“…Although the dispersion of the fillers can be improved with the addition of surfactants, these ordinary surfactants are insulating that may reduce conductivity. Accordingly, conducting surfactants, such as poly(3-hexylthiophene) and poly (3,4-ethylenedioxythiophene):polystyrene sulfonate, have been employed to improve the dispersion of the conductive fillers while maintaining conductivity between adjacent particles [53][54][55].…”

“…So, these types of sensors have been developed with techniques like screenprinting [59], spin-coating [60], where a separate membrane of enzymes like cholesterol esterase [59], cholesterol oxidase [61] had been immobilized on the sensing surface. Pressure [62,63] and strain [64,65] sensors are one of the most standardized applications of flexible sensors. Different kinds of piezoresistive and piezoelectric sensors have been developed till date to monitor various physiological parameters by using them as bandages, gloves, etc.…”

Abstract-The paper provides a review on some of the significant research work done on wearable flexible sensors (WFS). Sensors fabricated with flexible materials have been attached to a person along with the embedded system to monitor a parameter and transfer the significant data to the monitoring unit for further analyses. The use of wearable sensors has played a quite important role to monitor physiological parameters of a person to minimize any malfunctioning happening in the body. The paper categorizes the work according to the materials used for designing the system, the network protocols and different types of activities that were being monitored. The challenges faced by the current sensing systems and future opportunities for the wearable flexible sensors regarding its market values are also briefly explained in the paper.

This work introduces a simple and low-cost microfabrication technique utilizing laser ablation to embed conductive elastomer nanocomposite within an insulating bulk elastomer. Nanocomposite consisting of poly(dimethylsiloxane) and a network of carbon nanotubes functions as a piezoresistive sensor material. Microstructures are embedded with the assist of laser ablation which utilizes a focused laser beam to ablate through a thin polymer film following a path programmed via software. This approach eliminates hardware such as photo-mask or stamp, which offers distinct advantages in reducing fabrication time and cost in prototyping of sensor devices. Various patterns of polymer film and embedded nanocomposite are demonstrated with spatial resolution down to 34 lm. To characterize patterning quality, different fabrication conditions are tested and uniformity (width, thickness) data are measured with optical profiling. Sensor prototypes are demonstrated based on the piezoresistive response of nanocomposite under tensile strain. Strain sensors could detect large-range ([45%) tensile strain with sensing a factor of about 4, showing promising feasibility for various sensing applications.
