“…In accordance with the changes in the stimulus to the system or device, the corresponding changes in the characteristics of the electric field are analyzed to determine the changes in the MUT. The penetration depth of the electric field is altered by altering the spatial wavelength (distance between the electrodes of the same polarity), which makes it a favorable option for domestic (Nag et al 2016), industrial (Zia et al 2011;Zia et al 2014;Zia et al 2015) and scientific (Afsarimanesh et al 2017;Afsarimanesh et al 2016;Alahi et al 2018) applications. Due to the flexibility of the sensor prototypes, there is a subsequent change in their responses as a result of the applied stress.…”

This chapter elucidates the working principle of the different sensor prototypes that have been explained in the subsequent chapters. The electrodes of all the sensors were shaped in an interdigitated manner, working on the capacitive principle. Due to the flexible and interdigital nature of the sensors, the developed prototypes displayed dual nature of functionality. They were operated as electrochemical sensors with different solutions and as strain strains as a result of a change in dimensions with induced pressure. The sensors were conjugated with electrochemical impedance spectroscopy to determine the changes in impedance values with respect to different inputs provided as per specific applications.

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.

“…In planar IDE structures, approximately half of the electric field lines pass through the polymeric coating, and the rest pass through the substrate. Given that the dielectric substrate (SiO2 in most of the studies) is not altered in the presence of analytes, the sensor's response (capacitance change) [20][21][22][23][24] is approximately half of the maximum response (if the substrate would be of the same polymeric sensing material). This has a pronounced effect on the sensing performance of the device.…”
