Green Inertial Sensors based on Bacterial Cellulose

n this paper, an environmentally friendly inertial sensor is proposed and characterized. The sensor has been realized by using bacterial cellulose, impregnated by using ionic liquids, and covered by conducting polymers, as the electrodes. The composite has mechano-electric transduction capabilities, which are exploited for realizing a generating sensor. More specifically, the system is mounted in cantilever configuration and used for sensing the anchor acceleration. Results of the chemical and transduction characterization of the composite as an accelerometer are reported in the paper.
