As part of our participation in this year’s Semana de la Ciencia, we had the opportunity to share the fascinating world of electronics through a hands-on experiment: creating a homemade diode. This simple yet powerful demonstration captivated audiences, showing how science can be accessible and engaging for everyone.
The experiment involved constructing a diode using everyday materials—aluminum foil, copper wire, and a baking soda solution. By connecting the aluminum to a positive terminal, an oxidation process forms a thin insulating layer of alumina, blocking current to flow. This simple setup illustrates the fundamental principles of how diodes work, devices essential to modern electronics.
The experiment was not only a success but also a fantastic way to engage students, sparking curiosity and encouraging them to explore the field of electronics and materials science. We captured the process in a video to share this experience with a wider audience.
At the +QCHIP Chair, we’re committed to making science approachable and inspiring the next generation of innovators. Stay tuned as we continue to bring research to life through interactive demonstrations and collaborations.
