An abiotic biofuel cell composed of catalytic electrodes modified with inorganic nanoparticles (NPs) deposited on carbon black (CB) was used to activate a wireless information transmission system. The cathode and anode were made of carbon paper modified with Pt-NPs/CB and buckypaper modified with Au80Pt20-NPs/CB, respectively. The cathode/anode pair was implanted in orange pulp extracting power from its content (glucose and fructose in the juice). The open circuit voltage, V-oc, short circuit current density, j(sc), and maximum power produced by the biofuel cell, P-max, were found as 0.36 V, 1.3 mA cm(-2) and 182 mu W, respectively. The voltage produced by the biofuel cell was amplified with an energy harvesting circuit and applied to a wireless transmitter. The present study continues the research line where different implantable biofuel cells are used for activation of electronic devices.
