Paper Abstract

Wire-free power supplies provide portability, flexibility and cost efficiency as they reduces hardware complexity. Thus, in this paper we designed a portable pH sensor based on a microbial fuel cell (MFC) as a wire free energy source. Our MFCs supplied 0.127 mW to power our ultra-low power portable pH sensor. The error of the newly designed pH sensor is less than 5% when pH is between 4 and 10. Also it provides, an autonomy of 4 hours when the pH sensor is continuously used.
