When a plant is subjected to external stimuli other than light such as mechanical stress from wounding the plant, temperature variance, and watering disparity, the intercellular process within the plant will produce an electric potential signal in response to these external stimuli.
However, the rate of photosynthesis and respiration are influenced by other environmental factors such as water, the concentration of oxygen and carbon dioxide in the air and nutrient supply available in the soil. Both chemical processes induce the flow of electrons. It is a process of transforming the carbohydrate molecules from photosynthesis into energy for the plants. Respiration in plants, on the other hand, is a reversed process of photosynthesis. With such condition, a plant can generate a potential difference as much as 50mV. This phenomenon is triggered on the plant by the periodic changes of light and darkness from the light source. This process will cause the transport of electrons inside the plants, which creates a potential difference between the leaves and roots under exposure of light. Photosynthesis is a process used by plants to synthesize carbohydrate molecules from carbon dioxide and water via the usage of light energy, normally from the sun. The plant uses light to differentiate day and night via photoperiodism and to enable the generation of energy via photosynthesis. Plants are sensitive to light due to its photoreceptors, which can be categorized as phytochromes, blue/UV-A and UV-B photoreceptors.

This new source of energy from plants is renewable, pollution free and sustainable as long as the plant is alive. Certain plants can produce a continuous small amount of electrical power at both day and night, unlike solar power, which is only functional in the presence of light. Hence, apart from these existing technologies, this research would like to introduce the usage of living plants as another new renewable energy source to harvest micro-energy. These technologies had been well known and used to harvest micro-energy.

This phenomenon had opened up the opportunity for the development of energy harvesting technique from low power energy sources such as from the vibration via piezoelectric materials, bioenergy from organic compounds via microbial fuel cell, radio frequency (RF) signal via RF power harvester, thermal energy via thermo-electric generator (TEG) and light energy via solar photovoltaic cell.
