In some examples, an electromagnetic (EM) shielding tile is described. The EM radiation shielding tile may include one or more of an EM radiation shielding fabric layer, a mu metal layer, and/or a microwave absorbing layer. In some cases, the EM radiation shielding tile may be configured to bond to clothing, electronic devices, or other objects to deflect and/or absorb electromagnetic field radiation.

A board includes a first magnetic conductive plate and a second magnetic conductive plate. The first magnetic conductive plate has a first magnetic conductive direction. The second magnetic conductive plate overlaps with the first magnetic conductive plate. The second magnetic conductive plate has a second magnetic conductive direction. The first magnetic conductive direction and the second magnetic conductive direction cross.

A connector for use with a sensor, such as a pressure sensor, has EMI absorbing capabilities. The connector includes a polymeric body configured for coupling to a sensor body and an EMI absorbing material. The EMI absorbing material may be entrained in the polymeric body, coated on the polymeric body, or otherwise integrated with the polymeric body. The EMI absorbing material may be carbon black or carbon nanotubes.

A method for producing a magnetic material includes: selecting a mixture of isotopes of a chemical element having a desired magnetic characteristic; identifying an isotope in the mixture of isotopes meeting a selection criterion; removing the identified isotope from the mixture of isotopes using an isotope separation device to produce an enriched mixture of isotopes having a decreased concentration of the identified isotope; wherein the enriched mixture of isotopes is the magnetic material.
