Human Body Friction Electricity

Frictional electricity is created when two compatible bodies rub against one another and electrons move from one body to the other. The body that loses electrons develops a positive charge, whereas the body that gains electrons develops a negative charge.

Example: when you rub a balloon against your hair, electrons go from your hair to the balloon due to the friction. As a result, your hair becomes positively charged (electron shortage) while the balloon acquires a negative charge (excess of electrons). Your hair may stand up or adhere to the balloon due to the charge imbalance that results in an electrostatic attraction between them.

There are numerous practical uses for triboelectricity. As an example, it is applied in various gadgets to produce energy from vibrations or mechanical action. Triboelectric nanogenerators (TENGs) are made to use the triboelectric effect to transform mechanical energy into electrical energy. They have potential uses in wearable electronics, self-powered sensors, and energy harvesting systems since they can gather ambient energy sources including human movement, wind, or water flow.

Triboelectricity, also known as human friction electricity, is an intriguing phenomena that shows how friction between materials can result in the creation of an electric charge.
