Abstract:

This paper presents a method of screen-printing a conductive carbon nanotube printing paste onto textile substrates to prepare textronic strain sensors for measuring breathing rate. Screen-printed sensors can be integrated with garments after construction and do not require significant modification of the construction process. Personalisation of the garment is used to optimize sensor placement for improved measurement accuracy. Changes in the electrical resistance of the sensor as a result of changes in strain are detected and used to determine the breathing rate.
