Various embodiments of a biocompatible, self-rechargeable bio-fueling micro battery with a glucose burning chamber, are disclosed herein, to power an implanted medical device. The micro battery comprises a bio-membrane that is configured to diffuse a plurality of bio-fluids across an anode and cathode electrode. The bio-membrane includes: a biocompatible compartment storing at least one of a chemical substance configured to operate a plurality of bio-medical implant devices; one or more bio-fuel compartments (blood, glucose, and/or microbial) configured to store bio-fuels for generating electrolyte and to create a conductive path for electrons emitted by electrodes; and a processor in communication with the biocompatible compartment through plurality of connectors interface with the one or more bio fuel compartments to control the communication between user and the bio medical implant devices. The biofluids comprise a lemon juice, an orange juice, a pineapple juice, and a sour juice; and/or an ingested food.
