An eddy current probe (10) comprises an insert (14); a compliant probe body (12) around the insert, and formed in the shape of a workpiece to be inspected; and a flexible eddy current array circuit (22) on the probe body. An independent claim is also included for a method of manufac...
13c) and/or the total eddy current (Supplementary Fig. 13d) can be used to optimize the amount of heating. Also, the dimension of the heaters (thickness and diameter) can be decreased or the coil-to-heater distance can be increased further by controlling the instrumental parameters such as...

In contrast to metal thermoseeds that generate heat mainly by eddy current loss, ferromagnetic microspheres generate heat predominantly by hysteresis loss.Since it is widely known that clinically relevant heating of tissues can be generated by magnetic hysteresis effects, a preferred embodiment includes ...
This paper focuses on the durability of flexible eddy current array (FECA) sensors in harsh service environments of aircrafts, including vibration environment and several typical exposed environments. First, a kind of FECA sensor is illustrated and its integration method is proposed. Moreover, in ...
