A microgenerator using vibrations as a power source has been developed

    Employees of the University of Southampton (Great Britain) developed a generator that collects electromagnetic energy of vibrations. According to the developers, the new microgenerator can be used to provide energy to wireless sensors and even medical implants.


    The generator is able to convert up to 30% of the kinetic energy of the environment into electricity. It can provide various kinds of devices with reduced power consumption when alternative power sources (for example, solar energy) are unavailable.

    A microgenerator collects energy using the swinging of several magnets mounted on an arm no larger than a millimeter in size. Without going into scientific details, the principle of operation of the generator can be described as follows. "Responding" to vibration, the bracket begins to swing up and down. The magnets attached to it also begin to move, and the magnetic field they create is used to produce electrical energy. British scientists not without pride declare that their development is the most effective of all existing microgenerators.

    When testing the generator in laboratory conditions, taking into account the vibrations generated by such a structure as a bridge, the device was able to generate 46 microwatts of electricity. According to Steve Bibi (the project manager and the team that developed the microgenerator), this energy is enough to power small devices, such as sensors. Of course, such a small amount of energy is not enough to ensure the operation of the phone or MP3 player. But in the near future, the use of a microgenerator is possible in medical implants, such as, for example, an electronic stimulator of the heart. In this case, the heartbeat will be the heartbeat. Great symbiosis. The heart “feeds” the generator, the generator ensures its operation ...
