Abstract

This research presents an investigation on flat textile pressure sensor characteristics that are advantageous for
the use in the surgical environment to monitor the development of pressure injuries (PIs). Eight custom
prototypes of 4x4 textile pressure matrices are subjected to sensor error testing to evaluate the sensor output
differences on foam vs. no foam. The pressure matrices are subjected to sensor error tested using a mechanical
tester set up in a compression format (Fig 3.) where the voltage output was monitored. Each sensor was
analysed for sensitivity, span and non-linearity. The findings show that for the use in the surgical environment
on foam surfaces, prototypes 2 and 3 had superior performance results, with non-linearity error decreasing and
sensitivity increasing on foam. Both prototypes exhibit properties that are more suited for the surgical
environment, specifically on foam surfaces, and warrant further prototype development.
