## Summary

Reddit users discuss a paper on a tactile sensor based on mechanochromism, whose authors claim the sensor can capture pressure at fingerprint-level resolution and generate color pressure maps. The poster questions whether robots really need such high tactile resolution, and admits they are not a materials specialist and are unsure how the material actually works.
