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.
