“…Since this study is mainly about piezoelectric materials that are used in energy harvesting with planetary gears, the following description mainly concerns piezoelectric material such as the sensor case, not the actuator. There are three operation modes in piezoelectric material: d 15 (3) means that the voltage is generated along the z-axis, and this is for both modes. The second number is an indication of the direction of the applied force.…”

“…Further, there are issues such as volume, weight, and short lifetime of batteries, which is much shorter than the WSN life, and batteries must be changed frequently. Consequently, researchers must find an alternative power source by focusing more attention on energy-harvesting technology [2,3].…”

In the present study, a rotational piezoelectric (PZT) energy harvester has been designed, fabricated and tested. The design can enhance output power by frequency up-conversion and provide the desired output power range from a fixed input rotational speed by increasing the interchangeable planet cover numbers which is the novelty of this work. The prototype ability to harvest energy has been evaluated with four experiments, which determine the effect of rotational speed, interchangeable planet cover numbers, the distance between PZTs, and PZTs numbers. Increasing rotational speed shows that it can increase output power. However, increasing planet cover numbers can increase the output power without the need to increase speed or any excitation element. With the usage of one, two, and four planet cover numbers, the prototype is able to harvest output power of 0.414 mW, 0.672 mW, and 1.566 mW, respectively, at 50 kΩ with 1500 rpm, and 6.25 Hz bending frequency of the PZT. Moreover, when three cantilevers are used with 35 kΩ loads, the output power is 6.007 mW, and the power density of piezoelectric material is 9.59 mW/cm3. It was concluded that the model could work for frequency up-conversion and provide the desired output power range from a fixed input rotational speed and may result in a longer lifetime of the PZT.

“…However, limitation of power source and batteries, such as volume, weight, and short lifetime, which is much less than the WSN life, changing the batteries frequently, and devices in hard reach area [3]. All these limitations make the powering of microdevices and WSNs using energy harvester considering a feasible approach in our environment due to its small size, low power consumption, and special working environment [4,5].…”

Rotational Piezoelectric Energy Harvesting (RPZTEH) is widely used due to mechanical rotational input power availability in industrial and natural environments. This paper reviews the recent studies and research in RPZTEH based on its excitation elements and design and their influence on performance. It presents different groups for comparison according to their mechanical inputs and applications, such as fluid (air or water) movement, human motion, rotational vehicle tires, and other rotational operational principal including gears. The work emphasises the discussion of different types of excitations elements, such as mass weight, magnetic force, gravity force, centrifugal force, gears teeth, and impact force, to show their effect on enhancing output power. It revealed that a small compact design with the use of magnetic, gravity, and centrifugal forces as excitation elements and a fixed piezoelectric to avoid a slip ring had a good influence on output power optimisation. One of the interesting designs that future works should focus on is using gear for frequency up-conversion to enhance output power density and keep the design simple and compact.

“…Hao et al 17 increased the performance of their piezoelectric pulse generator with −0.2 and 0.2 V between 306 and 312 Hz operating range. Kherbeet et al 18 the experimental results showed that two triangular cantilevers at designated natural frequencies of 85 and 95 Hz combined in vertical direction had the ability to generate 11 979.527 μW for a volume of 1 cm 3 which is high enough to generate a wireless sensor. Wang et al 19 developed a compressive‐mode high‐power‐density PZT for harvesting vibration energy from spring suspension systems for piezoelectric energy harvesting and powering wireless sensors in spring suspension systems.…”

In this study, an energy harvester using the mechanical vibrations created by the airflow on piezoelectric transducers outside a vehicle was designed, produced and introduced. The introduced harvester has an energy production potential of μJ level. Given an energy power, very little power but long-term harvest was achieved. While the introduced vehicle was driven at speeds of 70, 90, and 110 km/h, energy production at location angles of 0 , 45 , and 90 was determined for each speed. Vehicle speed, location angle, airflow outside the vehicle, and harvester output were measured. Output voltage of the harvester was found to be directly proportional to vehicle speed. Output of the transducers was combined using a circuit topology that would maximize the output voltage. Thanks to this circuit highest output voltage was obtained from the location angle of 0. Thus, maximum output power was obtained at a speed of 110 km/h for 0 location angle. This research develops a new design method for efficient and practical energy generated by piezoelectric sensors placed on a vehicle from the vibration of the airflow around a moving vehicle. This energy harvester can meet the internal micro energy needs of the vehicle with an external battery.
