Realizace biopotenciálových elektrod pro měření elektrofyziologických signálů

Abstract

This thesis deals with the proposal and implementation of a biopotential electrode for measuring biopotential in plants. The biopotential electrode is made of alternative materials called conducting polymers. The theoretical part describes the basics of plant neurobiology (a discipline of science about the generation and propagation of potentials in plants), techniques for measuring electrical signals in plants, bioelectrodes and properties of selected conducting polymers. The aim of the experimental part is to propose and create electrodes, partly made of conducting polymers, which would access the much needed conductive connection for extracellular measurement of plant potentials. The functionality of the bioelectrodes is tested on Venus flytrap (Dionaea muscipula) plant.
