Scientists have created a kinetic generator in the form of a film for powering gadgets

Ученые создали кинетический генератор в виде плёнки для питания гаджетов (2 видео) We have repeatedly been shown developments that are able to collect kinetic energy from human movements in order to further use it to fuel wearable and other gadgets. It appears that Michigan State University employees have progressed farthest in creating such a system. We are talking about the so-called biocompatible ferroelectro-nanogenerator, which is very flexible and at the same time no thicker than a sheet of paper. Engineers have already managed to conduct successful tests with the invention. The device in the form of a film was able to supply power to a flexible keyboard, 20 LED bulbs and a touch screen – the latter worked by touching or pressing a finger on the film. The invention consists of a silicon wafer on which layers of biocompatible materials are located, namely silver and polymer foam with ferro- and piezoelectric properties. Each layer is supplemented with metal ions. All this ultimately allows you to generate electricity with every mechanical impact. The film folded several times increases the magnitude of the voltage exponentially. “The film can be placed in one layer on a large device, for example, on the screen of a smartphone or tablet, but if it is folded several times, it will start to produce more energy. A small kinetic generator can be mounted in clothes, for example, in a shoe heel, and then at every step, useful and necessary electricity will be generated to power smart clothes and other smart attributes of a person of the present and future, \it’s necessary to charge from the mains during the week, since it can receive the necessary energy for work from the movement of the human body, ”Sepulveda states. That is, we will understand for ourselves that physical activity will be important not only for our body, but also for the work of the ubiquitous gadgets, which over time will become more. That’s just about the life and cost of products based on development, as well as about the date of the appearance of the first commercial products based on it, no one says anything.
