[time-nuts] Capacitive temperature sensing

One good general reference for capacitance micrometers is:

/Microdisplacement Transducers/ by P.H. Sydenham, Journal of Physics E, 
Scientific Instruments, Vol 5, p721-33, 1972. 
<Microdisplacement+Transducers%EF%BF%BD+by+P.H.+Sydenham,%20Journal%20of%20Physics%20E,%20Scientific%20Instruments,%20Vol%205,%20p721-33,+1972.>

It seems that capacitance micrometers can be 3 orders of magnitude more 
sensitive than I stated i.e. they can detect displacements of about 1E-14 m.
This compares well with interferometry which can detect displacements of 
around 1E-10 m.
