YANG YANG WELCH

I spent summer 2011, working as a contractor at Microsoft Research. I researched e-textiles and helped to design & prototyped fabric electronics that work as both a non-emissive thermochromic display and as input sensors.

The fabric display is realized through a resistive heating grid made of conductive fabric rows & columns sandwiching a resistive fabric layer under a thermochromic fabric layer.

The fabric input is realized through a similar grid of conductive rows and columns sandwiching a piezoresistive fabric layer.

The final sensor protype took the form of a wearable fabric sleeve capable of stroke-recognition and wirelessly sending ghostly messages to the fabric display.
