A group of scientists have invented a machine that converts Wi-Fi signals into electricity, powering devices without a battery.
With the creation of AirPods, wireless charging and voice command, our desire to be ever-connected is becoming increasingly physically unconnected.
With that in mind, it was only a matter of time before another new technology was introduced, this time offering a way for devices to run without the need for a physical battery.
According to MailOnline, the machine created by a team at the Massachusetts Institute of Technology, is a small two-dimensional device, powered solely by Wi-Fi waves passing through it
A new rectenna, a type of antenna, captures the waves and converts them into wireless energy using a cutting-edge semiconductor. As a result, Wi-Fi could become a widespread power source.
The team claim the new invention could power everything from large-area electronics, wearable electronic accessories and even medical devices, which could beam data to doctors.
The conversion of Wi-Fi energy to useful direct current requires a piece of equipment known as a rectifier. Traditionally they are thick and inflexible, but for this creation the researchers used a thin and malleable material known as molybdenum disulfide (MoS2), which is one of the thinnest semiconductors in the world.
We could be saying goodbye to batteries with this invention!
