We are a team of four microengineering students from EPFL, the Swiss Federal Institute of Technology in Lausanne, Switzerland.
We completed our Bachelor’s degree in 2016 and since then, Micha and Ben went on with their Master’s studies, Chloe took a year off exploring the world and Yoann settled on a scientific base in Antarctica.

We developed BeMap to empower people by giving them a tool to measure their exposure to atmospheric pollutants. For many city residents, air pollution is an important health concern, but remains difficult to identify as it often remains invisible.

We believe that people can and should be able to control their exposure to air pollution. We also believe that everyone can contribute, not only people with degrees and technical expertise. This is why we open-sourced BeMap : users can modify and customise their devices, and everyone can access the crowd-sourced data, even with modest technological knowledge.

Team Members

Micha Burger


Resourceful, Micha has a good organisational mindset and is excellent at marketing. He developed BeMap’s computer software that makes beautiful maps out of air pollution data and uploads them to the web server.

100% Swiss, Micha like driving trucks and trekking in the mountains by day and programs in Java at night.


Chloe Dickson


Chloe is a passionate STEM and robotics educator and is active in Women Empowerment networks. For BeMap, she designs the 3D-printed housing and manages our collaborations and external communications.

Chloe was a track cycling and mountain biking champion and is crazy about robots, ukulele and backpacking.

Benjamin Bonnal


Always aware of new hacks, Benjamin like to find solutions to problems. In BeMap, he took part in the electronic design, selected existing open-sourced projects and adapted them to our needs.

Great musician, Benjamin plays the trombone and the guitar. When the weather allows it he pilots his homemade drones.


Yoann Lapijover


Yoann is curious, highly skilled, and always involved in thousands of projects at the same time. For BeMap he writes the embedded software and also works on the electronics design.

Always available for a drink, he is a sailor and does an amazing PCB routing job. He is currently settled in the Kerguelen islands in Antarctica for a 14-months long scientific mission.



Robopoly : EPFL’s robotics association and makerspace


As our prototypes are currently home-made, we need the good tools and places to make BeMap become reality. Fortunately, we have Robopoly, the robotics association of EPFL. The have the exact set of tools needed to complete our project : soldering iron, lab magnifier, 3D printer, etc… BeMap would never have existed without their help.

Open source

Everything in the beMap project is open-source, from the device hardware to the data analysing software. A big part of our work is based on other open-source projects, by reusing the work of others we avoid “reinventing the wheel” and integrated precious knowledge. We believe that making open-source hardware/software and research in general is important, and we are convinced that the future of technology resides in the power of individuals that contribute step by step to achieve more collectively than any individual could ever do alone.


In 2014, after failing some of our second year exams, we were left with some spare time and a challenge: develop a project using sensors for the Swiss iCan contest and beat the Zurich team to win a trip to Alaska. And that’s exactly what we did.

In April 2015, we won the Swiss iCan contest and were sent off to represent Switzerland in the world finals in Anchorage, where we were awarded the second prize.

Early 2016, we received an email from Swissnex Brazil inviting us to organise Mapping Parties in Rio de Janeiro and São Paulo. We flew over in May for a scaled-up testing of our prototypes in collaboration with cycle activists, mobility and health specialists.

Currently, Micha is actively working on BeMap as a semester project, focusing on bringing BeMap to the cloud with LoRa wireless communication. There are also discussions of building a BeMap community in Colombia!
