“…It should be noted that the choice of a specific plant and soil is crucial during the implementation of the living sensor. The sensing properties of plants are extensively studied in the context of plant biology and various studies have been conducted in the context of electrophysiology [25], and, as shown in [26], the adoption of plants as living sensors can be considered as a suitable green paradigm in the instrumentation and measurements context. In [27], authors investigate electrical signals in long-distance communication in plants giving particular emphasis to action potentials.…”

This research activity concerns the development of a sensor based on Sansevieria plants to measure UV-A radiation.The proposed approach is based on soils and plants together with the metabolic processes and bacterial activities involved in such organisms. This generation of devices aims to overcome siliconbased solutions that cause environmental pollution with CO2 emissions during manufacturing and issues of nonbiodegradability and toxicity at the dissemination or end of life phases. The sensor here studied and characterized presents no CO2 emissions during the production, considering the absence of manufacture and foundries processes, and it is also capable to meet the zero-CO2 condition by reducing the amount of carbon dioxide already present in the environment through natural photosynthetic processes. The living sensor based on the Sansevieria and its working principle is studied for the first time in literature, together with the analysis of radiation in the bandwidth of 350-400 nm, the metrological characterization, the features and influences analysis. The results highlight the suitability of the Sansevieria as a self-generating, battery-less sensor based on the metabolic processes in the living system, soil and plant, as a function of the measurand. It is worth noting that the approach followed here has the prerogative of being simple, low-cost, non-toxic, biodegradable, environmentally friendly, and mimetic with a perspective of achieving a huge jump in the development of green measuring systems.
