Abstract:This paper addresses the methods used for the design and fabrication of a capacitance based wearable pressure sensor fabricated using neoprene and (SAC) plated Nylon Fabric. The experimental set up for the pressure sensor is comprised of a shielded grid of sensing modules, a 555 timer based transduction circuitry, and an Arduino board measuring the frequency of signal to a corresponding pressure. The fundamental design parameters addressed during the development of the pressure sensor presented in this paper a… Show more
“…This enables precise tactile sensing by the stretchability of the silver coated knits between the elastomeric knits [128]. While knitting was a found solution, Arogbonlo et al used commercially available conducting fabric of tin/copper over silver coated nylon fabric along with proper device isolation by encapsulation of the pressure sensitive layer [139].

Sensors are becoming more demanding in all spheres of human activities for their advancement in terms of fabrication and cost. Several methods of fabrication and configurations exist which provide them myriad of applications. However, the advantage of fabrication for sensors lies with bulk fabrication and processing techniques. Exhaustive study for process advancement towards miniaturization from the advent of MEMS technology has been going on and progressing at high pace and has reached a highly advanced level wherein batch production and low cost alternatives provide a competitive performance. A look back to this advancement and thus understanding the route further is essential which is the core of this review in light of nanomaterials and printed technology based sensors. A subjective appraisal of these developments in sensor architecture from the advent of MEMS technology converging present date novel materials and process technologies through this article help us understand the path further.

“…Pressure sensors are one of the main application area of e-textiles and can be used in orthotics, sports and rehabilitation products. The production of conductive fabric based pressure sensors is a key area of smart textiles due to their significant final characteristics such as flexibility, lightness, conductivity and process ability [1]. The textile based flexible capacitive, piezoresistive and piezoelectric pressure sensors can be developed by different techniques.…”
Wearable electronic textiles have become increasingly important in daily life. Such garments are based on sensors that are distributed on the human body. These sensors should be comfortable and fit for the aim of the wearer. In general, these textiles have been used for pressure, stretch and temperature sensors. In this study, electrically conductive nonwoven fabrics were prepared by Drop Casting-Drying method and their pressure sensing behavior was investigated.
