Título: | Finite element simulation of microelectrodes for bio-impedance sensor applications |
Autor: | Olmo, Alberto CSIC ORCID; Yúfera, Alberto CSIC ORCID | Fecha de publicación: | 2010 | Editor: | Institute of Electrical and Electronics Engineers | Citación: | First International Conference on Sensor Device Technologies and Applications (SENSORDEVICES): 232-235 (2010) | Resumen: | Electrical models for microelectrode-cell interfaces are essential to match electrical simulations to real bio-systems performance and correctly to decode the results obtained experimentally. The accurate performance simulation of a microelectrode sensor to changes in the cell-electrode system, such as cell growth, enables the optimum microelectrode design process. We report the use of COMSOL quasi-static mode, contrary to other DC modes frequently used, including magnetic fields to calculate the bioimpedance of the system. A fully electrode-cell model has been built, and the effect of fibroblasts of different diameters on the simulated impedance of small microelectrodes (32-μm square) has been studied, in order to validate the model and to characterize the microelectrode sensor response to changes in cell size and density. | URI: | http://hdl.handle.net/10261/84064 | DOI: | 10.1109/SENSORDEVICES.2010.50 | Identificadores: | doi: 10.1109/SENSORDEVICES.2010.50 isbn: 978-1-4244-7474-5 |
