Abstract

Magnetic nanoparticles are generally smaller than 200 nm surrounding our environment and can easily enter the human brain through the respiratory system. The harm of such nanoparticles may endanger people’s health. This paper focuses on modelling and simulation based on a new kind of magnetic sensors, which can count and localize these magnetite nanoparticles. The proposed sensors could help to prevent these nanoparticles from the polluted environment and undoubtedly reduce their adverse risks to humans. The modelled magnetic system consists of a tunnelling magnetoresistive (TMR) sensor array, a conducting line, and the detected magnetite nanoparticles. The localization and quantization of these nanoparticles can be achieved by analysing total output voltages from the TMR sensor array.
