Hi All,

I wish to commend Dr Mansfield for his summary posting on the pressure
sensing mats.
If possible, I would like for Dr Mansfield (or others) to comment on or to
site an abstract/article/paper publication as to how it was determined that
a sheet which changes color with pressure is more far more precise than
other systems that quantify pressure from active sensors. I refer to his
comment sited just below.

"_Pressurex_
http://www.sensorprod.com
This is a one use system that allows for pressure measurements to be
recorded on a paper sheet. The sheet changes colour with pressure and is
then scanned using a special scanner. It is far more precise than the
systems above, but is not real time."

Kind regards,

Norman
Norman Murphy, Ph.D.

Greetings!

Thanks to everyone who replied to my email of a couple of weeks ago.
Following is a list or recommendations and the original post (detail
depends on how much information I have been able to obtain on the systems):

_Tekscan_
http:\\www.tekscan.com
Offer industrial and medical systems with a variety of sensor array shapes.
Sensors are built into a thin plastic sheet. Web site gives detailed
information about the systems and technical information. There are
possibly issues with creasing of the sensor array giving false readings.

_Novel GMBH_
http://www.novel.de
Offer a range of medical systems named 'emed', 'pedar' and 'pliance'.
Sensor arrays appear to be built into a flexible mat which is thicker than
Tekscan, but are not so prone to creasing. Web site is informative,
although far more sales focussed that technically focussed.

_RS-Scan_
http://www.rsscan.com
A small Belgian company offering similar products to Novel, at (according
to the salesman!) lower cost. The web site is less informative than the
above companies.

_Pressurex_
http://www.sensorprod.com
This is a one use system that allows for pressure measurements to be
recorded on a paper sheet. The sheet changes colour with pressure and is
then scanned using a special scanner. It is far more precise than the
systems above, but is not real time.

_Xsensor_
http://www.crownthera.com
Appears to be a budget version of tekscan, but with a lower specification.
Most common application is seat fitting (e.g. wheelchairs).

located in Atlanta,

_FSA pads_

____Original post_____
I am looking into pressure sensing mats for using on soft seats. I am
familiar with Tekscan, but am unaware of competitors. Does anyone have any
information or contacts?
