Dear Biomch-L members,

I would like to thank all of the Biomch-L subscribers who
responded to my question for information on an in-shoe (wireless)
pressure system which can measure for a long period: 8-10 hours.

I suggest that you contact Cleveland Medical Devices as I think
they have just the product you are looking for.

Our lab has been working on a device that can save pressure,
temperature, and humidity information for extended periods of time.
Our current device records for about 4 hours, but the next version
will easily go 12-16 hours. Unfortunately it is not commercially
available yet. We have two manuscripts that are in the review
process in a PT journal and in IEEE. If you can search
abstracts, we have a published abstract about the shoe from the
BMES/EMBS Conference (1999 in Atlanta). The first author is
Richter, E.

To cut the story short, the answer is NO. Pedar is your best bet.
I am at the moment finalizing a Review Article on Foot Pressure
Systems and I can confirm that, to my knowledge, there is no
system available to record 8 to 10 hours of continuous
measurement for the simple fact that there has not been a need for
it until now.

On a related issue myself and colleagues in the National Centre for
Bio-Sensors are planning on developing a gait pressure sensor
system. I have been assured by the sensors group that should
there be a need their is no problem in developing pressure reading
in-soles to measure data over 8-10 hours, even if no one has
developed such a system to date.

I have just finished a review article for physiological measurement in
ambulatory subjects. It will hopefully be published by the IOP in
Physiological Measurement soon. It covers the technology of data
logging devices not telemeterised, which can give you more
flexibility. There are systems by Vitaport and Onset which have
large storage capacities which may allow collection for 10hrs. If
you require more info I may be able to forward you a copy of the

From:"Holthe, Michael SBCCOM(N)"

you may want to check with Biomedical Monitoring Ltd. They can
custom-make data loggers that can collect quite a bit of data and
store it until the time you download it to your PC. Whether or not
you are storing an analogue or digital signal is the only question
that may pose some problems, but worth a check.

From:Peter Seitz

the pedar mobile can measure up to 1 hour scanning with 10.000
sensors per second.
That means if you want to monitor both feet with 99 sensors each
and use a 40 MB flashcard (very special one) .
If you scan slower (1000 sensors per second) and if you are fine
with for example 25 sensors each insole you can monitor 40 hours.
All selectable by software.

Peter Seitz
From: Frank Edwards

We are currently developing dynamic sensing systems for foot
pressure monitoring.
Our telemetry system for dynamic joint monitoring could certainly
give you the time scales you mention.
If you would like to send me more details of your requirements I
would be only too pleased to see if our technology will meet them.
