Join us for this hybrid event! Register until November 6!

Participate in-person and benefit from the networking, or join online.

Please note that, as the event will take place across three locations (Lisbon, Barcelona and Wroclaw), two time zones will apply: Lisbon time (WEST/WET) and Europe/Warsaw time (CEST). All times in the schedule are listed in Europe/Warsaw.  The event in Lisbon will start on Thursday, November 19, 2026 at 08:30 (Lisbon time), which corresponds to 09:30 (Europe/Warsaw), and will end on Friday, May 22, 2026 at 18:30 (Lisbon time), corresponding to 19:30 (Europe/Warsaw).

Cities today face increasingly complex and interconnected challenges at the intersection of climate transition, health, environment, mobility, social cohesion and quality of life. Climate pressures are increasingly affecting citizens’ wellbeing, with infrastructure not conceived to be resilient to climate transition, and while the largest shares of the emissions come from the private uses such as personal car mobility and housing heating. These challenges are particularly relevant for intermediate cities, which need solutions that are innovative and scientifically grounded, while remaining affordable, scalable and adapted to local contexts and resources.

This Tri-City Hackathon responds to these challenges by creating a space for experimentation, collaboration and applied innovation. It explores how biotechnology, life sciences, health innovation, digital technologies, engineering and citizen-centred approaches can help transform the low-carbon transition into an opportunity to create cities that are healthier, more comfortable and more resilient. From biosensors and diagnostics to biomaterials, nutrition, environmental biotechnology and digital health, the Hackathon invites participants to develop practical solutions that connect human health, environmental health and the future of urban living.

This hackathon is a two-day, international innovation challenge under UNITE! Widening project, and is organised by:

• Universidade de Lisboa (ULisboa)
• Universitat Politècnica de Catalunya · BarcelonaTECH (UPC)
• Wrocław University of Science and Technology (WroclawTech)

This 48-hour hybrid innovation will take place on November 19-20 and will bring together students, researchers, professionals and engaged citizens to rethink public infrastructures and technology uses as a living, shared and regenerative commons, to design and prototype solutions that advance more sustainable, inclusive, and human-comfort decarbonised cities.

It combines seamlessly key actors from the quadruple helix, namely: Academia (ULisboa, UPC and WroclawTech), municipalities (Viladecans-Ofinina del Futur), society (individuals participating) and business ecosystem (Entrepreneurship offices and entities of Can Calderón, Lispolis and ARAW).

Why Participate?

• Go international: Work in a unique hybrid environment connecting students from ULisboa (Lisbon), UPC (Barcelona) and WroclawTech (Wrocław).
• Make real-world impact: Collaborate directly with “Problem Framers”—experts who are looking for real solutions to implement.
• Access multidisciplinary networks: Rub shoulders with researchers, architects, coders, and urban planners from across Europe.
• Accelerate your skills: Sharpen your skills in rapid prototyping, data-informed design, and high-stakes pitching
