Original experiments with the eddy-current array used a flexible printed circuit array with 64 coil pairs, each one 4 mm in diameter. The engineering prototype board expanded the size to 256 coil ...

Eddy current testing is a well-established method of nondestructive testing that is used to examine nonferrous/nonmagnetic materials such as condenser and heat exchanger tubes in power generation ...

The consistent inspection of aircraft components and machinery is imperative to maintain prior to the assembly of the aircraft, as well as throughout the lifetime of its use. Aircrafts are cycled, ...
