The goal is to design the automation software and development of the electromagnetic mechatronics systems. The physical fields modeling methods are based on the improvement of the distributed current source method, distributed parameter element method, and analytical solutions to formulate the physical fields generated by the mechatronics into the closed-form solutions for design analysis of the system. The DCS method formulates the 2D axis-symmetrical and 3D magnetic and eddy-current fields into state-space representation without considering large air interface and can be utilized in design analysis of electromagnetic mechatronics systems, such as multiple degree of freedom actuators, magnetic sensors, transcranial magnetic stimulation, magnetic impedance topology. The DPE method can formulate two, three dimensional irregular shape objects into state-space representation with different boundary conditions in the applications of the electrical muscle stimulation, electrical impedance tomography, the modeling and parameter estimations of the heat transfer and bio-heat. The multiple objective magnetic eddy-current sensor and electrical impedance tomography will be developed in this research. The former can be utilized in the applications of the estimation of the electrical conductivity with thickness, temperature compensation, positioning of the medical device. The latter can be used in estimations of the electrical conductivity distribution of the object.多重物理場機電系統磁電渦流感測器電阻抗斷層掃描儀multi-physical fieldsmechatronics systemmagnetic eddy-current sensorelectrical impedance tomography
