“…The fabrication of conductive fabric‐based strain sensors can be performed by coating or integrating the sensing part into textile structure during the manufacturing process. The latter involves the integration of the conductive yarns into the fabric structures via knitting or weaving . These knitted or woven textile‐based strain sensors are further integrated into wearable devices or clothes that are ready‐to‐wear.…”

Human motion analysis consists of real‐time monitoring and recording of human body's kinematics. It is very essential to track ambulatory and daily‐life human motion, which is crucial for many applications and disciplines. Electronic textiles (e‐textiles) afford a valid alternative to traditional solid‐state sensors due to their merits of low cost, lightweight, flexibility, and feasibility to fit various human bodies. In this mini‐review, textile‐based sensor platforms and human motion analysis are well discussed in Section 1. Second, theoretical principles of textile‐based strain sensors are introduced including resistive, capacitive, and piezoelectrical sensors. Section 3 focuses on various types of textile materials that are functionalized as sensing systems by intrinsic or extrinsic modifications. Section 4 summaries various types of e‐textile‐based strain sensors for human motion analysis. The final two sections mainly present perspectives and challenges, and conclusions, respectively.

We have developed an essentially green, bottom-up approach for synthesising flexible, organic, semi-conducting nanocomposite films based on cellulose nanocrystals (CNCs) and polyaniline (PANI) through aqueous emulsion polymerization. Dodecylbenzene sulfonic acid (DBSA) was used as surfactant and dopant for the emulsion. CNCs and DBSA micelle concentrations, their structural organization and alignment with the monomer in the emulsion have a significant effect on the physical and mechanical properties of the resulting nanocomposite films with electrical conductivity reaching as high as 5.29 x 10 -1 S.cm -1 which falls in the electrical conductivity range of germanium (2.24 x 10 -2 S.cm -1 ) and silicon (0.43 x 10 -5 S.cm -1 ) [S. L, Kakani, Electronics Theory and Applications, New Age International, 23-24, 2005.]. The CNCs-PANI-DBSA nanocomposite films show a maximum tensile stress and strain values of 22 MPa and 0.89 %, respectively and are significantly stronger and more flexible films than those obtained with, for instance, graphene/polyaniline composite paper or graphene paper, where it has been reported in the literature that the tensile strengths were 12.6 and 8.8 MPa, and maximum strains, 0.11 and 0.08 %, respectively [Wang et al.

“…The biodegradable properties of green polymeric composites imply the degradation of a polymer in natural environment that includes changes to the chemical structure, the loss of mechanical and structural properties, and conversion into other compounds that are beneficial to the environment . Green polymeric composites have been used effectively in many applications, including mass produced consumer products with short life cycles or products intended for one use or short period prior to disposal . Indeed, it could also be used for indoor applications and remain in use for several years.…”

Owing to their abundance, high strength and stiffness, and low weight and biodegradability, nanocellulose (NC) is regarded as a promising candidate for the preparation of green composites. The high reinforcing effect assigned to the mechanical percolation phenomenon of NC is due to the stiff continuous networks of cellulosic nanoparticles linked via hydrogen bonding. Compared to nanocrystalline cellulose, NC fibers result in more significant improvement to the modulus, stiffness, and strength as aspect ratio NC fiber is higher compared to NC crystal. Indeed, in the case of biopolymer composites, the reinforcement effect of NC is attributed to the NC‐polymer interactions and the reinforcing effect occurring through effective stress transfer at the NC‐polymer interface. The NC‐reinforced composites tend to become more brittle as the concentration of the reinforcing particles increase up to the saturated level, due to the reduction in surface adhesion between filler and matrix. Due to its promising mechanical and structural stability, NC composites have been used widely in many industrial applications such as food packaging, electronic applications, and tissue engineering.
