Zurich: This trend is less common in Pakistan, but in the homes and offices of the United States and other countries, a layer of wood is laid on the floor. Now a thin layer of silicon can be applied to this wooden floor and a metal ion can be added to it to make electricity while walking.
Theoretically, with this eco-friendly technology, it is possible that even an LED bulb can be lit by people’s mobility. In this way, even more electricity can be generated from this floor and steps in an event and conference etc.
We know that certain types of materials create a charge when they meet or separate from other types of materials. This phenomenon is called ‘Triboelectric effect’. In it, electrons descend from one surface to another. Substances that take electrons are called tribo-negative and those that give electrons are called tribo-positive.
That’s why ETH Zurich professor Guido Penzrasa and his research colleagues applied silicone to a wooden tile-like sheet. Silicon wood now begins to take in electrons when attached to an object. Nanocrystals were then added to the second panel. These nanocrystals consisted of a ‘zeolite immaterial resolutical framework 8, abbreviated as ZIF8. It is a compound that contains metal ions and some organic molecules. These crystals are characterized by the loss of electrons. In the language of physics, this process is called ‘functionalization’.
Thus, the rate of electron taking and giving has increased by 80% as compared to ordinary wood. Thus, walking on two layers of wood must generate enough electricity to light an LED bulb. Thus, when a force of 50 Newtons is applied to a piece of wood 2 cm wide and 5 cm long, this pressure produces 23 volts of electricity. In this way, small bulbs and other hand tools such as calculators can be operated from ordinary A4 paper sized wood.
Scientists believe that silicon coating is an environmentally friendly process and can be used to generate electricity.
