Concept for direct integration of electronic circuits and sensors on textiles using inkjet printing.

The paper presents a new concept of integration of electronics and sensors directly on textiles by additive manufacturing namely inkjet printing and dispensing. A breath rate sensor, accelerometer and pulse sensor were integrated on a stretchable fabric with their conditioning circuit and their performance was evaluated using a tensile stretching machine to mimic human respiration. The device enables wirelessly data transfer to a base station for futher data analysis.
