Hello all,
I know that you have all been waiting impatiently for the compilation of information on miniature force transducers and strain gauges that I posted a while back. Well, here is that information in condensed form.
Original Question: Are there commercially available force transducers/strain gauges/buckle transducers that can be used in non-implanted surgical procedure that can tolerate a maximum load of 10kg with resolutions of 0.1-0.2kg?
The primary response was to contact one of three companies (listed below) for the possibility of purchasing an already available device or having a device customized for my needs. The secondary response was to design my own using technical articles previously published in the biomechnical literature.
The commerically available option turned up one company that has a reasonably similar device. However, the other two companies did say that such a device would be manufactured at some 'X' cost. In each case, the device would cost around $5,000 for direct purchase or customization.
The companies that I was directed to contact are listed below.
NK Biotechincal Corporation www.nkb.com
MicroStrain Corporation www.microstrain.com
AMTI www.amtiweb.com
The option to build my own device was well referenced, particularly by the work of Dr. John Holden. This is an attractive option; but there are time and effort considerations if pursued.
Thus, I remain at step one, although I now have a wealth of information on the enginering design of such devices and the types and costs of those that are already available. I truly appreciate the time and effort that each contributor offered in solving my dilemna. They are listed below.
