“Green” Inkjet-Printed Wireless Sensor Nodes on Low-Cost Paper, Liquid and Flexible Organic Substrates

Abstract

This paper introduces the capabilities of inkjet-printing technology in integrated wireless biosensors on organics bridging RFID and sensing technology. A novel flexible magnetic material is presented as an alternative substrate for wearable biosensors. In addition, a CNT-film is inkjet-printed on paper to realize ultrasensitive gas sensors. The paper concludes with the presentation of novel wearable integration platforms, including liquid antennas, with enhanced-range that could enable multi-hopping algorithms targeting the realization of “intelligent networks of RFID-enabled sensors”.
