“…Now, this technology is also entering the textile world: Textile applications of conductive polymers range from anti-static fabrics or actuators for 'artifi cial muscles' (i.e. stimuli-responsive materials that react by modifying their shape or dimensions), wound dressing products with anti-bacterial properties or temperature, and optical-or strain-gauge sensors (Ferreras, 2011). Ferreras (2011) developed lightweight, low-cost strain sensors by coating fabrics with organic conductor fi lms.…”

“…In order to exploit practically the conducting properties of TTF-based IRS, composite BL films based on polycarbonate (PC) with a conducting topmost layer of an organic molecular conductor based on BEDT-TTF were previously reported. We have shown that these BL films may have a great interest for sensor engineering due to important material properties, such as conductivity, high strain (pressure) sensitivity, excellent elasticity, weightless and biocompatibility [3,4]. Here we show that covering layers based on the α-(BEDT-TTF) 2 I 3 molecular metal, revealing gauge factor 10, can be prepared with different TCR.…”

Covering polycarbonate films with the strain sensing molecular metal α-(BEDT-TTF) 2 I 3 [BEDT-TTF =bis(ethylenedithio)tetrathiafulvalene] was studied at different temperatures. It was shown that depending on the temperature of the covering process the conductive strain sensing layers demonstrate different electric transport properties: they vary from metallic to semiconductor-like temperature behavior. However, the electromechanical properties of all films reveal the same strain sensitivity with gauge factors about 10. This result permitted engineering highly strain sensing films with a very low temperature coefficient of resistance (TCR). Therefore, both of the electric and electromechanical properties of these bi layer (BL) films make them very attractive as flexible, durable, low-cost, all-organic strain (pressure) sensors that are able to replace conventional physical sensors in biomedical high-tech.

This study, being stimulated by the discovery of high sensitivity of nanostructured layers of organic semiconductor α'-BEDT-TTF)2I x Br 3-x [BEDT-TTF= bis(ethylendithio)tetrathiafulvalene] to heat radiation, is strongly related to the field of Organic electronic. This work presents the development and assessment of flexible lightweight highly sensitive filmbased thermistor as (i) a separate sensor, (ii) sensor integrated in e-textile and (iii) sensor embedded in a wireless sensor node. Wireless Sensor Networks (WSN)) and Internet of Things (IoT), being two promising technologies, have been already applied in a number of monitoring scenarios. In spite of great progress achieved in sensing technologies and wireless embedded systems there is a gap in multidisciplinary research aimed at investigation of potential of these technlogies at a time. Experimental results demonstrate that the developed a bi-layer organic thermistor has high potential in an environmental and biomedical monitoring. They can be used as a part of wearable units or as sensing units on board of wireless sensing devices.
