The World Environment Conference was held in Copenhagen a few days ago. All countries in the world are now working together to prevent global warming. On the one hand, stopping the release of harmful chemicals into the environment and using alternative environmentally friendly fuels is the main duty of the people of the world. As a first step, the developed world as well as the least developed or developing countries have started working to stop the emission of carbon dioxide and carbon monoxide in the atmosphere. In addition, the people concerned are working to find alternative ways to deal with the energy crisis. They are especially interested in using solar energy. In this direction, it can be said that in the near future solar energy will be the main energy system. With the advancement of science, we are constantly getting acquainted with new technologies. Every discovery is making our life journey easier. Our current daily life cannot be imagined without electronic technology. From small electric devices to medium or large devices are our constant companions. While running these devices we are constantly suffering from power problems. I see that there is no charge in the device, then I see that there is no charge system. Scientists have been able to discover some excellent power technologies while working to solve these problems. On the one hand, they are very environmentally friendly and on the other hand, they are very important. Let's get acquainted with such technology. At the same time, let's know the benefits.
Engineers at Princeton University have discovered an energy-generating rubber film that can be used to power various devices in the human body (such as breathing, walking) through electronic devices such as pacemakers or mobile phones. The material made of ceramic nanoribbon is inserted into the silicone rubber sheet. When it is bent, electricity is generated and can efficiently convert mechanical energy into electrical energy.
According to the discoverers, if this material is used in shoes, energy is generated by collecting the pressure generated during walking or running. With the help of which the electrical devices can be run. If attached to the side of the lungs, the material sheet can power the chest pacemaker with the speed of inhaling and exhaling. As a result, there is no need to replace the battery with repeated operations for the power of the pacemaker.
Silicone is biocompatible, meaning it has been used as a cosmetic implant and medical device. Michael Mac Alpin, a professor of mechanical and aerospace engineering at Princeton, is the developer of the project. "This device that generates electricity can be implanted in the human body in the long run," he said. Moreover, the human body will not reject them.
To produce this material, researchers first constructed lead zirconate titanate (PZT) nanoribbon very finely. These are so narrow that one millimeter can be placed 100 feet side by side. PZT is a ceramic material that is ‘piezoelectric’ which means it generates an electrical voltage when pressure is applied to it. PZT is the most active of all piezoelectric materials. Eighty percent of the energy applied is converted into electrical energy.
Another piezoelectric material is quartz. PZT is 100 times more active than quartz, said McAlpine. He added, ‘The amount of power needed to produce electricity cannot be generated by anyone walking or breathing. So we will use the most active material in this work.
Electricity is generated when the rubber sheet is bent. Similarly, when electricity is applied to the material, it bends. This is opening the door to some more possibilities. For example, this formula can be used to use microsurgical devices, said Mac Alpin. ‘The best thing is that it can measure the electricity generated,’ said Iki, who is working with Mac Alpin as a postdoctoral researcher. If we can make these chips better, we will be able to make bigger sheets in the future that will generate relatively more energy.
