Can anyone ELI5 this for me ? I am unable to access the paper and the abstract is way too technical for me to make sense. If I understand this right, they are using friction to generate power, but how are they doing Bluetooth wireless transmission ? Is the bluetooth circuit and antenna also printed on the paper ?

I worked on a project with Novalia a few years back, they have a simple way of explaining their tech: https://www.novalia.co.uk/platforms/

We needed a small battery coin for some unique interactions, not sure if that was needed, & not sure/didnt read what Purdue is doing different with self-power.
