Development of spatial pulse diagnostic apparatus with magnetic sensor array

We studied the development of spatial pulse diagnostic apparatus with magnetic sensor array using giant magnetoresistance (GMR)/spin valves (SV). Magnetic field distributions for the permanent magnet of 10 arrays using the finite element method (FEM) in a sensing surface were simulated. The characteristics of GMR/SV sensor array consisted of the boundary limit of the sensing magnetic fields and the sensitivity of DMR/DH below 20 Oe and 1%/ Oe, respectively.
