“…[ 33 ] Since pressure applied to the structure results in an even distribution of stress throughout the surface, most sensors used for biosensing applications are circular or cylindrical in shape. [ 34 ] This even distribution helps to enhance the output of the device, this has been proved by simulation studies done in COMSOL. [ 27 ] In contrast to the block, the cylindrical surface has a homogeneous distribution of stress when the other parameters such as dimensions, thickness, and material are similar.…”

The development of triboelectric nanogenerator technology has many benefits across various fields, particularly in healthcare applications; herein, a concise single‐electrode pulse sensor with a high output performance at a reasonable cost is suggested. The device is made up of a polydimethylsiloxane film with a spacer‐created trench structure stacked on top of a graphene‐coated polyethylene terephthalate film. A comprehensive examination of sensor fabrication together with material and electrical characterization is explained. The entire study is carried out using a graphene–silver composite electrode device, giving an output performance of ≈1.66 and ≈2.9 V for tapping movement in plain and microstructured triboelectric surfaces, respectively; however, for the graphene electrode device, the output obtained is ≈5.5 V. This wearable sensor can successfully extract the typical human wrist pulse, which displays the pressure wave from the radial artery in the range of ≈5 V with the help of an exemplary amplifier circuit and will be suitable to integrate with IoT.

“…TRL may be highly useful in deciding between numerous different technologies that provide the same job (Héder, 2017;Olechowski et al, 2020;BHATTACHARYA et al, 2022). To define the sensitivity of developed nanobiosensors, testing is often utilized to calibrate these tools (Zhou et al, 2015;Gauglitz, 2018;Basicairdata, 2023). TRL 5 to TRL 8 levels of testing procedures would be connected, with different environments and methods for the assessment of sensor performance (Waldmann et al, 2010;Achterberg et al, 2020).…”

A nanobiosensor is a tool that converts a biological stimulus into an electrical output via nanosized transducer elements. Nanobiosensors are promising instruments, especially in biomedical applications in the literature and industry. To develop a nanobiosensor from idea to product, a life-cycle approach that comprises various processes ranging from conception through commercialization is required. Developers and potential investors should examine market requirements, design possibilities, feasibility, financial return, and risk assessments when developing a nanobiosensor development concept. It is critical to establish a well-defined regulatory pathway for bringing innovation to market at a low cost and in a short period. R&D should conduct thorough examinations of nanomaterial toxicity and health effects, involving marketing, advertising, and financial analysis. Stakeholders should discuss technology transfer office protocols for faster, healthier operations.

“…The sensitivity of a sensor is generally defined as the ratio between a physical parameter and the output signal generated from that physical parameter [ 58 ]. The general equation (Equation (1)) is shown below: Sensitivity (S) = ΔY/ΔX where Y = output signal variation and X = input signal variation.…”

The elevated concentrations of various trace metals beyond existing guideline recommendations in water bodies have promoted research on the development of various electrochemical nanosensors for the trace metals’ early detection. Inspired by the exciting physical and chemical properties of nanomaterials, advanced functional nanocomposites with improved sensitivity, sensitivity and stability, amongst other performance parameters, have been synthesized, characterized, and applied on the detection of various trace metals in water matrices. Nanocomposites have been perceived as a solution to address a critical challenge of distinct nanomaterials that are limited by agglomerations, structure stacking leading to aggregations, low conductivity, and limited porous structure for electrolyte access, amongst others. In the past few years, much effort has been dedicated to the development of various nanocomposites such as; electrochemical nanosensors for the detection of trace metals in water matrices. Herein, the recent progress on the development of nanocomposites classified according to their structure as carbon nanocomposites, metallic nanocomposites, and metal oxide/hydroxide nanocomposites is summarized, alongside their application as electrochemical nanosensors for trace metals detection in water matrices. Some perspectives on the development of smart electrochemical nanosensors are also introduced.
