According to a new research, people will soon be able to have smartphones and other tech gadgets which will not need an electric charger to power up. Yes, according to researchers at Michigan State University, the time is not far away when devices will be charged using the energy generated by the movement of the user. So, no need of plugs and no need of powering up. These researchers have made a film-like device called a nanogenerator. Using the new device, they were able to charge an LCD touchscreen as well as a flexible keyboard. The device was also able to provide power to 20 LED lights. The nanogenerator was pushed down to create the energy and there was not battery involved in the whole process.
These tests suggest a time when devices will be powered solely using the users’ movement, and that time is not far away. The more interesting feature of the device is that the users will be able to fold the film like device to generate even more power. The new technology has been named as ‘biocompatible ferroelectret nanogenerator’ or FENG. The device is unimaginably thin and can be fitted inside various devices. In the examples given in the report, when the LED lights were tested, the film was the size of a palm but when the touchscreen was testes the same thing was almost finger sized.
Nelson Sepulveda, the lead investigator of the project, wrote, “Each time you fold it you are increasing exponentially the amount of voltage you are creating.” He added, “You can start with a large device, but when you fold it once, and again, and again, it’s now much smaller and has more energy. Now it may be small enough to put in a specially made heel of your shoe so it creates power each time your heel strikes the ground.”
This technology cannot be worked on smartphones yet, still, such a massive stride suggest that the day is not far away. Sepulveda said, “What I foresee, relatively soon, is the capability of not having to charge your cell phone for an entire week, for example, because that energy will be produced by your movement.”
