A preliminary electrobiophysical study on electrical polarity detection ability of the excitable plant Mimosa pudica: A probable biosensor of electrical polarity

---

Abstract

J.C. Bose, for the first time had established that excitable plant tissue exhibits the similar excitatory response to polar electrical currents which are seen in excitable animal tissues. Recent studies have also reported electrical polarity sensing ability of the sensitive plant Mimosa. In this backdrop, the present electro biophysical study aims at understanding the characteristic response of Mimosa to polar electrical currents and the effect of variable intensities of the stimulating DC voltage on the characteristic response of the plant. For the study, a compact and customized electrical polar stimulator apparatus has been developed in the laboratory
