Today we continued making our own pressure sensors, which control the brightness of an LED by how hard the sensor is squeezed. Once we finished building the sensor circuits, we attached them to foam stress toys to create our own pressure sensing, light up stress toys.
We also learned that circuits don't always work on the first try, and how to "debug" them. This is an important part of the process! In the words of Thomas Edison: "I didn’t fail 1,000 times. The light bulb was an invention with 1,000 steps."
Today we met the amazing Michelle Mellenthin, a biomedical engineer and post-doctorate researcher. We learned about her experiences with Engineers without Borders and her current research on technology that helps damaged lungs function properly. We also talked about the use of sensors in biomedical engineering and started making our own pressure sensors!
We will finish making our sensors at the next meeting on Dec. 12, and continue our exploration of electronic circuits by making festive LED ornaments.
