• Cotton fabrics were coated with Polyaniline (PANI), Polypyrrole (PPy) and with combinations of these two conducting polymers (double layer) • Coated cotton fabrics were used as sensors to collect electrical response from Venus Flytrap plant • PANI and PPy are regarded as mixed conductors – having both ionic and electronic conduction [1-3] • Paradigm of the use of conducting polymers in monitoring of plant neurobiology • The method used is compared with the standard method – Ag/AgCl electrode with conducting gel Department of Cybernetics and Biomedical Engineering http://bmeng.vsb.cz

Method • (A) Clip electrode with coated cotton fabric • (B) Non-polarizable Ag/AgCl surface electrode connected to the protruding strip of coated cotton fabric • (C) Reference electrode • (D) Plastic stick used for stimulation


Results – Series of action potentials, PPy+PANI

• All cotton fabrics coated with PANI, PPy and their combinations have been able to collect and transfer the electrical response Department of Cybernetics and Biomedical Engineering http://bmeng.vsb.cz

Conclusions • No significant differences among fabrics coated with different conducting polymers – PANI, PPy, PANI+PPy, and PPy+PANI were observed: • The trap (leaf) is a three-dimensional structure, contact area strongly varied during measurements from one another • Even the lowest conductivity (single layer) is high enough for the recording of electrical signals in plants

• Cotton fabrics coated with conducting polymers are definitely comparable to the standard method: + + + + -

Very good results at both single and series response monitoring No need of conducting gel No risk of tissue damage caused by the conducting gel Simple and cost-effective preparation process Slightly lower signal to noise ratio


Electrosurgical tools for non-linear cuts • Based on stadardized tools • Innovative shape of the tool = less of damaged tissue of liver
