“…[6][7][8][9][10] The growth enhancement of plants, which is an important topic in agriculture, has been studied using the nonthermal atmospheric-pressure plasma [8][9][10] and other methods such as those involving low-pressure plasmas, [10][11][12][13] plasma-activated water, [14][15][16] and pulsed electric field. [17][18][19][20] Most of these studies have reported an improvement in seed germination rate and=or an increase in plant length. Thus far, we have shown that atmospheric-pressure air plasma irradiation of seeds of Raphanus sativus (L.) (radish sprout) can induce continuous growth enhancement for weeks after their germination.…”

We have studied the effects of air nonthermal plasma irradiation of seeds of Arabidopsis thaliana (L.) on their growth from the beginning of cultivation to their harvest. Three minute plasma irradiation of dry seeds resulted in growth acceleration in all the growth stages. Compared with the control, the plasma irradiation led to an 11% shorter harvest period, a 56% increase in total seed weight, a 12% increase in each seed weight, and a 39% increase in seed number.

High-voltage technologies, including plasma, are used in agriculture and food processing applications. Repetitively operated, compact high-voltage power supplies with moderate peak power have been developed for controlling discharge plasmas and electric field distribution for agricultural and food processing applications. These applications are mainly based on the biological effects of a spatially distributed electric field and the chemically active species produced by the plasma. The intense pulse electric fields (PEFs) that have biological effects are caused by applying pulse voltage between the electrodes. When the applied voltage exceeds the corona discharge criterion, discharge plasmas that produce free radicals, UV radiation, an intense electric field and shock waves are generated by the accelerated electrons within the intense electric field in a gas or liquid medium. Different high voltages and plasmas may have different biological effects on substrates via the electric field and reactive species. For instance, intense electric fields form pores on the cell membrane (i.e. electroporation) or influence the nucleus. The agricultural applications of plasma are categorized as seed germination promotion, plant growth acceleration, the inactivation of bacteria in soil and liquid hydroponic media, and the promotion of fruit-body formation such as in mushrooms and fruits in the pre-harvest phase. In the postharvest phase, maintaining the freshness of agricultural products is important for a sustainable food supply chain. High-voltage and plasma technologies can contribute to maintaining freshness by decontaminating the air and liquid in agricultural products storage containers. In the food processing phase, an intense PEF can be used to extract juice, nutritional agents and antioxidant metabolites such as vitamin, carotenoids and polyphenols from fruits and vegetables. Some foods and liquors are made by fermenting a food substance. Fermentation is a metabolic process enabled by yeast and bacteria, the activity of which can be controlled by an intense electric field.

Plants display physical displacements during their growth due to photosynthesis, which converts light into chemical energy. This can be interpreted as plants acting as actuators with a built‐in power source. This paper presents a method to create plant robots that move and perform tasks by harnessing the actuation output of plants: displacement and force generated from the growing process. As the target plant, radish sprouts are employed, and their displacement and force are characterized, followed by the calculation of power and energy densities. Based on the characterization, two different plant robots are designed and fabricated: a rotational robot and a gripper. The former demonstrates ground locomotion, achieving a travel distance of 14.6 mm with an average speed of 0.8 mm h−1. The latter demonstrates the picking and placing of an object with a 0.1‐g mass by the light‐controlled open‐close motion of plant fingers. A good agreement between the experimental and model values is observed in the specific data of the mobile robot, suggesting that obtaining the actuation characteristics of plants can enable the design and prediction of behavior in plant robots. These results pave the way for the realization of novel types of environmentally friendly and sustainable robots.
