Hii, I want to create a touch sensitive wire strip... That is .. When i move my hand over a copper wire
Well, there is not much variation in voltage along a copper wire...
On a technical note, this applies only if the length of the wire is short compared to the wavelength of the signal.
Are you referring to SWR?
No, I'm referring to the propagation of a signal through a conductor.
If the conductor is short compared to the wavelength, you can consider the signal identical throughout the length of the wire, and the signal at both ends are the same.
If the wire is long, both ends of the wire could be at different potentials.
As toy realize, an antenna is a perfect example. However, regardless of SWR the effect still happens.
