Introduction

The need for new, efficient, flexible technology is growing. The world demands faster, stronger, and more reliable methods of travel, working, communications, monitoring, and interaction. Innovative solutions can meet customer needs while fulfilling future objectives and delivering on its objectives. For example, engineers worked tirelessly to design an usable electrical energy harvesting system featuring energy scavenging and super capability in an energy-rich compact design with space efficiency and low-profile construction (Nguyen).

Different industry sectors like automotive and consumer goods seek to incorporate wireless technologies into their products(Green & Linder 2007). This proves to be the critical factor in generating hybrid power consumption sources such as batteries, ultracapacitors or fuel cells (MacKay-Shallin).

Conventional renewable rf energy sources such as solar, wind, and water can meet the demand of global power generation at a given time. However, they are not dependable enough to provide electricity on a 24/7 basis because they require sunlight or wind – just not at night or on a cloudy day. Thus, an alternative power source is needed to produce electrical energy even without these factors(Green).

Different types of Energy Storage Devices

Different energy storage devices can be used as a power source for electronic equipment. They include:

a) Batteries

b) Capacitors

c) Ultracapacitors

d) Fuel Cells

Conclusion

Due to the increasing demand for energy storage and management, we can use renewable power sources such as solar, wind, and water. However, these source needs sunshine and wind for generating electricity which is not available every time. Therefore, for a continuous supply of power, we need a new renewable mechanical energy source that can be used 24/7, which is still under research.

Abstract

Today, energy storage systems are being used to power various devices. These devices include wearable technology, wireless sensor nodes networks, and renewable energy sources, including solar panels. The growth in this industry has led to new energy harvesting applications for these devices. However, one of the main problems is that these batteries can be heavy and unsuitable for wearables. This paper will discuss different energy harvesting technologies, including triboelectric thermoelectric generation, along with a specific type of solar cell called a dye-sensitized solar cell (DSSC). The focus will be on static electricity collection because it does not require movement from the wearer.

To create efficient generators from human movement, we need efficient materials developed over the years by researchers at the University of Wisconsin. This study has produced the required components which will allow for efficient generators that can be used to power wearable devices like watches, pacemakers, and other medical equipment. In addition, the use of these materials has created a lightweight generator and requires only one electron donor component.

This paper will also cover ultracapacitors as an energy storage device featuring supercapacitor applications and electrochemical double-layer capacitors (EDLCs). Conclusion

Energy storage devices

are used to power devices such as wearable technology, wireless sensor networks, and renewable sources. The growth in this industry has led to new applications for these batteries or capacitor-based devices. Due to the weight of batteries, they cannot be used for wearables. This paper will discuss different energy harvesting technologies, including triboelectric thermoelectric generation, along with a specific type of solar cell called dye-sensitized solar cells (DSSC). The focus will be on static electricity collection because it does not require movement from the wearer.

Batteries are being used to power electronic equipment today. However, some limitations include size and weight, making them inappropriate for wearable technology. Energy storage systems like ultracapacitors offer an alternative that can be charged up and used when an energy source is not available. They do not require a long period to charge, unlike batteries. In addition, they hold more power in a smaller space.

For electronic equipment to work using solar power, the panels should produce at least 1 volt of power. However, this type of panel does not generate enough voltage to charge a typical electronic device such as a watch. Dye-sensitized solar cells (DSSC) are designed to address this problem and create flexible thin-film solar panels. This paper will discuss the use of static electricity, and various types of generators developed over the years by researchers at the University of Wisconsin. A generator will be created using efficient materials developed over the years by researchers at the University of Wisconsin. This study has produced the required components to allow for efficient generators that can be used to power wearable devices like watches, pacemakers, and other medical equipment.

A schematic of energy harvesters and storage system in a watch-like device configuration. An energy harvesting and storage unit is shown in a rectangle in the top left corner. In contrast, the upper right-hand corner shows a diagram showing charge distribution in various compartments within the same unit. All symbols are explained in the text.

The process begins with thermoelectric generators (TEGs). However, these generators are not suitable for wearables because they cannot convert high temperatures to electrical power. TEGs require a temperature difference between two different conductive plates (a thermoelectric semiconductor) to produce an electric voltage. The study called "Electricity Generation by Triboelectrification" will be discussed below.

Further research has focused on triboelectric nanogenerators (TENGs). A TEG requires a significant temperature difference not found within the human body or any object people encounter during their daily activities. However, the motion of rubbing particular objects together leads to an accumulation of electrons on one surface and reduction on another surface, leading to a voltage between them. This electric potential can be used to power devices like watches which typically operate at low voltages (1-3 volts). However, the disadvantage of this generator is that it loses efficiency with increases in frequency or speed in harvesting energy because the triboelectric charges are pulled away from their respective material, which cannot support the same amount of charge across its surface.

Static electricity is an additional source that can be exploited to provide energy for wearable devices. The technique involved will harvest static electricity by pulling electrons off the wearer's body using a high electron affinity material. For example, a low work function metal will have a high electron affinity, while polymers have very low electron affinities and cannot effectively pull electrons off human skin. Two examples of materials used to design a static electricity harvesting device are discussed below.

