Mechano-chromization



2021   Material Design


What if we sense everyday force distribution through color gradation?



Polydiacetylene; a mechano-sensitive polymer that changes its color upon external stimuli(light, heat, and friction) was explored as a potential application for visualizing everyday force distribution.

Based on the iterative trial and errors regarding deposition materials and methods, it was observed to deposit and function effectively on cellulose-derived materials. As a final output, three application possibilities were explored along with the Proof of Concept samples.

Sugihara Lab. is conducting research on the correlation between the color change of polymers and the amount of shear force at the molecular level. Combined with this experimental project, it is expected to lead to further applications as an everyday human-scale force maker.
