植物在地球上已经拥有了30多亿年的历史，以天然而强大的感知系统维系着地球的生态平衡。近年来科学家用植物的电信号传导作为电子产品的传感器，致力于发展可持续性的设计，目前在科研领域，对于植物感知机制研究的重视程度还不够，科普设计也相对较少。本文通过对植物感知机制的研究，介绍以向光性物理原理作为基础的科普交互装置设计，并总结了科普装置的设计方法。用新颖的科普载体和方式，使观众在科普过程中具有“主动性”，目的是在快速了解向光性原理的同时，强调隐藏于人们身边的植物感知能力，启发观众的科学思路。

Plants have a history of more than 3 billion years on earth, maintaining the ecological balance of the earth with natural and powerful sensing systems. In recent years, scientists have used the electrical signal conduction of plants as the sensor of electronic products to develop sustainable design. At present, in the field of scientific research, the degree of attention paid to the study on plant perception mechanism is not enough, and the design of popular science is relatively less. Through the research of plant perception mechanism, this paper introduces the design of science popularization interactive installation based on the principle of phototropism , and summarizes the design method of science popularization installation. With a novel carrier of popular science and design methods, the audience can have "initiative" in the process of popularizing science, the purpose is to quickly understand the phototropism, at the same time, to emphasize the plant perception ability hidden in people's side, in order to enlighten the audience's scientific thinking.
