Design specifications and pricing for Pressure Sensing Transducers and
associated data recording device.
-- commercially available preferred
-- custom fabrication considered

We want to assess compliance for the use of a plastic body jacket in the
treatment of scoliosis; recommended usage will be 23 hours ON, 1 hour OFF,
with exceptions from time to time.

-- Pressure sensing will be needed only for on/off states, rather than the
measurement of actual pressure values.

-- Pressure sensors should NOT be adversely affected by temperature (i.e.,
an instrumented body jacket left in a hot automobile should not record wear
compliance during this time period.)

-- Two pressure sensors are anticipated, mounted flush with the interior
surface of the body jacket, most likely adjacent to the lateral rib cage on
each side of the body.

-- The data recorder should be of low profile (less than 3/8 inches), and
preferably of flexible or somewhat concave construction. It should be
capable of sampling the sensors once each hour, and storing the information
for a six month duration, although other sampling rates and durations will
be considered. The power requirements for the device should be met with an
integral power supply, such that the entire data recorder and power supply
are no larger than 6 in x 4 in x 3/8 in. The smaller, the better.

-- The sensors and data recorder will be fabricated into a body jacket by
an orthotist.

-- The recorder should be capable of downloading to an IBM compatible
personal computer; we expect this to occur once every six months (see

facilitate inclusion in the budget section of a grant application.
