Micro-generators generate electricity from environmental vibrations

UK scientists have successfully created a micro-generator that generates electricity by oscillating around it.

As a result of research by scientists at the University of Southampton (UK), the generator was created to power active devices at locations where the replacement of batteries is very difficult.

Initially, it will be used to power the wireless sensors set in the production line. The author of this generator says that their technology is capable of generating up to ten times more power than similar devices.

Although the amount of electricity it produces is only a few microwatts, according to Dr Steve Beeby, the head of the research team, is enough to power sensors mounted on production lines in factories. .

"The big advantage of wireless sensor systems is that when removing wires and batteries, people can put sensors in places where they could not be placed before."

The use of these micro-generators can also help with the use of sensors in large numbers as there is no longer a need for continuous testing to replace the batteries.

Dr. Beeby said that although the original purpose of the generator was for compressors, in the future it could also be used in self-contained transplant medical devices. For example, pacemakers.

According to scientists, if the generator is used in a pacemaker, the heartbeat of the human heart is strong enough to keep the magnet in the oscillator. In addition, the new product will also be used to power sensors mounted on road bridges and railroads to monitor the condition of these buildings.
