Abstract Electrically conductive hydrogels are a promising class of materials for soft electronics and robotics that mimic the mechanics natural biological tissue. However, these typically derived from petrochemical sources their production involves hazardous solvents monomers limit accessibility environmental compatibility. This study introduces biomaterial hydrogel composite in which percolating network silver microflakes is suspended natural, gelatin‐based matrix. The primarily composed inexpensive, food‐safe ingredients fabrication achieved using accessible consumer‐grade equipment. resulting material system mechanically soft, stretchable up to 470% strain, highly 3.1 × 10 3 S cm −1 , with properties can be tailored based on composition processing conditions. In addition experimental characterization its properties, this gelatin shown applicable variety uses cases matter circuitry bioelectronics.
