Sound/vibration sensor system for E.coli --Erwinswinnen 09:25, 8 June 2011 (CDT)

--> Jonas: presence of mechanosensors MscL/MscS in E.coli

--> Koen: use of human hair cells? Is it recommended to work with E.coli? We can also use human hair cells, then we could make a direct sound sensor in stead of a pressure sensor.

Good websites with the basics of hearing: http://www.ks.uiuc.edu/Research/hearing/ and http://www.beyonddiscovery.org/content/view.page.asp?I=259

In the ear the crucial point is converting the mechanical stimulation of the hair cells into a membrane electric potential which leads to neural signalling. Maybe it is possible to visualize this electic potential and make a correlation between the frequency of the sound and the colour we use. For example a blue colour is generated when the frequency of the sound is X MHz. Another advantage of working with human hair cells is having much more previous research literature. Now we only need the time to explore it ... ;-)
