Abstract: An electromagnetic property measuring device includes a magnetic conductive structure, a coil, and a scattering parameter measuring unit. The magnetic conductive structure includes a first side facing a sample to be tested and a second side opposite to the first side, and the first side has a magnetic gap. The coil surrounds the magnetic conductive structure to generate a magnetic field with the magnetic conductive structure. The scattering parameter measuring unit is disposed at the first side and located within a range of the magnetic field.

Abstract: An electrostatic sensing system configured to sense an electrostatic information of a fluid inside a fluid distribution component and including an electrostatic sensing assembly, a signal amplifier and an analog-to-digital converter. The electrostatic sensing assembly includes a sensing component, and a shield. The sensing component is configured to be disposed at the fluid distribution component. The sensing component is disposed through the fluid distribution component so as to be partially located in the fluid distribution component. The shield surrounds a part of the sensing component that is located in the fluid distribution component. At least part of the shield is located on an upstream side of the sensing component. The signal amplifier is electrically connected to the sensing component. The analog-to-digital converter is electrically connected to the signal amplifier. The shield has an opening spaced apart from the sensing component.
