“…In a lot of work on PMGs, designers are limited to the performance of PT [89][90][91], the objective of these works consists of determining the optimum load of the designed PT. However, as we mentioned above the major application of any process of EH is the power of the WS [92].…”

This paper will present a complete discussion in recent design strategies for harvesting vibration energy using piezoelectric cantilever transducers. The interest in this primary energy source is due to its presence in non-negligible quantities in most of the engines used in the industrial process. Previous work has shown that it is possible to harvest significant amounts of energy capable of supplying a wireless sensor (WS) node. However, in most research, only one step of the energy conversion and utilization chain is studied. Starting from the definition of the different design issues for a piezoelectric micro generator (PMG), the leading optimization solutions will be reviewed in this paper. Based on the findings, the quantification of the data transmission range of wireless sensor nodes powered by a PMG is proposed to support the objectives envisioned by Industry 4.0. The vibration characteristics taken from mining locomotives that have not yet been treated previously are used to illustrate the improvement of the various optimization solutions. Through our objectives, this work offers a comprehensive discussion on the use of vibrational energy by wireless sensors, bringing together the fields of mechanics, electrical, electronics, and wireless communications. The theoretical basis for each design stage is provided through the design equations. Based on actual measurements of ambient vibration, it is demonstrated, considering an optimal design of the PMG, that a WS could transmit data beyond 1 km for physical phenomena to be controlled every 7 min.Energies 2020, 13, 63 2 of 28The data collected by WS are transmitted wirelessly to BS. Given the advantages offered by the WS, namely flexibility, ease of deployment, low cost, they are now playing a vital role in the industry 4.0 [8]. More specifically, in the industrial environment, WSs are used in the automation system [9], operations control, system monitoring (humidity, temperature, fire alarm, dust index, toxic gas, and pollution) [9,10], and motion control [11]. In most of these industrial applications, WSs are placed in difficult-to-access locations (mining crushers for example) and maintenance operations for the replacement of batteries can be costly.This issue of energy autonomy of WSs has given rise in recent years to a new field of research known as energy harvesting (EH) [12]. Energy harvesting is the process of converting ambient energy into electrical energy; the most targeted application is the power supply of the WSs.EH technologies differ from one another depending on the nature of the used primary energy source. The main considered sources are the internal light, electromagnetic energy, vibration, and heat [13]. Among these primary sources, vibration abounds in the industrial applications due to the many engines used in most processes [14]. Concerning the specific case of the mining industry, crushers that operate 24 h a day, mining locomotives for the transport of personnel and minerals, trucks, are examples of sources of vibration.A lot of rese...

“…20 With regard to the researches initiated by Mouapi A et al, a piezoelectric cantilever beam was placed under the front passenger seat to generate electrical energy, but available vibration displacement was rather limited. 21 A method was put forward by Viet NV et al who used rotating machinery structure and piezoelectric materials for energy recovery but without fully considering the difference caused by gear pitch. 22 An energy harvesting system using piezoelectric cantilever was designed, in which the speed bump could be triggered twice in the process of shock compression.…”

A cantilever‐based piezoelectric energy harvesting generator driven by an automatically ‐switchable double‐gear is designed, to assemble the linear‐to‐rotary motion translation and achieve a continuous recovery efficiently by piecewise harvesting. On the basis of identifying the road tolerance grade, an investigation is conducted into the relationship between the gear pitch, vehicle speeds and the energy. A value‐taking method and switching principle are proposed for the gear pitch of the double‐gear under comprehensive driving conditions. According to the tests of two road sections, the results of the simulations show that the automatically ‐switchable double gear can maximize the piezoelectric vibration energy harvesting efficiency under comprehensive driving conditions and road surface with varying tolerances. Meanwhile, results concerning the device experiments indicate that the harvesting efficiency could be improved by 131.66% (76.70%) and 9.37% (22.38%) compared with the single gear with its pitch of 3 mm and 10 mm, respectively.

“…The sun [7] and the wind [8], for example, can generate significant energy that can be used on a national grid. At low power levels, however, the sources of energy such as vibration [9] [10], radio waves [11], human activity [12], heat [13], and the internal light [14] was recently considered as alternative sources to power WSN. Although energy harvesting techniques allow considering immortal sensors nodes, it remains nonetheless that the performance of the sensor node is related to the quantity of recovered energy.…”

Wireless sensor networks (WSNs) offer an attractive solution to many environmental, security and process monitoring. However, their lifetime remains very limited by battery capacity. Through the use of piezoelectric energy harvesting techniques, ambient vibration can be captured and converted into usable electricity to create selfpowering WSN which is not limited by finite battery energy. This paper investigates analytically and experimentally the performance of a WSN powered by a Piezoelectric Energy Harvesting System (PEHS) and a material block-level modeling considering most key energy consumption of a wireless sensor node in a star topology network is proposed. By using real hardware parameters of existing components, the proposed model is used to evaluate the energetic budget of the node. The sensor node performance is evaluated regarding transmit packet size, duty cycle and the number of nodes that can be deployed. From the spectral properties of the available vibration inside two moving vehicles (automobile and train), the maximal recoverable power for each type of vehicle is estimated. Using a PEHS based on a cantilever beam optimized for low-frequency applications, 6 mW power is recovered in the case of the train while a 12.5 mW power is reached in the case of the automobile. It is observed that the sink may not operate with the recovered energy. However, the sensor node can sense and transmit data with a maximum size of 105.5 kbits when the duty cycle is 4 × 10 −15. It is also achieved that the node is most effective when the measured physical phenomena vary slowly, such as the variations in temperature due to thermal inertia. Considering an optimized PEHS based on non-linear processing, it is shown that the sink can operate for 190% improvement of the recovered power.
