Abstract

We propose a convenient and easy method to harvest electric potential from plants based on streaming energy. Streaming potential and streaming current are well known phenomenon in the field of microfluidics. Plants also possess micron sized negatively charged XYlem and phloem conduits where ionic sap fluid move by virtue of plant pressure. We predict that the movement of ionic sap could cause a streaming potential difference between the upper and lower portions of the stem. Two 400 μm thick Ag/AgCl electrodes probes were implanted (one at near the root and the other near the shoot) and sealed with PDMS resin. A multichannel multimeter was employed to continuously monitor and record the potential difference across the two probes. Thus a clear understanding of the streaming potential in plant system can be obtained.
