	UT-Encyclopedia: PVDF (Site not responding. Last check: )
		The electromechanical coupling of PVDF is lower than that of piezoceramic, but since the foil thickness can be as little as 10 micrometres the vibration mass is extremely small.
		PVDF also has greater damping than ceramics, and the resulting dynamic characteristics allow very short pulses to be generated.
		This means that it is possible to measure shorter ranges using PVDF than is possible with piezoceramic transducers.

	PVDF and Array Transducers s
		The main differences between PVDF and other materials that I haven't discussed are it's inherent bandwidth (resolution) and the fact that it is flexible and can be formed into a variety of shapes to suit special applications.
		The fact that PVDF can be bent and formed into complex shapes, it is a plastic so it can be formed to some very complex shapes, allows some previously very costly transducers to be made inexpensively.
		The use of PVDF and it's superior resolution has many advantages in thickness gaging, near surface resolution and bond evaluation applications where maximum resolution is needed and penetration requirements are not severe (moderately lossey materials).

	8717. How to apply/bond PVDF to metals?
		As PVDF is quite expensive, I doubt that any serious fabricator would want to get material which is thick enough to lend itself to easy fusion, ie.
