Aeternum’s sensors are powered by technologies that capture and make use of abundant ambient energy (energy harvesting). This includes converting electromagnetic (EM) energy from mobile, radio transmitters and other wireless communication systems as well as energy from solar and wind based technologies. Our “unplugged” power solution allows you to place micro sensors anywhere while collecting and reporting information over long distances.
We use this converted energy to either top up a small battery or to power a device directly. By taking this approach, we are able to reduce the number of field visits (truck rolls) including the need to manually intervene or support whilst at the same time maintaining a continuous data stream that’s open to our dashboard and analytics work space.
Aeternum’s patented energy harvesting technology at work: Our rectifying antennas harvest small amounts of power from radio waves. This energy is then transformed using a process called DC-to-DC conversion which steps up voltage, whilst stepping down current. It is a form of switched mode power supply which converts electrical power efficiently using components that can fit on a human fingernail. It is this technology when combined with other typical energy harvesting technologies (for example, wind and solar) that allows Aeternum to offer unique, small footprint, unplugged solutions.
