Static Electricity &
Electrical Charge
In every friction, Static electricity, and Electrical Charge are always involved as created when two materials come into contact or are rubbed together. When the materials are in contact, electrons can be rubbed off of one object and onto the other. It doesn’t mean that any two materials rubbed together will cause electrons to move. Some materials are more willing to donate electrons, and others are more likely to accept electrons.
In this case, P-TENG is used as an alternative renewable resource of electricity, and our project materials are made from paper and polyethylene material, which are materials that easily gain electrons to accumulate faster energy. Moreover, when the surface of the
​graphite (carbon) contacts anything, it would result in static friction. Flowing the accumulated electrons in the paper through the cable has the potential to light a bulb.
Non-contact forces, such as electrostatic forces, pull or push on objects without making physical touch with them. The charge can be transferred from one surface to another when certain materials are rubbed together. Like charges repel while unlike charges attract. Similar to this concept, when wheels of moving objects scrape against the ground, one loses electrons and the other receives them, resulting in an attraction.
Electricity
The word "electricity" is derived from the Greek word "elektron," which means amber. Atoms and charges like electrons, protons, and neutrons make up electricity necessary for our project to function and generate energy. As electrons flow via an electrical conductor, dynamic or current electricity occurs. Graphite or conductive ink are the two options for the project's conductor materials.
Renewable Energy Source
​There are different renewable energy sources like sun, air, geothermal energy, and friction. Friction is present everywhere. As friction converts to electricity, the interaction of thermal energy rises, allowing for the harvesting of static electricity from friction in triboelectric nanogenerators, an alternative renewable energy source.
Triboelectric Series
The triboelectric series is a list of materials that identify if the materials can absorb positive or negative charges and the relative strengths of those charges based on their position on the list. Materials that are most likely to lose electrons are Rabbit Fur, Hair, and Glass, and the materials that are most likely to gain electrons are Teflon, Polyethylene, and Rubber Balloon.
Triboelectric Effect
A type of contact electrification known as the triboelectric effect occurs when some chemicals are separated from another substance with which they are associated, causing them to become electrically active. The triboelectric effect is what causes a balloon to become electrically charged when you rub it against your hair, or a car to become set from its tires rolling on the road resulting in a shock when you touch the door handle.
Friction Force
​ A force known as friction prevents relative motion between surfaces that are in touch. One of the more basic features of friction is that it always runs parallel to the surfaces with which it makes contact and opposes any motion or attempted motion of the systems concerning one another.
Electromagnetism
The two major elements of electromagnetism are electricity and magnetism. Electric currents can produce their magnetic field. According to the rule of Magnetic Force, a magnetic force is equal to the charge of the particle multiplied by the velocity and strength of the magnetic field. This finding explains that a larger velocity will be equal to a larger magnetic force, while a lower velocity will result in a lower magnetic field. In referring to the topic and its relation to Electromagnetism, faster velocity must be created to produce a higher source of electricity.
