Scientists develop a device capable of converting Wi-Fi signals into electricity
United States and Spanish scientists have developed a flexible device to convert Wi-Fi signals to electronic devices, portable devices and medical devices.
The study published in the journal Nature magazine describes a highly flexible radio frequency antenna to make electromagnetic DC electromagnetic waves.
An antenna is a two-dimensional rectifier called molybdenum disulphide (MoS2), that is, it has only three atoms and is one of the best semiconductors around the world.
According to the study, AC signals, including Wi-Fi, when they go to the semiconductor, turn circuits or convert battery voltages to DC batteries.
In addition, the device is flexible so it covers large areas, such as the surfaces of the building.
"We have designed a new way of promoting electronic systems systems for the future in a wide range of ways to integrate Wi-Fi power in large areas," said the author of the article, Tomas Palacios, a professor of electrical engineering at the Massachusetts Institute. Technology (MIT).
In experiments, the device can produce up to 40 microprocessories with approximately 150 microwatts of typical Wi-Fi signals. It is enough to clarify simple mobile screen or silicon chips.
Most of the previously unreported mock runners can operate low-frequency so they can not capture and convert gigahertz frequencies from the mobile phone and Wi-Fi signals, according to researchers.
MoS2 material is much faster in signal turning, and it can turn it into 10 gigabytes of wireless signals and make it easy for you.
The maximum output efficiency of the current device is 40%, depending on the input of the Wi-Fi input. According to the research, the energy efficiency of the MoS2 rectifier in a typical Wi-Fi power level is about 30%.
In addition, the disposable medication device can be used to dispose of lithium toxicity.
"It is better to collect environmental energy to feed small laboratories within the body and communicate data to external computers," said the co-author of the article, researchers at the Technical University of Madrid, Jesus Grajal.
