  • Woven Temperature and Humidity Sensors on Flexible Plastic Substrates for E-Textile Applications

    IEEE Sensors Journal

    Abstract—In this paper, a woven textile containing temperature and humidity sensors realized on flexible, plastic stripes is presented. The authors introduce two different sensors fabrication techniques; the first one consists of a conventional photolithography patterning technique, the second one, namely inkjet-printing, is here presented as an effective, low-cost alternative. In both cases, we obtain temperature and humidity sensors which can be easily integrated within a fabric by using a…

    Abstract—In this paper, a woven textile containing temperature and humidity sensors realized on flexible, plastic stripes is presented. The authors introduce two different sensors fabrication techniques; the first one consists of a conventional photolithography patterning technique, the second one, namely inkjet-printing, is here presented as an effective, low-cost alternative. In both cases, we obtain temperature and humidity sensors which can be easily integrated within a fabric by using a conventional weaving machine. All the sensors are fully characterized and the performances obtained with the two different fabrication techniques are compared and discussed,
    pointing out advantages and drawbacks resulting from each fabrication technique. The bending tests performed on these sensors show that they can be successfully woven without being damaged. A demonstrator, consisting of a mechanical support for the e-textile, a read-out electronic circuit and a graphical PC interface to monitor the acquisition of humidity and temperature values, is also presented and described. This study opens an avenue for real integration between printed electronics and traditional textile technology and materials. Printing techniques
    may be successfully used for the fabrication of e-textile devices paving the way for the production of large area polymeric stripes thus enabling new applications that, at the moment, cannot be
    developed with the standard lithography methods.

    The present invention discloses a smart label to be affixed on or integrated in an object and able to provide an electrical signal indicative of the applied pressure or force and/or the position of the applied pressure or force at a touch point on the object to which the label is affixed. The smart label comprises a layer structure and a detector system, the layer structure comprising of at least a stack of a first, a second and a third layer. The first and third layers comprise a flexible, electrically conductive or semiconductive material and at least two electrodes for connecting the layers to the detector system. The second layer comprises a flexible, deformable and compressible material. The second layer is electrically nonconductive or electrically conductive but less conductive than the first and third layers, wherein the second layer separates the first and third layers.

  • TWIGS (Textiles With Integrated Gas Sensors)

    –

    The goal of TWIGS (Textiles With Integrated Gas Sensors) is to design, fabricate and characterise thin-film capacitive gas and temperature sensor platforms robust enough for integration into standard, industrial weaving processes. Each sensor is fabricated on a thin, flexible plastic stripe (made of Kapton®) and is composed of two different sensing devices: a temperature sensor (resistive temperature detector) and a capacitive sensor (consisting of an interdigitated thin-film capacitor coated…

    The goal of TWIGS (Textiles With Integrated Gas Sensors) is to design, fabricate and characterise thin-film capacitive gas and temperature sensor platforms robust enough for integration into standard, industrial weaving processes. Each sensor is fabricated on a thin, flexible plastic stripe (made of Kapton®) and is composed of two different sensing devices: a temperature sensor (resistive temperature detector) and a capacitive sensor (consisting of an interdigitated thin-film capacitor coated with a humidity/gas sensitive polymer). Both sensors are allocated in the central part of the Kapton® stripe and occupy a very small area (1.6 X 1.6 mm2). In order to protect the sensing area from mechanical stress occurring during and after the weaving process, such active area is encircled by a dry foil film and encapsulated by using gas-permeable porous Teflon film. The fabrication process is actually very simple and compatible with large scale roll-to-roll fabrication. It should also be noted that it is possible to build an array of capacitive sensors which, by functionalising each sensor with a different sensing material, is able to perform complex sensing tasks. Reliability of the sensing plastic stripes under mechanical deformation and their processing using fully compatible printing processes are being addressed.
