Abstract

The possibility to create hybrid devices has arisen recently. A high interest has grown around the use of organic materials in engineering and electronic fields. One of the most interesting biomaterial is cellulose, which is the most abundant polymer in nature. In particular, it exhibits high degree of crystallinity, stability and withstanding to high temperatures, moreover may be easily tailored to its application requirements. ZnO has been used as active sensing material thanks to its well-known performances and to the room temperature sensing by UV light activation. A new generation of bacterial cellulose based MOX sensors have been successfully developed. The prototypes showed good response to ethanol, hydogren, nitrogen dioxide and acetone at room temperature, demonstrating the possibility to use cellulose as eco and environmental friendly transducers for, but not limited to, chemical sensors.
