Electricity Derived from Plants

Harnessing Plant Bioelectricity through Prickly Pear as Botanical Batteries

“…For more than a century, reports of electrical potential variations along plant apoplast have been made. The power recorded in earlier studies on plant harvesting was in the nW (Nano watt) range with a few hundred mV (Medium Voltage) of open circuit voltage and close to uA (Microampere) of short circuit current, (Chao et al 2017). Due to the unique composition that most plant leaves naturally have; certain leaf structures can transform mechanical forces applied at the leaf surface into electrical energy.…”

Plant electrophysiology: bibliometric analysis, methods and applications in the monitoring of plant-environment interactions

“…This method produces wounds in the plants that can alter the external stimulus measurements. Different electrodes have been reported as thin metal tips made of platinum (Pt) or Ag/AgCl wires have been reported as thin metal tips made of platinum (Pt) or Ag/AgCl wires [49,[69][70][71]46], metal probe [72], Ag/AgCl electrodes from Teflon-coated silver wires [73], silver wires (0.2 mm in diameter) [62,63,9], microelectrode filled with 100 mM KCl [64], wires (50/im diameter 10% iridium-platinum) [66], reversible Ag/AgCl electrodes prepared with AgCl on 5mm long silver wire tips without Teflon coating in a 0.1 MKCl aqueous solution [61], Ion-selective microelectrodes describe by [74]. In [16], two types of electrodes were used: glass microelectrodes from boro-silicate glass (Hilgenberg, Malsfeld, Germany) filled with 3 mol/L KCl solution, and conventional Ag/AgCl electrodes made of silver wires 0.2 mm in diameter coated with AgCl.…”

“…In other reported studies, the polarity of the plant tissue has been identified, in order to obtain a sustainable energy source. In the study of [72], they identified polarity based on plant growth and noted that by assembling branch sections in series or parallel arrangements, it is possible to increase the voltage or current depending on the arrangement. The power generation of the plant was also the object of study of [119], in the reported work, a self-powered wireless system was developed, which collects the energy of the plant itself for its operation and transmits the signal generated by the plant with stimuli of electricity and water, the study was carried out on avocado plants.…”
