Introduction

Scientists create a flexible device that converts wi-fi signals into electricity. We can probably all agree that charging cables are only the worst and that we would love to reduce their presence in our lives. The new invention may give us that; engineers have developed a flexible device that collects wi-fi signals. It is not just an assembly. But it can then be converted into electricity used to power. And operate different devices without the need for wires and batteries.

The device is known as a rectenna. The name derivation was from the two words (Rectifying Antenna), a type of antenna that converts electromagnetic energy into a continuous electric current (DC).

This new device was invented by a team led by the Massachusetts Institute of Technology (MIT) and the Madrid Technical University. They use a wireless frequency antenna to capture electromagnetic waves (similar to those produced by the wi-fi network) as waveforms alternating/AC.

The waves exist sent to 2d semiconductors that turn them into a continuous electric current, producing about 40 microwatts. This energy is not great, but enough to run led lamps (light emitter diode) or silicon chip chips.

Because the device is flexible. It can exist distributed over large areas similar to wallpaper or used in small portable devices such as flexible smartphones. This area is desperately trying to appear.

We can use this technology even in medical implants and swallowable sensors. “Ideally, we don’t want to use batteries to operate these systems because if lithium leaks, the patient may die,” said Jesús Grajal of Madrid Technical University. Instead, it is best to collect energy from the environment to operate these small laboratories within the device and deliver data to external computers.

This device is not the first to convert power from wi-fi signals to electricity. This idea has been in place for some time. And engineers continue to develop it. The team has done to improve it this time is to using a different substance for the component. Which converts the ac to continuous.

In previous experiments to make this device, a silicon-like substance or gallium arsenide existed used, which is solid and expensive for use in large areas. In this flexible device, the team used MoS2, a substance of three thick atoms. And also, when exposed to certain chemicals. It imposes a phased transition between semiconductors and minerals.

The Shotki Link – Including wi-fi, Bluetooth and More

This formula exists also known as the “shotki link,” simulating the properties of the junction point in the metal-semiconductor used in the former air components. Resulting in a component that reduces parasitic (unwanted) electrical capacity and thus works more quickly.

In addition, it means that it can capture higher frequencies than other flexible components. Which cannot capture the GHz frequencies in which wi-fi is operated.

This design has allowed the device to be fully flexible and fast enough to cover most of the RF bands used by our daily electronic devices. Including wi-fi, Bluetooth, cellular communication networks and much more.”

Conclusion

This device is relatively low in more extensive metrics to exist used in more extensive applications. “What if we can develop electronic systems to wrap around a bridge or cover the entire highway or office walls and bring electronic intelligence to everything around us?

Therefore, how do you save energy for these electronics? It is what Engineer Thomas Palacios of the Massachusetts Institute of Technology and the Center for Graphene Devices. And also, 2D Systems in Micro technical Systems Laboratories said.
