The unmatchable capability of living cells to fabricate complex structure starting from simple building blocks offers new paradigms to seamlessly integrate new electronic structures into the living matter, creating new hybrid devices. We exploited this potential in a simple tissue-like organism, the freshwater polyp Hydra vulgaris, and here we provide an overview of recent and on-going results obtained with this model together with our methodological approaches ranging from behavioural to optical, spectroscopical, and electrical characterization. By simple exposure to conjugated oligomers we show the capability of Hydra to fabricate new electronically conducting and electrochemically active microstructures in specific cell types [1]. In another case, fluorescent and conductive microfibers embedded into the tentacle tissues were produced starting from oligothiophene compounds, showing the feasibility to use these organisms as biofactories to fabricate and to test novel bioelectronic interface [2]. Tissues with integrated biocompatible electronics, manufactured in vivo in localized regions, may inspire new devices to manipulate biological functions by adding or augmenting conductivity in physiological or pathological contexts with spatiotemporal control, paving the way to new bioengineering concepts.
