Design Considerations for High-Pressure Reciprocating Compressors for Refinery Services

A ferrofluid-based wireless pressure sensor

This paper presents a wireless pressure sensor design based on magnetic fluid displacement over a planar coil and its corresponding inductance change. The design of the pressure sensor is presented followed by its fabrication and characterization. Experimental results show a good correlation with a nonlinear model relating the applied pressure to the change in coil self-resonant frequency. A pr...

3-D RF Coil Design Considerations for MRI

High-frequency coils are widely used in medical applications, such as Magnetic Resonance Imaging (MRI) systems. A typical medical MRI includes a local radio frequency transmit/receive coil. This coil is designed for maximum energy transfer or wave transfer through magnetic resonance. Mutual inductance is a dynamic parameter that determines the energy quantity to be transferred wirelessly by ele...

Energy Harvesting for Tire Pressure Monitoring Systems: Design Considerations

As of September 2007, all cars sold in the United States must be equipped with a Tire Pressure Monitoring System (TPMS). Pending legislation in the European Union and some Asian countries makes universal adoption likely in many parts of the world. Given this large mandated market along with the fact that current TPMS modules require a battery for operation, interest in energy harvesters for TPM...

Static Coil Design Considerations for the Magnetic Resonance Imaging

One of the main challenges in developing magnetic resonance imaging (MRI) systems is to create a static coil that needs to generate magnetic field density along with the characteristics of optimal homogeneity and magnitude size. To do this, two N42 Block PMs are used and the iron core is designed and optimized in accordance with the dimensions of PM pieces using ANSYS Maxwell software. Then, al...
