About this
project.

Hi! I'm a student at Institut auf dem Rosenberg in St. Gallen. This whole site is a school project — a concept I came up with for a small wooden bridge on our campus that produces its own electricity from people walking on it. Nothing here is built yet — it's an idea I designed, drew, and tried to make as realistic as I could.

Why

Why I made this.

I walk across campus every day, and I kept thinking: that's a lot of footsteps doing nothing. In some train stations in London and Tokyo, the floor tiles already turn footsteps into electricity. So I asked myself — could a school have something like that, but smaller and made of wood?

That question turned into this project. I'm not an engineer (yet 🙂) — most of the numbers are estimates I based on real products and papers I read. But it was a fun way to learn about timber construction, energy storage, and how a real architect puts a project together.

My school timeline

How I worked on it.

01
First idea
Week 1
Saw a video about kinetic floors. Sketched a wooden bridge in my notebook.
02
Research
Week 2–3
Read about glulam, piezo panels, LiFePO₄ batteries. Lots of Wikipedia + a few PDFs.
03
Site choice
Week 4
Picked the small ravine between Schlössli and the sciences wing.
04
Drawings
Week 5–6
Plan, section, energy diagram. First time using a CAD-style tool properly.
05
This website
Week 7–8
Built the site to present everything — including the live data demo.
06
Next
Show it to my teachers and (hopefully) the building committee.
Rough cost · my estimate

≈ CHF 1.4 M

Honestly, I'm not 100% sure about this number. I added up average prices I found online for similar small wooden footbridges and the kinetic tile technology. It could easily be ±30% off — I just wanted to show roughly where the money would go.

Concrete bases (abutments)
18%
Wooden beams + joinery
27%
Deck + railings
14%
Kinetic floor panels
21%
Battery + wiring
8%
LED lights + sensors
4%
Engineering help + assembly
8%
Thanks to

People who helped me.

A school project is never really one person. Big thanks to my teachers, classmates and family who answered my (many) questions.

Helped me sanity-check the watts
The STEM lab
Let me prototype a tiny piezo tile
Classmates
Walked over my sketches a hundred times

For the assignment + the campus
Honest part

What I'd still like to figure out.

Real watts per step

I used 5–8 W from product datasheets. I'd love to actually measure it on a small prototype.

Cold winters

St. Gallen gets snow. I need to think more about ice on the deck and how the panels behave at −10 °C.

Maintenance

Who fixes a panel when it breaks? I'd like to design a cover that any caretaker can pop open.

Cost

My number is a guess. I'd love to get a real quote from a Swiss timber workshop one day.

Thanks for reading

That's my project. Hope you liked it.

If you're a teacher, a classmate, or just someone curious — feel free to click through the other pages. The "Live data" page is my favourite: it pretends the bridge is already built and shows what it would be measuring right now.
