Application of Article 30, Paragraph 2 of the Patent Law 1. Type of disclosure: Academic presentation Date of disclosure: March 16, 2023 (16.03.2023) Title of disclosure: Long-term remote monitoring of plant physiological responses using ultra-small sensors Place of disclosure: 64th Annual Meeting of the Japanese Society of Plant Physiologists, Tohoku University, Miyagi Prefecture 2. Type of disclosure: Academic presentation Date of disclosure: March 18, 2023 (18.03.2023) Title of disclosure: Development of a plant leaf IoT monitor using a color sensor and continuous observation through long-term outdoor operation Place of disclosure: 70th Spring Meeting of the Japan Society of Applied Physics, Sophia University, Tokyo This invention relates to a support structure and system. This invention claims priority based on Japanese Patent Application No. 2022-109088, filed in Japan on July 6, 2022, the contents of which are incorporated herein by reference. Technologies for measuring and detecting real-time physiological changes in plants enable efficient remote observation in agricultural fields such as crop cultivation management and environmental measurements in hard-to-reach areas like forests. For long-term observation of plant leaves, it is important that the device does not damage the leaves, does not inhibit physiological responses such as photosynthesis, and that the observation device is robust enough to be attached. For example, Patent Document 1 discloses a plant sensing device that is attached to a plant leaf to acquire close-up images of the leaf surface. This plant sensing device comprises a light source part having a surface-emitting light source, a sensor part having an image sensor and a fiber optic plate (FOP) arranged on its imaging surface, and a part fixing means for fixing both parts to the surface of the plant leaf by pressing them against the plant leaf surface with the light-emitting surface of the light source part and the surface of the FOP of the sensor part facing each other, with the plant leaf in between.

Embodiments of the present invention will be described below with reference to the drawings. In the following embodiments, a support structure for non-destructively measuring real-time physiological changes in plants will be described. In the drawings used in the following description, the scale of each component has been appropriately changed to make each component recognizable. <Support structure> Figure 1 is a perspective view showing an example of the support structure 1 of the embodiment attached to a plant 10. For example, the plant 10 is a terrestrial plant that grows on land. However, the plant 10 is not limited to a terrestrial plant. For example, the plant 10 may be an aquatic plant that grows in water or on the water surface. For example, the support structure 1 can be applied to any plant. The plant 10 comprises branches 11 (e.g., stems) that branch off from the trunk, and a plurality of leaves 12 provided on the branches 11. In the example shown in the figure, three leaves 12 are provided at the tip of the branch 11. In the example shown in the figure, the support structure 1 is provided along one of the three leaves 12 (e.g., the largest leaf) and one branch 11. The support structure 1 is a structure for positioning acquisition units 2A, 2B, and 2C, which acquire information about the state of the leaves 12 of a plant 10 or the surrounding environment, near the leaves 12. The support structure 1 comprises a
