provides a quality and continuous power source to be used to power up devices especially the monitoring sensors that are used in transmission line monitoring. This paper presents key aspects and drawbacks of six types of energy harvesting methods and a review of existing energy harvesters. The concept of electric field and the usage of EFEH in power transmission line system are explained and a comparison between EFEH with typical energy harvesting methods is discussed. This paper finds that EFEH devices have potential to provide sufficient energy for low powered condition monitoring sensors. Moreover, several improved EFEH approaches are proposed, and future trends are discussed.

“…Here the concern was so much into storing state information during the engine assembly rather than monitoring the health of the bolt itself. To the best of our knowledge, even if wireless sensor networks is a consolidated technology for more than ten years (e.g., [ 4 ]), we have not come across any other publication or product that monitors different properties of bolts in real time and relays gathered data to a central controller, while many works are targeting TEGs to build a reliable power supply for wireless sensor in industrial environments [ 5 , 6 , 7 ]. An interesting solution in this field is to exploit Phase-Change Materials (PCMs) to maximize the energy extracted from a thermal gradient, specifically in those cases where temperature gradients are not constant and reverse thermal gradient may cyclically occur [ 8 ], for example in airplanes during take-off and landing phases [ 9 ].…”

Thermoelectric generators (TEGs) are now capable of powering the abundant low power electronics from very small (just a few degrees Celsius) temperature gradients. This factor along with the continuously lowering cost and size of TEGs, has contributed to the growing number of miniaturized battery-free sensor modules powered by TEGs. In this article, we present the design of an ambient-powered wireless bolt for high-end electro-mechanical systems. The bolt is equipped with a temperature sensor and a low power RF chip powered from a TEG. A DC-DC converter interfacing the TEG with the RF chip is used to step-up the low TEG voltage. The work includes the characterizations of different TEGs and DC-DC converters to determine the optimal design based on the amount of power that can be generated from a TEG under different loads and at temperature gradients typical of industrial environments. A prototype system was implemented and the power consumption of this system under different conditions was also measured. Results demonstrate that the power generated by the TEG at very low temperature gradients is sufficient to guarantee continuous wireless monitoring of the critical fasteners in critical systems such as avionics, motorsport and aerospace.

“…This results in the development of internet of things (IoT) devices in which a massive number of wireless devices including sensors communicate with each other at much higher data rates and require an ultra-low power design for long-lasting operation [ 5 , 6 , 7 ]. In most cases, the sensor nodes operate on batteries and depend on the application such as a toxic environment, or inside the human body or the wall, where it is difficult to replace the batteries [ 8 , 9 , 10 ]. In addition, it requires significant resources for maintaining billions of IoT devices, providing batteries for the operation and the proper battery disposal described in [ 11 , 12 , 13 ].…”

This paper presents an adaptive control and communication protocol (ACCP) for the ultra-low power simultaneous wireless information and power transfer (SWIPT) system for sensor applications. The SWIPT system-related operations depend on harvested radio frequency (RF) energy from the ambient environment. The necessary power for SWIPT system operation is not always available and it depends on the available RF energy in the ambient environment, transmitted RF power from the SWIPT transmitter, and the distance from the transmitter and channel conditions. Thus, an efficient control and communication protocol is required which can control the SWIPT system for sensor applications which mainly consists of a transmitter and a receiver. Multiple data frame structures are used to optimize the exchange of bits for the communication and control of the SWIPT system. Both SWIPT transmitter and receiver are capable of using multiple modulation schemes which can be switched depending on the channel condition and the available RF energy in the ambient environment. This provides support for automatic switching between the time switching scheme and power splitting scheme for the distribution of received RF power in the SWIPT receiver. It also adjusts the digital clock frequency at the SWIPT receiver according to the harvested power level to optimize the power consumption. The SWIPT receiver controller with ACCP is implemented in 180 nm CMOS technology. The RF frequency of the SWIPT operation is 5.8 GHz. Digital clock frequency at the SWIPT receiver can be adjusted between 32 kHz and 2 MHz which provides data rates from 8 to 500 kbps, respectively. The power consumption and area utilization are 12.3 µW and 0.81 mm².
