| The capacitive sensing in a homogeneous single layer of liquid crystal using chemical and biological sensors is demonstrated. Our innovation is to use capacitive transduction sensing instead of optical transduction sensing which was used in experimental papers about liquid crystal based chemical and biological sensors (Science, 2001) by Professor Abbott at the University of Wisconsin.;In the simulation, using the difference equation for the Finite Difference Method, the boundary conditions by three conductors are discussed. Therefore, the computation for voltage potential graph, electric field graph and capacitance graph are provided. The simulation results show the possibility of capacitance transduction. The empirical results are represented with the microfabrication processes. The experimental data sheet is shown to prove the simulation results. Using the simulation and experiment results, the proof of the capacitive transduction technique is shown. |
