Brief: Create a prototype of anything, using programming and electronics basics.
Approach: I created a scarf that changes shape based on the weather around you, stemming from my interest in wearable technology. I dove deep into prototyping and material exploration and successfully programmed my scarf to expand and contract based on readings taken from my ambient temperature sensor.
Learnings: Arduino, Processing, Coding, Prototyping, Sensors, Knitting
Project length: 3 weeks
What is it?
Smart Scarf changes shape depending on outside temperature, always keeping your body comfortable based on the weather around you.
After brainstorming ideas, my "hot and cold scarf" was the most exciting and innovative.
I began prototyping by knitting several mini scarfs and running shape memory alloy through the different prototypes. I played with different levels of current running through the shape memory alloy. I troubleshot many forms of my code to get the scarf to sense temperature and then run current through the alloy.
In order for the smart scarf to be "smart" it needed to sense outside temperature. I mapped the desired temperature threshold (each user can adjust theirs based on personal preference) and once the scarf reached a certain temperature, it expanded or contracted.
Smart Scarf Prototyping
This final prototype consists of a knit mini scarf, woven shape memory alloy, and silver clasps to keep the alloy in place when expanding and contracting.
