Extended Data Fig. 7: Comparison of material design methods.

Three methods are explored in this research that are capable of combinational logic network programming on soft material substrates. Schematics of the material and conductive network for the 2-bit adder by utilizing (a) the Standard Sum of Product (SSoP), (b) the Quine–McCluskey Sum of Product (QMSoP) and (c) the Substitution Method (SM). Compared to the SSoP, the QMSoP 2-bit adder significantly reduces both the quantity of switches and unit cells to 32 and 44, respectively. The SM further reduces the 2-bit adder to 24 switches and 36 unit cells.
