This article will present a prototype of a textronics system for monitoring one of the most vital human signals, the frequency of breathing. Here, the authors present optical fibre techniques in textile engineering, as great methods to transmit measured signals inside fibrous structures. Good elastic properties and small dimensions of optical fibres are attributes which make these fibres particularl useful for the designed textronic applications. The authors focused on the design and description of a non-invasive system of health monitoring, which extends traditional clothing functions, and at the same creates a modern textronic product. The monitoring system is composed of two optical waveguides- the sender and receiver, a sensing head with textile spring and electronic system. The whole textronics system is an autonomic measuring device. The authors also present examples of a breathing rhythm recorded for different persons of different ages. The Breath Frequency Sensor (BFS) may be used in many applications, for example the uniformed services or medical personal monitoring clothing, which allows a normal life for patients as monitoring can take place without the need to stay in hospital all the time.
