We vapor print conformal conjugated polymer electrodes directly onto living plants and use these electrodes to probe the health of actively growing specimens using bioimpedance spectroscopy. Vapor-printed polymer electrodes, unlike their adhesive thin-film counterparts, do not delaminate from microtextured living surfaces as the organism matures and do not observably attenuate the natural growth pattern and self-sustenance of the plants investigated here. On-demand, noninvasive bioimpedance spectroscopy performed with long-lasting vapor-printed polymer electrodes can reliably detect deep tissue damage caused by dehydration and ultraviolet A exposure throughout the life cycle of a plant.
我们将贴合共轭聚合物电极直接蒸镀到活体植物上，并利用这些电极通过生物阻抗谱来检测正在生长的样本的健康状况。与传统的压敏胶薄膜电极不同，蒸镀聚合物电极不会在植物生长过程中从微纹理的活体表面剥落，也不会明显阻碍所研究植物的自然生长模式和自我维持。利用持久的蒸镀聚合物电极进行按需、非侵入式生物阻抗谱检测，可以可靠地检测到整个植物生命周期中由脱水和紫外线 A 暴露引起的深层组织损伤。
