Aeternum is a company that was set up to help communities make better and more informed decisions about the quality of the air that people breathe. We provide the monitoring tools which inform communities about the air quality of a given area via our specially designed pollution sensors. We also provide a data analysis portal from which assessments regarding the severity of pollution levels can be made.
Aeternum’s outdoor sensors utilize unplugged, sustainable power sources such as solar which is used in our most current applications. However, the sensors will also run from mix of solar, wind and a patented RF energy harvesting method that uses rectenna technology to convert ambient energy to usable power. This is all designed to provide a simple solution for communities to mitigate the adverse effects of pollution and take steps to improve air quality in an informed way.
We believe the current technology and systems in place to monitor pollution are outdated and inadequate. By providing a complete end-to-end solution, connected by secure wireless networks, we hope to empower communities to make the changes necessary to improve people’s health.
How did you come up with the idea for the company?
The original idea behind Aeternum came from our work completed alongside the University of Liverpool, in which we worked to research RF energy harvesting technology and its potential uses in commercial outdoor sensors. Following the successful development of this now patented technology, we worked with the University to deploy a city-wide air quality sensor network across Liverpool.
This R&D process revealed two things about the current ecosystem of pollution monitoring. Firstly, current sensor technology is often very costly and relies on a complex and labor-intensive process. Through solar energy, we have developed sensors that can be powered independently, without connection to the mains or constant battery maintenance. The company name Aeternum, meaning “forever” in Latin, was chosen because the development of this technology allows these sensors, in theory, to be powered forever. Second, the DEFRA pollution sensor ecosystem set up across the country only provides a snapshot of the air quality in each specific location.
The DEFRA sensors are typically very large and therefore fixed to a given area. However, as with many things, air quality and pollution levels can vary massively and change depending on a variety of factors both over time, but also specific to any given area. Our aim in starting Aeternum was to come up with a way of being able to deploy accurate air quality monitoring stations that are also mobile.
Our sensors can be moved quickly and easily to provide measurements across a wider area, and to enable a more accurate understanding of those factors which impact air quality. Only from here can robust policy responses be built.

How has the company evolved during the pandemic?
Aeternum as a company has really taken off during the pandemic. Whilst our research in cooperation with University of Liverpool began back in 2017, we have made major developments in the production of our innovative sensors, and with partnerships, working alongside community organisations. In many ways, the pandemic has given people a greater sense of stillness in the places where they reside.
For this reason, more communities have become aware of air quality and the adverse effects of pollution. The spread of COVID-19 has also brought greater attention to respiratory illnesses, highlighting the need for clean and safe air quality where we live and breathe. With the urgency of the climate crisis ever-increasing, and our relationship to the urban environments with which we live currently in flux, Aeternum has found its place empowering communities to better understand their lived environment.
What can we hope to see from Aeternum in the future?
The World Health Organisation (WHO) has reported that more than 80% of people living in urban areas that monitor air pollution are exposed to air quality levels that exceed its guideline limits. Ironically enough, data from Aeternum’s sensors recently showed that the upsurge in city traffic and congestion during COP26 led to Nitrogen Dioxide levels that were to 93% higher than WHO Air Quality Guidelines.
This is not to say to undermine the incredible importance of the conference. It is merely to say that an awareness of air pollution levels, and the impact of different community-wide events, is important from a public health perspective. This is something that can only be achieved by broader data monitoring systems.
In this way, our vision for Aeternum is to empower communities through data. Pollution monitoring should be standard for any area wishing to improve air quality and ultimately public health. We hope to continue to partner with community organisations to make this a reality. We have already partnered with Class of Your Own Limited (COYO), an award-winning consultancy specialising in STEM education for the digitally built environment.
Through this partnership, we were able to monitor the M8 motorway during COP26 and provide an accurate picture of the changes in pollution. We hope to pursue further initiatives of this sort in the future, widening the reach of pollution monitoring, and the insights it can provide, throughout the UK, and beyond.
