We Do Love Nonlinear Science - Stories from the front line of Functionality Through Nonlinearity 2025

Last week, I had the chance to take part in something truly special – Functionality Through Nonlinearity (FTN 2025), a free and open conference hosted at King’s College London for anyone passionate about nonlinear science – the complex study of systems where a change output isn’t the same as a change in input.

Organised by Dr Antonio E. Forte (King’s), Dr Benjamin Gorissen (KU Leuven), and Dr David Mélançon (Polytechnique Montréal), the event brought together a vibrant mix of scientists exploring what happens when flexible materials bend, buckle, stretch, and snap to perform useful work.

As a postdoc in the Reconfigurable and Adaptive Designs Lab (RAD) Lab here at King’s, I was part of the team supporting the event. However, I also got to immerse myself in the science, the community, and the creativity that this meeting of minds brought together It was an energising, brain-stretching, and surprisingly playful dive into the world of soft matter and smart structures, materials that detect changes in the environment and react to them.

So, what is Functionality Through Nonlinearity? At its heart, it's about designing function through structure and material response. Researchers here are building soft robots, wearable tech, adaptive materials, and even artificial organs –not with rigid parts or electronics, but with carefully shaped flexible materials that move and compute through their very form. These structures ditch the traditional constraints of a built-in controller in favour of a body that can operate independently, embracing greater contextual awareness and dexterity.

King’s got involved through Dr Forte’s RAD Lab, one of the conference’s co-organisers. The aim wasn’t just to showcase research, but to build a community –a place where engineers, physicists, designers, and computer scientists could come together to explore new ideas in soft robotics, mechanical computing, and responsive materials.

Over two packed days, the conference featured 22 inspiring talks. On day one, we kicked off with 12 sessions led by world-renowned researchers. One highlight for me was Dr P.T. Brun (KU Leuven) introducing “bucklebots” –tiny brainless robots that move by buckling their soft bodies, showing how structure without the need for controllers can create intelligent behaviour. Another standout was Dr Damiano Pasini (McGill), who showed how combining japanese origami and kirigami principles allows flat shapes to morph into complex forms –like turning a cube into a sphere –using programmed folding.

What came next was a real left turn (even if I helped plan it!) a nonlinear treasure hunt. We broke into eight teams to solve puzzles linked to some of London’s most famous sights. Cracking through the case led us back to the final answer, and the thing which brought us all together in the first place: “We Do Love Nonlinear Science.” It was intense, fun, and the perfect way to get people from different backgrounds talking.

Day two featured another 10 talks and a buzzing poster session with 60 presenters from across the globe, including Harvard University, the University of Oxford, National University Singapore, TU Delft and more. Researchers didn’t just show charts; they also brought working prototypes: soft grippers, bistable valves, responsive fabrics, and 3D-printed components that change shape. These weren’t just ideas – they were tangible, moving, and sometimes crawling!

Highlights included:

  • Soft robots that move without motors using snap-through instability
  • Multi-material 3D printing for valves, sensors, and tendons
  • Kirigami-inspired sheets that fold into programmable 3D structures
  • Mechanical computing using elastic switches
  • Wearable textiles that respond to touch and pressure
  • Hydraulic tentacles and self-regulating artificial hearts

All of it points toward a future where machines are soft, adaptable, and capable of “thinking” through their bodies.

FTN 2025 wasn’t just about showcasing research –it was about creating real connections. Whether bonding over treasure hunts, poster chats, or lively debates after talks, we built a welcoming, interdisciplinary space that sparked new ideas.

For me, and for King’s ,it wasn’t just a conference. It was a glimpse into the collaborative future of soft robotics, nonlinear materials, and embodied intelligence.
