  • Patent number: 11411227
    Abstract: 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.
    Type: Grant
