what future technologies could be used in head protection?

[graed8]

Hi, my name's Graham, currently studying product design at uni. I'm trying to gather as much info as possible on the subject of head protection for cyclists, in the future. I've been looking at Aerogel's and ferrofluids as possibly providing protection in the future, but am not too sure on their possible applications, or whether they could provide protection at all. Are there any other new materials that have specific energy absorption properties that I could have over looked?

 

If there's any links that you could provide, and personal opinions about head protection in the future, it'd be more than welcome.

 

thanks for your time guys
