“…[23][24][25][26] Accordingly, they are divided into different categories, such as strain sensors, [27][28][29] pressure sensors, [20,30] temperature sensors, [31][32][33][34] and humidity sensors. [33,35,36] In this section, the working principles of different categories of textile-based strain sensors will be explained. The underlining working principle for typical strain sensors is to detect the electrical signals under varying strains.…”

Human motion analysis consists of real‐time monitoring and recording of human body's kinematics. It is very essential to track ambulatory and daily‐life human motion, which is crucial for many applications and disciplines. Electronic textiles (e‐textiles) afford a valid alternative to traditional solid‐state sensors due to their merits of low cost, lightweight, flexibility, and feasibility to fit various human bodies. In this mini‐review, textile‐based sensor platforms and human motion analysis are well discussed in Section 1. Second, theoretical principles of textile‐based strain sensors are introduced including resistive, capacitive, and piezoelectrical sensors. Section 3 focuses on various types of textile materials that are functionalized as sensing systems by intrinsic or extrinsic modifications. Section 4 summaries various types of e‐textile‐based strain sensors for human motion analysis. The final two sections mainly present perspectives and challenges, and conclusions, respectively.

“…It has been widely acknowledged that ink-jet fabrication technology is a cost-effective method for manufacturing humidity sensors [25,26]. Ink-jet printed GO has been used in temperature-modulated resistive humidity sensors which employ CMOS micro-electro-mechanical-system microhotplate technology for the monitoring and control of indoor air quality [27].…”

This paper presents design, fabrication and characterization of flexible capacitive graphene oxide (GO) based humidity sensors, which can be used in many applications, such as environmental protection, civil engineering, and agriculture. They consist of interdigitated electrodes ink-jet printed on a polyimide flexible substrate and GO based sensing layer. Measurement setup for testing and characterization was developed in laboratory conditions. The dependence of the capacitance and resistance of the GO based humidity sensors on the percentage of the applied humidity is presented. The main advantage of developed GO based capacitive humidity sensors is very large variation of capacitance, almost five orders of magnitude, compared to the previously demonstrated sensors. The other advantages of the sensors are fast response-recovery time, excellent reproducibility of the measurement results and use of cost-effective additive ink-jet technology.

“…Textronic sensors should meet a lot of special requirements, not only electronic ones but also textile ones. Apart from sufficient electrical parameters, such as a high temperature coefficient of resistance (TCR), accuracy and repetitiveness they should be flexible, light and easily integrated into the fabric [3]. The basic sensor structure consists of a flexible substrate -polyimide foil -Kapton ® (75 μm), gold-plated copper contacts (35 μm) and thermoresistive layer, made of a carbon polymer composite with a SBS-modified polystyrene binder (42.9% of carbon filler by mass content).…”

The aim of this paper is to present design and simulation results of the novel flexible temperature sensor. Results of the compact analytical model were compared with the parameters of the obtained real structure. The carbon polymer composition with a SBS-modified polystyrene binder, characterized by a good Temperature Coefficient of Resistance (TCR), was used as a thermosensitive material. The complex electrical analysis of the typical resistive structure geometry was performed with the aid of the COMSOL Multiphysics® 4.4 environment. Streszczenie. Celem niniejszego artykułu jest zaprezentowanie wyników dotyczących projektowania i modelowania nowatorskich elastycznych czujników temperatury przy wykorzystaniu środowiska COMSOL Multiphysics® 4.4.