The rectangle on the bottom left corner shows a schematic top view of a triboelectric nanogenerator. The two arrows indicate movement bringing about static electricity, which this energy-generating device can harvest. A potential drop across each electrode is indicated by the double-ended arrow under each electrode for illustrative purposes only since that does not cause an actual voltage difference between one end and the other end. In addition, a push-pull graph indicating different modes of operation for this type of generator facing toward and away from the reader, respectively, is illustrated in the lower right-hand corner. Finally, the inset diagram shows generic computer-simulated data plots for voltage and current as a function of time for a triboelectric nanogenerator.

In the first method, materials with high electron affinity will create a textile-based generator, as shown below. In this process, two electrodes are attached to opposing ends of textile material and apply an electric potential across it. Electrons are pulled from the surface of human skin by this electric field because it has a higher electron affinity than the surrounding air, which leaves positively charged ions on top of the skin. Thus, a voltage difference occurs between two electrode surfaces due to the accumulation of these mobile ions on one surface and depletion on the other, leading to an electric potential between them. This type of system is called supercapacitive textiles.

High electron affinity materials like n-type semiconductors, carbon nanotubes (CNTs), and graphene-coated CNTs can be used as electrodes on this type of generator. On the other hand, polymers or p-type semiconductors can be used as the opposite electrode because these materials have low electron affinities compared to human skin, which means they cannot effectively pull electrons off the body. Using textile material is inexpensive to produce, flexible, stretchable, breathable, and comfortable to wear. Furthermore, highly conductive textiles are needed to apply an electric field uniformly across this material.

A polymer TENG is shown above in the rectangle on the left-hand side of the image. Two gold electrodes are attached to opposing ends of a flexible polymer sheet, and an electric potential is applied across this sheet. The electrons are pulled from the surface of the gold electrode due to its high electron affinity because it is an n-type semiconductor that leaves positively charged ions on top of the electrode after pulling off electrons.

A CNT textile TENG is shown in the rectangle in the right-hand corner above. Two CNTs are used as electrodes with dissolved zinc chloride acting as an electrolyte in an eight wt% polyvinyl alcohol solution for ionic conduction through a polymer matrix that separates these electrodes. Then, an electrical potential can be applied between them by connecting this textile to a voltage supply.

The efficiency of textile-based generators is determined by the materials and the structure used and other factors such as their configuration on clothing, positioning on the body, and humidity. Depending on output requirements, these generators can also be connected in series or parallel. Typically, nanogenerators will power small electronic devices such as wearable electronics. In contrast, textile-based generators will charge batteries since they have higher power densities than nanogenerators. Two examples of the placement of these generators are shown below:

s use triboelectric effect occurs when certain surfaces rub against each other, causing one surface to lose electrons while another gains electrons due to this rubbing action. A triboelectric nanogenerator (TENG) is an electrical generator that harvests energy by using the triboelectric effect. For example, nylon and Teflon are two materials that can be used as electrodes in this system, with air or water as the dielectric medium due to their high static-to-electricity conversion efficiencies. When these surfaces slide against each other, they gain/lose electrons leading to a change in electric potential between the two surfaces, eventually harvested by the semiconductors attached.

Another critical aspect of TENGs is that they can be designed for specific output requirements such as voltage and current, depending on the application area. For example, one of these generators has multiple polymers connected in series, parallel, or both to improve output voltage. The image below shows an example of this type of design where the height and weight of each polymer are used to determine its contribution to the overall output voltage.

This textile-based generator has five different elastomer layers with alternating triboelectric materials at their surface to generate an electric potential between them due to the triboelectric effect. For example, polydimethylsiloxane (PDMS) is at the bottom while polyacrylonitrile (PAN) is on top, along with other types of wax-coated fabrics acting as dielectrics for separating electrodes to avoid contact electrification. A TENG using these kinds of energy harvesting systems was shown to work well even in humid conditions, and it was also capable of charging two real smartphones at 1.5 V and 2.4 A for an hour using only the energy generated by the user walking on one square meter surface of this TENG.

Energy harvesting can provide extremely low-cost power sources even if these systems are very inefficient. This is because their efficiency may not need to be high, given how they will eventually be used for powering small electronic devices like wearable electronics that require low currents. Also, since these generators may contain multiple materials, production costs might be lower due to simpler manufacturing processes needed than nanogenerators with a limited number of configurations depending on the desired voltage and current output requirements. However, even though energy harvesting devices have some clear advantages, various challenges must be faced before the general public can widely use them. For example, making an efficient generator using multiple materials is challenging since their performance usually varies depending on environmental conditions.

Another challenge is the size of TENGs which cannot be more prominent due to friction forces causing them to break apart. This also means they will not have enough surface area to gather the sufficient kinetic energy needed to provide significant amounts of electric power. However, this issue could be solved by using clothing with unique textiles explicitly designed to increase surface area contact between textile fibres and human skin, thus enabling more powerful output generation from these generators. Moreover, this potential solution could also be used with flexible solar cells to improve power output. Overall, triboelectric nanogenerators are still in their early stages of development, considering the amount of research currently being done on them, especially with other energy harvesting technologies like thermoelectrics and photovoltaics. Even though they provide low-cost sustainable sources of electric power, there is still more work to improve these generators by improving their efficiencies without compromising their minuscule sizes, which is the most significant advantage they have over most other renewable energy harvesting systems.
