A semiconductor component 150 has a semiconductor layer 1 including a winding wire part 10 and a winding return wire part 50 connected at a terminal end part of the winding wire part 10 and returning from the terminal end part toward a starting end part side, wherein the semiconductor component is disposed so as to surround an object to be measured.

The present disclosure provides an improved Rogowski-type current sensor. The current measurement coil, and the compensation coil are provided on the same board. The measurement coil and the compensation coil are arranged such that they at least partially overlap by virtue of each repeatedly changing side of the board. This arrangement makes the current sensor far better at rejecting interference than certain other PCB Rogowski type coil arrangements.

An end effector assembly for use with an electrosurgical instrument is provided. The end effector assembly has a pair of opposing jaw members. One or more of the jaw members includes a support base, an electrical jaw lead, and a sealing plate coupled to the electrical jaw lead. The sealing plate has a stainless steel layer and one or more piezo electric sensors. The jaw member also includes an insulative plate disposed between the support base and the sealing plate.

Transferring electronic probe assemblies to space transformers. In accordance with a first method embodiment, a plurality of probes is formed in a sacrificial material on a sacrificial substrate via microelectromechanical systems (MEMS) processes. The tips of the plurality of probes are formed adjacent to the sacrificial substrate and the remaining structure of the plurality of probes extends outward from the sacrificial substrate. The sacrificial material comprising the plurality of probes is attached to a space transformer. The space transformer includes a plurality of contacts on one surface for contacting the plurality of probes at a probe pitch and a corresponding second plurality of contacts on another surface at a second pitch, larger than the probe pitch, wherein each of the second plurality of contacts is electrically coupled to a corresponding one of the plurality of probes. The sacrificial substrate is removed, and the sacrificial material is removed, leaving the plurality of probes intact.
