Wearable plant sensors hold tremendous potential for smart agriculture. We report a lower leaf surface-attached multimodal wearable sensor continuous monitoring of physiology by tracking both biochemical and biophysical signals the its microenvironment. Sensors detecting volatile organic compounds (VOCs), temperature, humidity are integrated into single platform. The abaxial attachment position is selected on basis stomata density to improve signal strength. This versatile platform enables various stress applications, ranging from water loss early detection pathogens. A machine learning model was also developed analyze multichannel data quantitative tomato spotted wilt virus as 4 days after inoculation. evaluates different combinations disease predicts that minimally three required including VOC sensors.
