Flexible Sensors for Plant Disease Monitoring

Advancement in the flexible substrate led to the sensor fabrication, which offers light weight and low-cost sensors. Such sensors are very important to monitor the plant health on regular intervals and describe the germination of the plant microbial diseases. Numerous climatic and soil characteristics, including rainfall, soil moisture, leaf wetness duration, ambient temperature, and ambient humidity, are used to monitor plant disease. In this paper, we described the reported work for sensing the aforementioned parameters on the flexible substrates. The emphasis has been given on the fabrication of these sensors and their sensor transfer function such as sensitivity, response time, stability, and hysteresis.
