Content SummaryElectric Potential (EP) signals are produced in plants through intracellular processes, in response to external stimuli (e.g. watering, mechanical stress, light, acquisition of nutrients). However, wireless transmission of a massive amount of biologic EP signals (from one or multiple plants) is hindered by existing, battery-operated wireless technology and increased, associated monetary cost. In this paper, a self-powered, battery-less EP wireless sensor is presented that harvests near-maximum energy from the plant itself and transmits the EP signal tens-of-meters away with a single switch, based on inherently low-cost and low-power bistatic scatter radio principles. The experimental results confirm the ability of the proposed wireless plant sensor to achieve a fully-autonomous operation by harvesting the energy generated by the plant itself. Also, EP signals experimentally acquired by the proposed wireless sensor from multiple plants, have been processed using Non-negative Matrix Factorization (NMF), demonstrating strong correlation with environmental light irradiation intensity and plant watering. The proposed low-cost, battery-less “plant-as-sensor-and-battery” instrumentation approach is a first but solid step towards large-scale electrophysiology studies of important socioeconomic impact in ecology, plant biology, as well as precision agriculture. en
