We report our recent results on the development of miniature glucose/oxygen enzymatic flow-through fuel cells for healthcare applications. The fuel cells implement non-toxic highly porous gold (hPG) electrodes and do not require any external mediators to facilitate the electrical communication between the enzyme redox centre and the electrode. We demonstrate power generation from transdermal fluid, obtained by reverse iontophoresis from pig skin, and prove the hPG electrodes stability towards the typical impurities of biological fluids (i.e. small proteins, amino acids). These exciting results are a step forward towards the use of EFCs for wearable healthcare devices.
