Do you really understand the problem? Did you read the original reference?
The OP needs a "cable" that generates a voltage when it is deformed by the music and then this active cable is connected by normal cable out to an amplifier etc.
Saying "Just trust to ask for teflon based insulator..." doesnt really tell me anything. Are you saying teflon generate signals when deformed?
Please explain what you are trying to get me to guess.
I only entered this discussion when you said "Normal" coax would do the job but so far you have not provided ant evidence to show that is true.
