The simulation study of a microprobe for investigation of electrical impedance/temperature property of biological tissues

The measurement of electrical impedance/ temperature property of biological tissue is of great importance to develop electrical impedance method for the monitoring of hyperthermia process. Through software simulation and theoretical analysis, the authors present an original design of an impedance microprobe to measure the electrical impedance/ temperature property of biological tissues in a minimally invasive way and realize it. The microprobe has advantages of small size, small sensing volume, convenient for application, etc. Then, the basic performance test has been down, which indicates that the proposed impedance microprobe can be applied to the experimental research of electrical impedance/temperature property of biological tissue and can provide references for the monitoring of hyperthermia process based on electrical impedance technology.
