hi,
your problem is quite simple. try
http://www.vishay.com/brands/measurements_group/strain_gages/tclass/gages/indexes/cir_dia.htm
the diaphragm strain guages can be used to transduce applied pressure. there is also lots of do-it-yourself kind of stuff in the website.
Can any one provide me information that might be useful in construction of a pressure sensor array. The array needs to be placed over the index finger to measure pressure due to holding of needle holder while doing surgery.
I guess this possibly can be done using MEMS technology. Any...
