Project: Characterization of Plants Extracellular Signals
We have developed a CMOS-based microelectrode array (MEA) featuring high-density electrodes,
i.e., 11´016 metal electrodes and 126 on-chip circuitry channels, each of which includes recording
and stimulation electronics. This device enables extracellular electrical-activity recordings at subcellular spatial resolution and microsecond temporal resolution.
In plants, some cells are electrically excitable and active, releasing and propagating action potentials
(APs), which may affect important physiological processes, such as photosynthesis and respiration.
Moreover, electrical signals are believed to play a central role in intercellular and intracellular
communication at all levels of evolution from algae to higher plants
