A practical procedure for printing a real designed FM (Frequency Modulation) radio circuit on flexible and transparent substrate using liquid metal printer was established. Necessary electronic components are then assembled on this circuit board. To enhance the mechanical stability of the FM radio circuit board, we further package the circuit board using Room Temperature Vulcanizing (RTV) silicone rubber. Lastly, an efficient way to recycle the liquid metal ink and electronic components is presented at the end of circuit board’s lifecycle.
