     1This is a project to develop an apparatus to measure the finger grip strength of monkeys in the laboratory of Doug Rosene at the BUMC. 
     2The idea is to build a device similar to that described in
     3[http://ohm.bu.edu/~hazen/RoseneLab/Ohio%20State%20Univ%20-%20Pinch%20Test.pdf this article]
     4
     5An original proposal provided in May, 2009 included the following brief description which is still valid:
     6
     7{{{
     8 Two grip measurement devices (for the left and right hands of the subject) will be equipped with
     9 aluminum tongs attached to strain-gauge type force sensors, and read out using custom
     10 electronics housed in a small operator console. The console will provide an LCD display and
     11 operator controls. The peak force exerted by the subject during a trial period will be displayed,
     12 along with the date and time. A few previous measurements may be stored in memory and
     13 recalled to the display. A simple computer interface will be provided for optional readout and
     14 storage of measurements. The entire apparatus will be housed in a Plexiglas box with two
     15 openings; one for each hand of the subject to reach the aluminum tongs (pinch mechanism)
     16
     17}}}
     18This description is reasonably accurate, except that for cost saving reasons we propose
     19to omit the date/time display and computer interface unless the additional cost is negligible.

     21Some further details:
     22
     23* Two sensors, right and left will be provided.  They will be standard industrial strain gauges
     24similar to [http://ohm.bu.edu/~hazen/RoseneLab/207.pdf this one]
     25* A simple display box which displays the maximum force in Newtons, a left/right switch, and a reset button will be provided.
     26* A calibration method will be provided to adjust the display output to read accurately in newtons.
