“…To solve these issues, fiber or textile‐based wearable sensor devices and systems have been intensively studied. Among many different types of sensor devices, strain/motion and touch/pressure sensors have been of great interest . In order to realize these various types of sensors in textile platform, electrically conducting fibers are typically necessary in order to detect or sense the changes of strain, touch, and pressure and convert them into electrical signals.…”

Wearable electronics are emerging as a platform for next-generation, human-friendly, electronic devices. A new class of devices with various functionality and amenability for the human body is essential. These new conceptual devices are likely to be a set of various functional devices such as displays, sensors, batteries, etc., which have quite different working conditions, on or in the human body. In these aspects, electronic textiles seem to be a highly suitable possibility, due to the unique characteristics of textiles such as being light weight and flexible and their inherent warmth and the property to conform. Therefore, e-textiles have evolved into fiber-based electronic apparel or body attachable types in order to foster significant industrialization of the key components with adaptable formats. Although the advances are noteworthy, their electrical performance and device features are still unsatisfactory for consumer level e-textile systems. To solve these issues, innovative structural and material designs, and novel processing technologies have been introduced into e-textile systems. Recently reported and significantly developed functional materials and devices are summarized, including their enhanced optoelectrical and mechanical properties. Furthermore, the remaining challenges are discussed, and effective strategies to facilitate the full realization of e-textile systems are suggested.

“…In addition, excellent water-repellent activity of TiO 2 nanoparticles was revealed. 71 In this study, the addition of nano-TiO 2 to chitosan coatings decreased the water permeability of the calico fabric. If moisture vapour does not freely pass through the fabric, it causes we at accumulation and discomfort by preventing the body sheat dissipation.…”

In this study, chitosan is obtained from the waste shells of crayfish ( Astacus leptodactylus) and characterized. The crayfish chitosan was coated on cotton fabrics using the padding-drying method. The surface properties, flammability and water and air permeability properties of these coatings based on chitosan and a combination of chitosan and nano-TiO2 were determined. The weight of green calico fabric increased to 24.76% after coating with chitosan, while the weight of the blue dyed denim fabric increased to 5.19%. The chitosan coating increased the tear strength of the calico fabric by 20% in the weft direction. Thermogravimetric analysis and vertical burning tests show that chitosan improves the thermal resistance and flame retardancy performance of denim fabrics. While the amount of residue due to thermal degradation of the blue dyed denim fabric was 16.78%, it increased to 34% after coating with chitosan+nano-TiO2. The chitosan coating reduced the mass loss caused by thermal degradation in green calico fabric from 86.3% to 66.0%. Chitosan also improved the post-flame combustion performance of fabrics. While the ember burning time is decreased to 6s in the chitosan-coated dyed calico fabric, this did not occur in the chitosan+nano-TiO2-coated dyed denim fabric.

“…They stated that the coating of PANI on functional MWCNT reduced its entanglement and enhanced the interfacial interaction between the nano fillers and TPU, leading to improved strain sensitivity. Other investigators [9][10][11] also showed that PANI composites have superior strain sensitive properties.…”

Polyaniline (PANI)/11% Multi-carbon nanotubes (MWCNT) nanocomposites sensors were synthesized through an in situ polymerization method. Frits compression method was adopted to make PANI/MWCNT. Transmission Electron Microscopy (TEM) and Scanning Electron Microscopy (SEM) tests results showed that this technique produced a coating of PANI onto the MWCNT, which indicated that CNT were well dispersed in the polymer matrix. Several tests were run to evaluate the sensor's capabilities. The free end vibration test results showed that the double sided attachment of the sensor had higher damping ratio values than single sided attachment. Also, damping ratios were higher when the sensor was placed at the clamped end. Further, the strain sensing properties of PANI/MWCNT sensors were compared with the conventional foil strain gage. The dynamic sensing test results showed that over the range of 10-1000 Hz, the PANI/MWCNT composite sensor was consistently superior to the traditional foil strain gage for sensing purposes.
