Sumario:This study is stimulated by the discovery of high sensitivity of nanostructured layers of organic semiconductor α′-BEDT-TTF)2IxBr3-x [BEDT-TTF = bis(ethylendithio)-tetrathiafulvalene] to heat radiation. We present the development and assessment of the flexible lightweight highly sensitive film-based thermistor as (i) a separate sensor, (ii) a sensor integrated in e-textile and (iii) a sensor embedded in a wireless sensor node. Wireless Sensor Networks (WSN) and Internet of Things (IoT), being two promising technologies, have already been 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 investigating the aggregate potential of these technologies. Experimental results demonstrate that the developed bi-layer organic thermistor has high potential for environmental and biomedical monitoring. They can be used as a part of wearable units or as sensing units on board of wireless sensing devices.
