Question: I am presently involved in research involving wheelchair seat pressure for patients with chronic neurodisability. I would be obliged if you could provide me with information on companies manufacturing pressure transducers for monitoring wheelchair seat pressure. ~R.Purkayastha

Answer: Have you consulted The Wheelchair Site's page on wheelchair cushions & backrests under wheelchair accessories?

After doing an Internet search I've uncovered an informative PDF article entitled 'Improved Wheelchair Seating' published by the Wheeled Mobility Research Center at the University of Pittsburgh (rercwm.pitt.edu) I hope this helps with your research.

We have also learned of research in the same field being conducted by the mechanical engineering department at the State University of New York, though I don't have any further details. Check with SUNY to see if they can help
