The electronics of tomorrow will be imperceptible and will form a seamless link between soft, living beings and the digital world. This new form of ultra-conformable electronics places severe physical requirements on the active components that constitute modern foil-like electronic systems. Weight and flexibility become key figures of merit for large area electronics such as robotic skin, as they critically influence the mechanical response and perception of the artificial sensory system. With less than 2 μm total thickness, imperceptible electronic foils are light (≈3-4 g m- 2) and unmatched in flexibility, they are operable with radii of curvature below 5 μm, yet highly durable and withstand severe crumpling without any performance degradation. These are prerequisites for intimate contact with soft, biological tissue or organs and complex, arbitrarily shaped 3D free forms that enable applications spanning medical, safety, security, infrastructure, and communication industries.
This talk introduces a technology platform for the development of large-area, ultrathin and lightweight electronic and photonic devices, including organic solar cells[1], light emitting diodes[2], active-matrix touch panels[3], implantable organic electronics[4], imperceptible electronic wraps[5] and “sixth-sense” magnetoception[6] in electronic skins. Solar cells, less than 2 μm thick, endure extreme mechanical deformation and have an unprecedented power output per weight of 10 W/g and more. Highly flexible, stretch-compatible polymer light emitting diodes for display applications and ambient lightning conform to arbitrary 3D free-forms and provide electrical functionality in yet unexplored ways through simple and cost-effective fabrication. Tactile sensor arrays based on active-matrix organic thin film transistors can be operated at elevated temperatures and in aqueous environments as an imperceptible sensing system that ensures the smallest possible discomfort for patients requiring medical care and monitoring. E-skins with GMR-based magnetic field sensors equip the wearer with an unfamiliar sense that enables perceiving of and navigating in magnetic fields. These large area sensor networks build the framework for electronic foils and artificial sensor skins that are not only highly flexible but become highly stretchable and deployable when combined with engineered soft substrates such as elastomers, shape memory polymers or tissue-like hydrogels.
