The development of smart polymer materials is reviewed and illustrated. Important examples of these polymers include conducting polymers, ionic gels, stimulus-response be used polymers, liquid crystalline polymers and piezoelectric materials, which have desirable properties for use in wearable sensors. This review outlines the mode of action in these types of smart polymers systems for utilisation as wearable sensors. Categories of wearable sensors are considered as tattoo-like designs, patch-like, textile-based, and contact lens-based sensors. The advantages and disadvantages of each sensor types are considered together with information on the typical performance. The research gap linking smart polymer materials to wearable sensors with integrated power systems is highlighted. Smart polymer systems may be used as part of a holistic approach to improve wearable devices and accelerate the integration of wearable sensors and power systems, particularly in health care.

“…In addition to blood samples, sweat contains various health-related biomarkers including biomolecules [e.g., ascorbic acid (AA) and uric acid (UA)], metabolites (e.g., glucose and lactate), and electrolytes (e.g., Na + and K + ) and thus has been chosen for noninvasively assessing individual's physiological state by detecting biomarkers in sweat (6,7). Pioneer researchers have developed various noninvasive and flexible sensors for sweat analysis, including colorimetric sensors (8)(9)(10), electrochemical sensors (11)(12)(13), and fluorescence sensors (14,15). The electrochemical method is the most popular way owing to advantages of relatively high sensitivity and selectivity, rapid response, as well as good compatibility (16)(17)(18)(19).…”

Wearable sweat analysis devices for monitoring of multiple health-related biomarkers with high sensitivity are highly desired for noninvasive and real-time monitoring of human health. Here, we report a flexible sweat analysis patch based on a silk fabric–derived carbon textile for simultaneous detection of six health-related biomarkers. The intrinsically N-doped graphitic structure and the hierarchical woven, porous structure provided the carbon textile good electrical conductivity, rich active sites, and good water wettability for efficient electron transmission and abundant access to reactants, enabling it to serve as an excellent working electrode in electrochemical sensors. On the basis of the above, we fabricated a multiplex sweat analysis patch that is capable of simultaneous detection of glucose, lactate, ascorbic acid, uric acid, Na+, and K+. The integration of selective detectors with signal collection and transmission components in this device has enabled us to realize real-time analysis of sweat.

“…Compared with some other analytical methods, colorimetric analysis is simple and can be read out by the naked eye without the aid of sophisticated instruments, thus realizing the visual on-site analysis [13] [14] [15] [16]. There have been only a few reports about colorimetric OTC detection methods so far, which based on the formation of gold nanoparticles [13] or aggregation of gold nanoparticles [14] [17].…”

“…Thus, it is still a great challenge to establish more convenient and reliable label-free colorimetric strategies for the sensitive OTC detection. The chromogenic reaction between 3,3',5,5'-tetramethylbenzidine (TMB) and an oxidizing agent has been widely applied to the construction of label-free colorimetric sensing system [16] [18]. It has been reported that some ion possessing ability to oxidise TMB, such as Fe 3+ , [19] Ag + , [16] ClO − , [18] and produce a blue oxidation product.…”

Oxytetracycline (OTC) is a common antibacterial agent used for the control of animal diseases. OTC abuse can seriously affect human health. Herein, based on the Fe(III)-3,3',5,5'-tetramethylbenzidine (Fe(III)-TMB) system, a facile and rapid colorimetricassay for oxytetracycline (OTC) was successfully developed. The addition of OTC could remarkably enhance the Fe(III)-oxidized TMB reaction and the absorbance increase of Fe(III)-TMB solution is proportional to the added OTC. The linear range of proposed sensor for OTC was from 20 nM to 1000 nM with the detection limit of 7.97 nM. The high sensitivity for OTC detection was successfully achieved under optimal conditions. For real sample analysis, recoveries of 89.93% to 100.02% was obtained. This is the first report for detecting OTC based on the nonenzymatic colorimetric reaction using the intrinsic oxidized activity of OTC/Fe 3+ complex. The present simple, low-cost and visualized sensor has great potential for OTC detection in food.
