“…As shown in Figure 5 g, when the wind speed is less than 5 m/s, the working mode of SM-TENG is sliding F-TENG. When the wind speed exceeds 5 m/s, SM-TENG works in contact with the rotating separated R-Teng [ 40 ]. Changing the rotational inertia or driving torque of the device, as well as changing the key characteristics of the mechanism itself at different wind speeds, such as changing the contact area of the friction layer due to the centrifugal angle, achieves good characteristics of the mechanism’s self-adjustment output with wind speed changes.…”

In recent decades, the development of electronic technology has provided opportunities for the Internet of Things, biomedicine, and energy harvesting. One of the challenges of the Internet of Things in the electrification era is energy supply. Centralized energy supply has been tested over hundreds of years of history, and its advantages such as ideal output power and stable performance are obvious, but it cannot meet the specific needs of the Internet of Things, and distributed energy supply also has a large demand. Since the invention of nanogenerators, another promising solution for fluid energy harvesting has been opened up. The triboelectric nanogenerator is an emerging platform technology for electromechanical energy conversion, which can realize the collection of fluid energy such as wind energy and wave energy. In this paper, we first introduce the fundamentals of triboelectric nanogenerators and their applications in wind and wave energy harvesting devices. We then discuss the methods of device optimization in the next development of TENG and conclude by considering the future prospects and challenges for triboelectric nanogenerator harvesting devices.

“…However, most traffic warning equipment and signal sensors are used in combination with active sensors. − The use of traditional energy sources is severely restricted by application scenarios, causing high maintenance costs and difficult monitoring and dispatching. For many wind power monitoring scenarios, self-powered sensing can improve system flexibility and perform well in application scenarios. − At present, the structural design of TENG in wind energy collection mainly includes windmill type, fan type, wind cup type, drag vane type, lift vane type, swing type, membrane tremor type, and flag type. − These types of nanogenerators can effectively collect wind energy and monitor wind speed and direction. However, there is an urgent need for a completely self-powered solution for effectively quantified wind power collection, which can respond to different wind speeds, accurately measure wind speeds, and monitor high-speed railwind disturbance to provide alarms .…”

Self-powered sensors are an important application development direction of nanogenerators. The development of fully self-powered systems that do not rely on traditional energy systems such as mains power or batteries is of great value to the future design of the loT. Such system design is not an easy task due to the detailed calculation of multiple units' energy consumption combined with smart design of minimizing the total consumption of the full system design. By converting energy such as wind energy into electrical energy and designing an indication system that simultaneously utilizes this energy, we completed a fully self-powered sensing system to transduce the wind strength of a high-speed rail. The self-powered sensor part of the system utilizes the modulus design of the pleated elastomer and at the same time achieves wind pressure-LED indication. The circuit is simplified by dropping the traditional control chips, decreasing the energy consumption, and increasing the system reliability. This crumple sensor system has a faster activation speed than that of other wind cup sensors and can sense the wind force when a train passes to protect the canopy structure. This system presents ideas for future designs of fully self-powered systems.

“…Flanges are also installed in the rotor, to which the cutting blades are attached. The purpose of this study is to investigate the various forces and stresses that are applied to the rotor axis of a typical rotator, which is affected by transient loads [5,6]. Conventional rotator models were considered for study and analysis due to their progressive cutting sequence.…”

One of the most important operations in agriculture is tillage, which has a great contribution to increasing crop yield and aeration of the soil and, ultimately, root development. Among the important tools for tillage are rotary rotators that are exposed to high and variable dynamic loads, so they are designed to have both the greatest contribution to soil agitation and high strength; It is necessary. Therefore, in this research, an L-shaped blade sample was designed for a rotator using a Biomimetic method. Due to the extensive research that has been done in the world in the field of manufacturing different types of rotators with a rotating agitator mechanism, therefore, it is necessary to study and optimize the rotator blades according to Iranian conditions. In this study, the studied variables include dependent and independent variables. Dependent variables include von Mises stress and arm displacement, and independent variables include the dimensions and geometric parameters of the Shape of the Rotator Blades. The idea for the blade design was inspired by the paw of a mole rat. Six blades were designed by simple method and biomimetic method and then by finite element method. Effects of blade angle change and design method on stress distribution, maximum displacement, maximum energy absorbed in the blade, reliability and under 400 N checked out. The results showed that in all designed models, the values of stress, displacement and energy absorbed were lower in the biomimetic design mode. As the blade angle increased, the values of the above parameters also decreased. Finally, the best model for having the least von Mises stress and the highest reliability was the blade with a Biomimetic design and a 20-degree angle.
