This work presents a simple, low-cost and practical inkjet-printing technique for fabricating an innovative flexible gas sensor made of graphene–poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) composite film with high uniformity over a large area. An electronic ink prepared by graphene dispersion in PEDOT:PSS conducting polymer solution is inkjet-printed on a transparency substrate...
An unconstrained real-time method to detect the relationship between breathing patterns and sleep efficiency (%SE) during sleep was developed.using a low-cost sleep monitoring system. This system consists of an array of force sensitive resistors (FSR) sensors embedded on a pillow-sheet, wireless network devices based on low-cost ZigBee technology to digitize and transmit the pressure data to desktop...
In this paper, we have developed a low-cost sleep monitoring system for patient based on polysomnography which will be useful for patient communication with healthcare personals and/or relatives. In particular, we have presented the sensor pillow and bed sheet system that employs wireless networks based on low-cost ZigBee technology and a sensor array of force sensitive resistors (FSR) based on polymer...
In this paper, we have developed a communication system for military based on hand gestures which will be useful for squad communication. In particular, we present an electronic soldier glove that employs wireless networks based on low-cost ZigBee technology, multi-functional sensors such as accelerometer and flex sensor based input device for collecting and classifying hand gestures. This system...
