Moving ahead, I went on to research on the various possible sensors that I could use, make, or embed into the paper to make it “smart”. I ended up selecting thinpot linear potentiometers (because of their accuracy, thinness, and flexibility), conductive paint, laser cut the paper to make it easier to prototype using rectangles of conductive paint per word rather than screen printing it, capacitive sensing boards, LCD screen, shift registers, multiplexers, music player and amplifier, mini speakers, etc.
I played around with them for quite some time and also had to work on the serial communication which was required for working with all these devices.
Here are some early testing of individual component photos:
