Berlin. On the fabric, researchers have placed passive matrices of compact RGB LED packages. The<br />
pixelated luminaries with relatively large distance between RGB pixels have been embedded in<br />
everyday objects like cushions and floor mats.<br />
The photonic textile can also be made interactive by incorporating sensors, like pressure or orientation<br />
sensors, and communication devices into it.<br />

The picture shows the photonic textile. As the fabric covering the tiny light source naturally diffuses<br />
light, each pixel seems bigger than it actually is [167].<br />

2.3.5.1 Research projects and products<br />
In the technical textile sector, optical fibres are often used as sensors to exploit the Bragg Effect.<br />
At the Hong Kong Polytechnic University, a research group has developed several applications using<br />
optical fibres to measure strain and temperature in composite structures [168, 169, 170, 171]. Fibre<br />
optic Bragg grating sensors are attracting considerable interest for other sensing applications, like<br />
pressure, chemicals and biological factors [172].There is a great interest in the multiplexed sensing of<br />
smart structures and materials, particularly for the real-time evaluation of physical parameters at<br />
critical monitoring points. Most of the sensing applications of Fibre Bragg Grating (FBG) sensors focus<br />
on their reflection spectra, which depend on the relation between the Bragg wavelength and their<br />
physical quantities.<br />
Further, a research group at the University of Maribor is working on fibre-optic chemical sensors. In<br />
this case, optical fibres act as remote sensors and can detect chemical contaminants. Light is<br />
