Facile manufacturing of sub-mm thick CNT-based RC filters

Abstract

CNT-Based RC networks are described with the purpose of showing empirical findings on the influence of the interdigitated electrodes (IDE) spacing, the dispersant compound and the number of deposited layers, on the impedance magnitude and phase of the CNTs. Additionally, we propose use-cases for these networks, applying them to the realization of filters of second order with easily tunable cut-off frequency, and with the inherent advantages of CNTs and printed technologies, rendering them a prime choice for applications where thin and flexible second order filters are necessary.
