The lab researches sensing and motors that use electromagnetism.
AboutAbout the lab
Creating technologies for measuring and driving things with electromagnetism.
The Electromagnetic Energy Applications Lab studies the development of advanced sensing systems that use electromagnetism.
In medicine and biology, the lab develops immunoassay devices for disease diagnosis using magnetic markers, and magnetic nano-bioimaging methods using magnetic tracers injected into the body.
In materials evaluation, the lab develops nondestructive testing devices for detecting defects and deterioration inside materials.
The faculty member's researcher profile also lists the development of superconducting rotating machines for aircraft as a research theme.
Key terms
- Magnetic tracer
- A substance injected into the body that serves as a marker, allowing its position and distribution to be detected magnetically.
- Nondestructive testing
- Testing that examines defects and deterioration inside an object without damaging it.
- AC loss
- Energy loss that occurs when alternating current or a magnetic field is applied to a superconducting wire.
ResearchResearch themes
Centered on the development of various advanced sensing systems that use electromagnetism, the lab also works on motors and superconducting applied equipment. Its research ranges from testing and imaging in medicine and biology, and nondestructive testing of materials, to the design and development of superconducting motors.
