Abstract

In this project we have developed a new generation of bio-inorganic generators aimed at the electricity production from renewable fuels. These systems are presented as an alternative to electrochemical fueled cells. In this context, we have fabricated a new hybrid system, which fuses a biological machinery able to transform chemical energy into mechanical energy (pressure and vibration), with a piezoelectric material who convert such mechanical energy into electricity (bio-inorganic generator). The mechanical stimuli, as pressure and vibration, are generated as an outcome of the produced gases coming from renewable fuels; this reaction is catalyzed by the biological machinery (enzymes) which are part of the generator. These devices are able to produce electricity at the microscopic scale starting from renewable fuels as sugars and alcohols coming from the biomass. This fact is very significant allowing the indirect production of electricity with zero emissions. Moreover, these bio-inorganic generators open a passionate spectrum of new applications in different fields like sensing, robotics and energetics.
