Hi Gabriela,

we have been working on performing temperature meaurements using patterned
platinum resistors mounted as lids or supports for silicon microreactor
cavities.
We have also looked at using very small thermocouples (hair-like and quite
fiddly
to use) and non-contact infra-red thermocouples (in practice the least
successful
mode).  If you would like some more information about any of  these, let me
know.
We could also probably send you some of the platinum resistors (they are
fabricated on pyrex) or if you sent over some of your devices, we could try and
put together some configuration that you could use.

All the best,

Dr. Helen Berney.
