An integrated and robust plant pulse monitoring system based on biomimetic wearable sensor

Abstract Plant wearable sensors have potential to provide continuous measurements of plant physiological information. However, stable and high-fidelity monitoring plants with glandular hairs wax is challenging, due lacking interface adaptability conventional sensors. Here, inspired by adaptive winding tendrils, an integrated system (IPWS) based on strain (AWS) sensor for pulse was developed. The IPWS consists three modules, i.e. AWS sensor, a flexible printed circuit, smart phone APP display interface. As the key element, can adaptively wrap around tomato stem. Importantly, serpentine-patterned laser-induced graphene, exhibits excellent resistance temperature interference coefficient 0.17/°C. demonstrated be pulse, which reflect growth water state in real time.
