随着软性和柔性电子产品的使用越来越多，越来越需要开发基底材料，以减轻与合成基底材料的不可降解电子废物相关的潜在环境风险。为了解决这个问题，作者开发了一种新型的2D植物基质，称为“孢子基质”，它由非过敏性天然花粉制成。花粉颗粒具有双层结构，具有超坚韧的孢粉素外壁，并且通过生态友好的过程设计了柔软的纤维素内壁。以这种方式，可以制备容易获得的、经济的、可生物降解的和生物相容的微凝胶。这种微凝胶可用于创建各种灵活的形状，具有定制的机械，几何，电子和功能特性以及性能特征，如热，化学和机械稳定性和光学透明度。此外，作者在这里展示了由花粉微凝胶制成的柔性天然基底的不同应用，用于健康监测和可穿戴无线加热的电子设备。这项工作的结果指出了开发基于植物基材料的新型柔性绿色电子产品的机会，这些电子产品应用于可穿戴传感器，植入式设备和软机器人等应用。
With the increasing use of soft and flexible electronics, there is a growing need to develop substrate materials that mitigate potential environmental risks associated with non‐degradable electronics waste from synthetic substrate materials. To address this issue, the authors develop a novel, 2D plant‐based substrate termed “sporosubstrate”, which is made of non‐allergenic natural pollen. The pollen particle has a double‐layered architecture with an ultra‐tough sporopollenin exine, and a soft cellulose intine is engineered through an eco‐friendly process. In this manner, a readily available, economical, biodegradable, and biocompatible microgel can be prepared. This microgel can be used to create a variety of flexible shapes with customized mechanical, geometrical, electronic, and functional properties and performance characteristics such as thermal, chemical, and mechanical stability and optical transparency. Moreover, the authors demonstrate here different applications of the flexible natural substrate made of pollen microgel for use in electronic devices for health monitoring and wearable wireless heating. The results of this work point to opportunities for the development of a new class of flexible green electronics based on plant‐based materials in applications such as wearable sensors, implantable devices, and soft robotics.
