“…Biopotential signals are generally acquired by physical sensors. Piezoresistive, piezoelectric, and capacitive transduction mechanisms are extensively used for data collection [ 106 , 265 ]. Conductive networks developed by nanomaterials deposition on substrate get disrupted, i.e., the effective mass of charge carriers and distribution of active materials changes under stress and subsequently the resistance of piezoresistive sensors changes [ 266 , 267 ].…”

Electrodes fabricated on a flexible substrate are a revolutionary development in wearable health monitoring due to their lightweight, breathability, comfort, and flexibility to conform to the curvilinear body shape. Different metallic thin-film and plastic-based substrates lack comfort for long-term monitoring applications. However, the insulating nature of different polymer, fiber, and textile substrates requires the deposition of conductive materials to render interactive functionality to substrates. Besides, the high porosity and flexibility of fiber and textile substrates pose a great challenge for the homogenous deposition of active materials. Printing is an excellent process to produce a flexible conductive textile electrode for wearable health monitoring applications due to its low cost and scalability. This article critically reviews the current state of the art of different textile architectures as a substrate for the deposition of conductive nanomaterials. Furthermore, recent progress in various printing processes of nanomaterials, challenges of printing nanomaterials on textiles, and their health monitoring applications are described systematically.

Conductive metallic nanomaterialsConductive metals (such as silver, copper, gold, aluminum, and tin) and metal oxide (TiO 2 and ZnO) nanomaterials exhibit great promise as alternatives to conventional conductive materials [6][7][8]. These conductive metal nanomaterials (nanoparticles or nanowires) can be incorporated in different polymers to make conductive polymer nanocomposites, which can be used further for making conductive fibers or coated textiles. However, in polymer matrices, generally, metal nanowires exhibit better conductivity in comparison to metal nanoparticles because of their better conductive network at lower concentrations and less inter-particle junctions in the case of nanowires [9]. Conductive nanoparticles such Ag, ZnO and TiO 2 dissipate the static charge of synthetic fibers because of their good electro-conductive property and hence, these nanoparticles can be used to develop antistatic fabrics [10][11]. Carbon-based nanomaterialsDifferent carbon-based nanomaterials such as 2D graphite and graphene, 1D CNTs, carbon black etc. are extensively used to increase conductivity of polymer and textiles [12][13][14]. The electrical conductivity, of pure CNT can be as high as 10 6 to 10 7 S m -1 and for pure graphene, it can be up to 10 5 S m -1 . On the other hand, the thermal conductivity value of CNT may vary between 2800-6000

Moreover, a study from the World Health Organization (WHO) emphasized that death due to heart diseases and diabetes is still an upward trend and expected to be the first and seventh leading causes of death, respectively, by 2030. [16] Therefore, early diagnosis and treatment is urgently on demand. [12,17] A variety of human health-detection devices, intelligent wearable devices, and medical intelligent devices as efficient strategies have been emerging and making a big difference in daily life, [18][19][20][21][22][23] making it higher efficient, more accurate, more timely than traditional detection techniquesIn the meanwhile, sensors, as a vital component in intelligent detection devices quickly bloom to meet the requirement of high sensitivity, wide detection range, and stable response sensing capability. Sensors work through transforming external stimulus including biological, chemical, and physical changes into electrical signals changes. According to their respective work mechanism, sensors can be classified into the following several categories: piezoresistive, [24][25][26] piezoelectric, [27][28][29] frictional, [30] and capacitive. [31][32][33][34] Among them, piezoresistive sensors have attracted extensive concern for its simple structure, low cost, and easy signal acquisition, further being applied to the field of wearable detection devices. [35,36] It works by transforming external stimulus into visual electrical signals, and the change of resistance is generated by microscopic deformations of its own structure. [37][38][39][40] From sensors functional point of view, sensors can also be divided into strain sensors, [39,[41][42][43][44] stress sensors, [45,46] humidity sensors, [47] gas sensors, [41,48,49] temperature sensors, [50] and so on. On the present overall view, the key issue focuses on how to realize ideal sensors compatible with high sensitivity, wide detection range, ultralow response time, ultralow detection limitation, superb linearity, and cyclic stability. [51][52][53][54][55][56][57][58][59][60] What is noteworthy is that conductive materials interacting with other substances have been considered as an extremely efficient strategy to realize high sensing performance, being able to give out fast response reacting to outer tiny changes. Currently, aiming to endow sensors superb sensitivity and wide sensing range, flexible substrates for sensors commonly choose polydimethylsiloxane (PDMS), hydrogenated styrene-butadiene block copolymer (SEBS), and silicone rubber and other high elastic polymer materials. [37,57,61,62] Then, the composite sensor is fabricated successfully by different preparation techniques including With the advent of the era of intelligent manufacturing, sensors, with various detection objects, have set off a wave of enthusiasm and reached new heights in medical treatment, intelligent industry, daily life, and so on. MXene, as an emerging family of 2D transition metal carbides/nitrides, possesses impressive electrical conductivity, outstanding structural controllability, ...
