ZEBROS PROJECTS A ZIGBEE-BASED WIRELESS WEARABLE ELECTRONIC NOSE USING FLEXIBLE PRINTED SSENOR ARRAY ABSTRACT A wearable electronic nose (e-nose) has been developed by integrating a low cost chemical sensor array with a wireless communication for applications in healthcare. Its sensing unit was fabricated by a fully inkjet-printing technique, comprising eight different sensor elements manufactured by varying printing patterns and sensing materials. These sensors have shown response to a wide variety of complex odors. A wearable e-nose prototype using Zigbee wireless technology was designed as a compact armband for monitoring the axillary odor released from human body. Preliminary results based on principal component analysis (PCA) could classify different odors released from the human body upon various activities. DESCRIPTIONS One significant factor concerning reliability of a wearable e-nose is the design of the sensing unit. In this work, we have manufactured a chemical sensor array based on polymer/CNT Nano composites using inkjet printing technology. Inkjet printing as direct-writing technology enables the precise deposition of the designed patterns on a desired area. . With the same materials, distinct sensors can be produced by printing in different patterns to achieve the different responses. The fabricated chemical sensor array has been installed in the sensing unit of the wearable e-nose and also applied to detect a primary odor source from human body, i.e. the odor around the axillary skin. A Zigbee module based on wireless technology was used as an appropriate platform to transfer the data from the wearable e-nose to a computer due to a compact and low-cost component.

ZEBROS PROJECTS This work proposes a novel system of wearable e-nose for healthcare application using a sensing unit based on a fully inkjet-printing technique. Preliminary results have showed the success of classify different odors released from the body of volunteer upon various activities. The sensing unit of this prototype is based on a flexible substrate, thereby posing an advantage for wearable device. Moreover, this feature could be considered as an important step to enable roll-to-roll processing in order to scale up the productivity in the future. The results also demonstrate an advantage of the inkjet-printing technology in order to fabricate the alternative chemical sensors, which provide a unique pattern for each odorant based on using the same sensing materials. They support our previous work about inkjet-printed chemical sensors based on CNT/PSE Nano composites. The methods to produce the different sensing elements were proposed in the same way, i.e. DPL and BSL. However, in this work we have proven the operation for other polymers and used these elements in the sensing unit of the e-nose for real applications. In addition, we also improved the sensor responses by printing multi-layers to increase the amount of sensing material as suggested in the previous work.

What is IEEE? The Institute of Electrical and Electronics Engineers or IEEE (read eye-triple-e) is Incorporated in the State of New York, United States. It was formed in 1963 by the merger of the Institute of Radio Engineers (IRE, founded 1912) and the American Institute of Electrical Engineers (AIEE, founded 1884). A membership organization comprised of engineers, scientists and students that sets standards for computers and communications. It is a nonprofit organization with more than 365,000 members in around 150 countries.
