Similar to the "temperature-sensitive
paint" idea (something that I never
added, wish I had), a paint whose
color changes as pressure is applied
to it.
Seems to me that it might be an
interesting tool for use in a wind
tunnel, to test aerodynamics. It'd
be easy to find the yellow 'trouble
spots'
on a red auto body, after all...

Would it be necessary to attach psi readouts on the inside of the vehicle body panels? That would negate the need for paint. However, if the prototype were clay or wood, paint would be good-therefore would the paint be need to be compliant with any external sensor devices? |

There is something similar to this that I saw a long time ago on 'Beyond 2000' (a show whos name I hope they changed if its still on somewhere), it was paint used to detect inpacts on planes, eg birds and stuff. More like 'pressure spike' or 'impact' sensitive paint. :) |

Quite baked, and in fact widely used in wind tunnels. Follow centauri's link to my link. |
