We use different tablets daily,telephones, household appliances, all kinds of devices for taking care of ourselves and our home, but along with this, the amount of energy consumed by us also increases. Given that our needs for this useful resource are increasing every day, we can make a logical conclusion that a new energy problem is brewing. Fortunately, scientists studied the problem of energy shortages and found perhaps the most abundant and sustainable source of renewable energy.
How does a triboelectric nanogenerator work?
Even in ancient Greece, noticed that if rubbedpiece of amber on the animal’s hair, it will begin to attract small particles and dust. The phenomenon in which two dissimilar materials exchange charge during friction is commonly called the “triboelectric effect”. It was it that inspired scientists to search for a way to collect static energy from the ocean, air, and even the movement of our body.
In 2012, a team of scientists developed the firsttriboelectric nanogenerator (TENG). TENG has a similar principle of operation as static electricity: two materials, which are opposite in structure, exchange energy and accumulate opposite charges in themselves. If electrodes and wires are attached to such oppositely charged structures, then the resulting current is able to charge some types of devices.
A team of research scientists conducted severalexperiments, during which it turned out that if you put a grid of 1000 spheres in the ocean, then the generated energy will be enough for a standard bulb to work. Thus, a grid measuring approximately 500 meters is capable of generating energy for a small city. Scientists do not want to stop at the achieved results and plan to create a matrix of generating spheres with an area approximately equal to the state of Georgia.

Shoes with ports for charging the phone
In China, thanks to the new TENG technology, alreadysell triboelectric powered air filters. In addition, in the next two years, it is planned to release shoes with nanogenerators and ports for charging devices. During an active walk, the shoes generate enough energy to charge the phone and other modern gadgets.

It should be noted that most newThere are many shortcomings in technology. As often happens, the invented energy source is already actively criticized by environmental activists due to the lack of any information about the potential harm of the latest generators to marine life. In addition, the question of whether it is possible to create mass production of spherical generators and put them into practice does not yet have its own worthy answer.
