Researchers from Switzerland have devised a method that allows the use of wooden floors Collect electricity while walking on. This technology is called a nanogenerator and can generate enough electricity from walking to power the light bulb under test. The researchers of this project improved the wooden floor used in their nanogenerator by integrating a combination of a special silicone coating and embedded nanocrystals.

The result of their work is a power generation The device, it is said that the electricity it harvests is enough to power an LED bulb and small electronic devices. The researchers created their experimental nanogenerator by inserting two pieces of functionalized wood between the electrodes. These wood chips are charged by contact and separation during walking. This is the so-called three-electric effect.

One of the biggest challenges of using wood flooring to generate electricity is that wood is neutral in nature, which means that wood basically has no tendency to gain or lose electrons, limiting its ability to generate electricity. A major challenge is how to make wood attract and lose electrons.

In order to achieve the gain and loss of electrons Ability, the researchers smear a piece of wood with polydimethylsiloxane (PDMS), which is a type of silica gel that can gain electrons when in contact. The other piece of wood is functionalized with nanocrystals grown in situ, which are called zeolite imidazole framework-8 (ZIF-8). ZIF-8 is a network composed of metal ions and organic molecules. It has a greater tendency to lose electrons than to gain electrons.

The researchers also investigated different types of wood to see which wood has the best power generation effect. They also investigated whether the grain direction in the wood is related. In the end, the research team found that the three-electric nanogenerator made of radially cut spruce performed best. This kind of wood happens to be a commonly used building material in European countries. Currently, researchers are working hard to optimize their creations.
