Can radio frequency energy be converted into electrical energy?

(Leon) Recently, the British startup Drayson Technologies, launched a new type of charging technology Freevolt, which is characterized by the ability to convert radio frequency signals into electricity for wireless charging of mobile devices, which has a wide range of application prospects.

The core of Freevolt technology lies in the collection of radio frequency signals, which are actually ubiquitous in cities, such as various sensors, signal lights, mobile networks, etc. Although the energy emitted alone is not much, it is very impressive when combined together. . Converting this energy into electricity can provide electricity for mobile phones, bracelets and even smart home devices.

Drayson Technologies has demonstrated an actual product, which is a smart tag for personal air pollution monitoring, which can monitor the carbon monoxide content around the user and send data to the smart phone via Bluetooth. This tag integrates Freevolt wireless charging technology, does not require additional power supply at all, and can continuously obtain power from the energy harvester.

Currently, Freevolt’s problems are mainly focused on: Can radio frequency signals in cities be taken at will? According to Drayson Technologies, there are currently no laws and regulations for extensive radio frequency signal acquisition in all countries in the world, so there should be no problems. In the future, Freevolt wireless charging technology will continue to develop, including the launch of more powerful collectors to charge mobile phones and smart home devices; at the same time, marketing will also cover the world, which is exciting.
