A zigbee based wireless wearable electronic nose using flexible printed sensor array
- 1. A ZIGBEE-BASED WIRELESS WEARABLE ELECTRONIC NOSE USING FLEXIBLE PRINTED SENSOR 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.
