This article reports the imperceptible augmentation of living systems, such as human skin and plant epidermis, using organic bioelectronic fibres. The fibres, based on poly (3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS), are tethered directly onto biological surfaces through an orbital spinning technique, allowing for customization of fibre density, orientation, and modalities. This method minimizes environmental impact and preserves the biological functions and sensations of the host. The fibres can be used to create on-skin electrodes for electrocardiogram (ECG) and electromyography (EMG) signal recording, skin-gated organic electrochemical transistors, and augmented touch and plant interfaces. The fibres are also repairable, upgradable, and recyclable, making them sustainable for long-term use. The study demonstrates the potential of this approach in health management and environmental monitoring, with applications in human health and plant science.This article reports the imperceptible augmentation of living systems, such as human skin and plant epidermis, using organic bioelectronic fibres.
