ideas for knowledge sharing presentation?

At work I have to organize a presentation. The idea is to share knowledge among the team and the topic can be anything tech-related. I'm on a small design/front-end dev team while the rest of the audience would be app developers and data engineers. I would like to choose a topic in the realm of design that would be relevant, interesting and useful to people who are normally working on the more technical side of things?

Any brilliant suggestions?
