“…The glucose tattoo sensor exhibits a sensitivity of 23 nA/µM and a limit of detection of 3 µM, and a linear response range from 0 to 100 µM. Exploiting two iontophoretic electrodes (anode and cathode) with three amperometric sensing electrodes (working, reference, and counter electrodes) in the anode compartment can also yield a wearable alcohol sensor system (Figure 8d) [46]. By delivering the pilocarpine drug from the anode compartment, iontophoretic electrodes induce the sweat in the anode region for the alcohol analysis with a high sensitivity to detect ethanol (0.362 ± 0.009 µA/mM).…”

“…Additionally, not all types of textiles are suitable to integrate sensing materials [38][39][40]. As an alternative, other flexible thin-film substrates (e.g., paper and plastic) have been explored [41][42][43][44][45][46]. However, the intrinsic fracture limit of the flexible thin-film materials is small (e.g., <1% for paper).…”

The skyrocketing popularity of health monitoring has spurred increasing interest in wearable electrochemical biosensors. Compared with the traditionally rigid and bulky electrochemical biosensors, flexible and stretchable devices render a unique capability to conform to the complex, hierarchically textured surfaces of the human body. With a recognition element (e.g., enzymes, antibodies, nucleic acids, ions) to selectively react with the target analyte, wearable electrochemical biosensors can convert the types and concentrations of chemical changes in the body into electrical signals for easy readout. Initial exploration of wearable electrochemical biosensors integrates electrodes on textile and flexible thin-film substrate materials. A stretchable property is needed for the thin-film device to form an intimate contact with the textured skin surface and to deform with various natural skin motions. Thus, stretchable materials and structures have been exploited to ensure the effective function of a wearable electrochemical biosensor. In this mini-review, we summarize the recent development of flexible and stretchable electrochemical biosensors, including their principles, representative application scenarios (e.g., saliva, tear, sweat, and interstitial fluid), and materials and structures. While great strides have been made in the wearable electrochemical biosensors, challenges still exist, which represents a small fraction of opportunities for the future development of this burgeoning field.

“…In recent work, non-enzymatic glucose sensors with CP-based nanocomposites are becoming new hotspots. Xu et al [315] synthesized a flexible electrochemical sensor based on AuNPs/PANI arrays/CC electrode. The flexible carbon cloth was employed as base electrode, PANI arrays were directly grown on CC electrode, and large number of Au nanoparticles were electrodeposited on the surface.…”

An electrochemical approach towards developing a lead(II) ion selective polymer is presented. A poly(aniline-co-3-aminobenzenesulfonic acid), P(Ani-co-3ABSA), membrane would be reconciled with the peculiarities of lead(II) ions by incorporating them. It seems that consecutive embedding/ejecting of lead(II) into-from the mass of P(Ani-co-3ABSA) coating, correspondingly templates the coating towards lead(II) ion. This method results in a highly selective sensor for the measurement of lead(II) ion. The optimal conditions for sensor operation were ascertained. The surface morphology of the freshly synthesized, templated and templated-preconcentrated P(Ani-co-3ABSA) membranes were explored by SEM. The interference effect on the voltammetric response with coexisting ions was also investigated. The developed sensor was applied for lead(II) determination by pre-concentration/differential pulseanodic stripping voltammetry in concentrations of 1.0 nM to 0.1 mM and by potentiometric method in concentrations of 10.0 nM to 1.0 mM.
