Electrochromic Visor Aids Motorcyclists

Posted by michael on Friday September 5, 2003 @05:00AM from the night-rider dept.

opticsorg writes "A team from Uppsala University and the firm Chromogenics Sweden AB have developed a flexible electrochromic foil and integrated it into the visor of a motorcycle helmet. The result is a visor that the rider can electronically switch between dark and transparent states. Applying a voltage of about 1V to the initially transparent visor causes it to darken in a matter of seconds. When the voltage is turned off, the visor keeps its properties, while applying a reverse voltage makes it revert to its natural lightly tinted state."

And for all the people who will post about "I want this on my car" - no, you don't.

Aww, c'mon, I've been waiting 20 years to say, "KITT, darken windows".

The venetians have had something to do that for years.
