Abstract
Capacitive transduction is investigated for use in a liquid crystal (LC) based sensors with potential applications to biological systems. The theory for tracking the average molecular orientation of a partially disordered liquid crystal film via capacitive transduction in an inhomogeneous, anisotropic media is presented. The sensitivity for the sensor at different alignment is discussed. Both the experimental and calculated values for fringing capacitance of a selected structure are presented.
