These fabrics were made of volcanic basalt, which is the most common rock on Mars. This project began as a design challenge when my friend, J.R. Skok (a planetary geologist at the SETI Institute), provided me a bunch of basaltic fabrics to make something fashionable.
While I was trying to master constructions using these fabrics, I couldn't help but thinking when and why we would ever want to visit Mars. Apart from our scientific curiosity and exploration, could it be caused by in-habitability of the Earth environment? This dress embeds an optical dust sensor and a temperature sensor which gives warning about air pollution and global warming.
I used A3 for dust sensor analogue pin to avoid sharing pins with other sensors on Adafruit Circuit Playground Express. The diagrams are from https://www.instructables.com/id/How-to-Interface-With-Optical-Dust-Sensor/
