PENA POLO, Franklin; TROSEL, Yanitza; SANCHEZ, Ivan  and  BRAMER-ESCAMILLA, Werner. Capacitive sensor to measure the order state of discrete objects. Rev. Fac. Ing. UCV [online]. 2014, vol.29, n.1, pp.133-138. ISSN 0798-4065.

This article describes the development of an electrical capacitance system to measure the structural order of an array of equally sized quasi-two dimensional objects. A measurement device was designed and built based on an AC capacitive measurement circuit. A system of discs was built such that the structural order could be varied between a cubic and a hexagonal packing. Measurements of the capacitance of the system were taken using electrodes of size comparable to the diameter of the discs. Experiments and theoretical predictions show a deviation of 0.23%.

Keywords : Capacitive sensor; Packing fraction; Ordering transition.
