Method of growing electrically conductive tissue

1. A method of making an electrical circuit comprising the steps of

obtaining a sterilized Potato Dextrose Broth containing a metal salt;

obtaining a sterilized Potato Dextrose Agar;

adding the sterilized Potato Dextrose Broth to said sterilized Potato Dextrose Agar to obtain a solution;

inoculating the solution with a macerated tissue culture including a filamentous fungi selected from the group consisting of Basidiomycota, Ascomycota and Zygomycota;

thereafter pouring the inoculated solution into at least one incubation vessel for a time sufficient for a tissue culture to grow across a top surface of the solution while sequestering said metal salt and creating a sheet of tissue;

extracting the sheet of tissue from the solution;

adding a plasticizer to said sheet of tissue;

drying said sheet of tissue; and

subsequently forming a wiring pattern for the electrical circuit in said dried sheet of tissue.

2. A method as set forth in claim 1 further comprising the step of applying additional components to said dried sheet of tissue to make an integrated circuit.

3. A method as set forth in claim 1 wherein said metal salt is one of CuSO 4 , CuCl 2 and Al 2 O 2 .

4. A method as set forth in claim 1 wherein said metal salt is CuSO 4 .

5. A method as set forth in claim 1 wherein a plurality of said sheets of tissue are stacked and subsequently plasticized and dried prior to forming a wiring pattern in a topmost sheet of said stack.

6. An electrical circuit comprising a sheet of mycelium having a wiring pattern for the electrical circuit thereon.
