I wonder if circuits printed on paper would yield themselves to the same specialized applications as flexible PCBs. For example, there are many variations of custom-made Dactyl keyboards, most of which require hand-wiring to accommodate for the curved shape of the design: https://github.com/adereth/dactyl-keyboard https://github.com/adereth/dactyl-keyboard Innovative designers have come up with alternatives that rely of flexible PCBs. The most recent example I recall is the Bastyl keyboard: https://www.reddit.com/r/mechmarket/comments/jvacs6/gb_bastyl_split_ergonomic_keyboard/ https://www.reddit.com/r/mechmarket/comments/jvacs6/gb_basty... I don't know how to even begin prototyping with flex PCBs, but that barrier to entry may be lessened with paper circuits like these.
