“…Focusing the attention on the working principle, Figure 1 shows a schematization of the plant and the transduction principle which will be used to measure the UV-A radiation. In particular, considering the recent studies, the Dimorphotheca ecklonis was successfully used as a living sensor for UV-A radiation measurements, and the mechanism hypothesis was linked to the photoexcitation of cryptochromes through processes involving electron transfer and flavin reduction [32]. Plant cryptochromes are UV/blue light photoreceptors that play a pivotal role in the growth, development, and stress responses of the plant [36].…”

“…The conversion principle, widely studied in terms of X-ray irradiation, heating procedure and enzymatic activities [31] was based on the modification of the metabolic processes of natural microorganisms within the soil as a function of the external measurand. In [32] authors propose a plant-based sensor for UV-A radiation measurements realized by using a Dimorphotheca ecklonis as a living sensor and, in this case, adopting weak invasive contacts through electrodes inside the soil. The transduction principle is based on biochemical actions of cryptochrome.…”

“…This manuscript improves the state of the art by presenting, for the first time, a sensor based on Sanseviera cylindrica to measure radiation in the band 350-400 nm and having the prerogative of being selfgenerating, simple, low-cost, non-toxic, biodegradable, environmentally friendly and mimetic in the perspective to achieve a gigantic step in the realization of the green economy. Compared to the previous paper [32], the presented manuscript represents an evolution of the research activity with the goal of developing better performing living sensors with more interesting features and exhaustive characterization, performances and influences. The features arouse interest both in the context of environmentally friendly devices and for applications that can span in the context of security, cultural heritage, smart home and smart agriculture.…”

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.
