Abstract: A super-flexible and super-stretchable magnetic skin includes a silicone-based elastomeric matrix and a magnetic powder that generates a magnetic field. The magnetic powder is distributed through an entire volume of the silicone-based elastomeric matrix, and the super-flexible and super-stretchable magnetic skin has a Young modulus of less than 1 MPa and a yield strain greater than 200%.

Abstract: A subcutaneous medical device system includes a subcutaneous medical device, a magnetic element arranged on a portion of the subcutaneous medical device, the magnetic element including at least two poles, and a magnetic detector arranged spaced apart from the magnetic element and outside of a patient. The magnetic detector includes a single magnetic sensor and a processor coupled to the single magnetic sensor. The processor is programmed to determine a position of the portion of the subcutaneous medical device within the patient based on a static magnetic flux measurement of the magnetic element by the single magnetic sensor without externally applying an external magnetic field to the magnetic element.

Abstract: A system for determining a water cut of a water/oil emulsion includes a water cut sensor with a magnetoelastic ribbon, an inductive coil arranged proximate to the magnetoelastic ribbon so that an electromagnetic field produced by the inductive coil electromagnetically excites the magnetoelastic ribbon, and an alternating current source. A processor is configured to determine the water cut of the water/oil emulsion based on a resonant frequency of the magnetoelastic ribbon while the magnetoelastic ribbon is excited by the inductive coil. A feed line is coupled to the water cut sensor. The feed line includes an electrical coupling between the alternating current source and the inductive coil of the water cut sensor. The feedline includes an electrical coupling between the processor and the inductive coil of the water cut sensor or the processor is coupled to an acoustic sensor.
