This paper presents an autonomous wireless biosensor node for in-vivo and real-time plant monitoring in crops. An organic electrochemical transistor nested in the plant stem is used to detect variations in the concentration of cations in the xylem sap. A battery life-time as long as four years was estimated in spite of the high bias current of the sensor and the long observation time frame, thanks to sensor duty cycling and signal post-processing combined with low-cost energy harvesting.

An organic electrochemical transistor nested in the plant stem is used to detect variations in the concentration of cations in the xylem sap. A battery life-time as long as four years was estimated in spite of the high bias current of the sensor and the long observation time frame, thanks to sensor duty cycling and signal post-processing combined with low-cost energy harvesting.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
