Abstract

Human Body Communication (HBC) technique uses human body as communication channel for transferring various physiological data. Like humans, plants are also composed of different types of tissues with highly specialized functions. For feasibility study of electrical signal transmission through plant body; two pair of electrodes viz. one pair for the transmitter and one pair for the receiver involving stem of full Mangifera Indica plant by using capacitive coupling has been setup. The signal transmission through the different parts of stem of different thickness has been analyzed in time domain at 100 kHz. Different channel lengths have been used for capacitive coupling and different electrode distance has been used for galvanic coupling under similar environmental conditions at room temperature. Effect of positioning the ground electrode in both longitudinal and transverse directions with respect to signal electrode in galvanic coupling has also been investigated and reported in this paper.
