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

植物可穿戴传感器有可能提供植物生理信息的连续测量。然而，由于缺乏传统植物可穿戴传感器的接口适应性，对具有腺毛和蜡的植物进行稳定和高保真监测具有挑战性。在这里，受自适应绕组植物卷须的启发，开发了一种基于自适应绕组应变 (AWS) 传感器的集成植物可穿戴系统 (IPWS)，用于植物脉冲监测。IPWS由三个模块组成，即AWS传感器、柔性印刷电路和智能手机APP显示界面。作为关键元素，AWS 传感器可以自适应地包裹在番茄茎上。重要的是，借助蛇形图案的激光诱导石墨烯，AWS 传感器表现出出色的抗温度干扰能力，温度电阻系数为 0。17/°C。IPWS被证明可以稳定、高保真地监测植物脉搏，可以实时反映番茄植株的生长和水分状态。
