Disclosed and described herein are systems and methods of energy generation from fabric electrochemistry. An electrical cell is created when electrodes (cathodes and anodes) are 'printed' on or otherwise embedded into fabrics to generate DC power when moistened by a conductive bodily liquid such as sweat, wound, fluid, etc. The latter acts, in turn, as the cell's electrolyte. A singular piece of fabric can be configured into multiple cells by dividing regions of the fabric with hydrophobic barriers and having at least one anode-cathode set in each region. Flexible inter-connections between the cells can be used to scale the generated power, per the application requirements.

Energy generation from fabric electrochemistry

Highly active and stable platinum-copper (PtCu) electrocatalysts are provided. The PtCu catalysts can be in the form of discrete, spherical PtCu nanoparticles that include a particle interior comprising platinum and copper, and a surface layer comprising platinum surrounding the particle interior. The PtCu nanoparticles can exhibit enhanced oxygen reduction reaction (ORR) activity as compared to other Pt-based catalysts for ORR. The PtCu nanoparticles are also active as electrocatalysts for the oxidation of small molecule organic compounds, including alcohols such as methanol and ethanol.
