Bioelectronic transducers

- for plant health and environmental monitoring -

Circadian rhythms in plants are self-sustained oscillations in the physiology, morphology or activity of plants, with an about 24 h period under natural illumination. Two, and only two, characteristics are recognized as belonging irrefutably to the biochemical oscillator which controls the rhythms: the length of the period and the phase relative to an external time reference.
Typical examples are the sleep movements of leaves, the dynamics of the hydric balance or of the gas exchange between leaves and their environment ( more about circadian rhythms ... )

The main idea is to develop electronic devices which are able to monitor the dynamics of some physiological parameters of plants in order to detect perturbations induced by changes in their physical or chemical environment.

Research is focussed on several topics, ranging from plant tissue - electronic circuits interface design and bioelectrical activity monitoring, to data processing and environmental monitoring devices development.

Applications: hydric stress detection, climatic changes investigation through long-term hydric balance monitoring in trees, pollution detection through photosynthesis monitoring in aquatic plants, etc.
