Abstract:A novel tattooable, ultrathin, green organic light‐emitting diode (OLED) fabricated on top of commercial temporary tattoo paper, is demonstrated. The transfer mechanism relies on dissolution of the sacrificial layer typically incorporated in paper‐tattoos. The ready‐to‐use device can be stored on the tattoo substrate and released on the target surface at a later time, simply by a slight wetting of the tattoo paper with water. This approach provides a quick and easy method of transferring OLEDs on virtually any… Show more

“…There are methods whereby our access to our internal structures can be made wholly non-invasive—such as through the oral or nasal cavities—so it cannot be stated that no such avenue exists presently. Insofar as efforts continue to be made in the direction of health “wearables” or “insideables” [ 20 , 21 , 22 , 23 , 24 ], there will be a public desire to ensure that considerations are being made for the minimisation of damage through the use and maintenance of devices and implements that must enter the body through the ECM and other tissues or are otherwise implanted for extended periods. Even for “necessary” intravenous fluid or drug administration in clinical settings, let us not forget that patients may believe any implement entering their body is “invasive” even if it is not clinically understood to be so to practitioners, legal experts, and ethicists.…”
Much research has been conducted on how patients may be served through new advances in perioperative anaesthetic care. However, adaptations of standardised care methodologies can only provide so many novel solutions for patients and caregivers alike. Similarly, unique methods such as nanoscopic liposomal package delivery for analgesics and affective numbing agents pose a similar issue—specifically that we are still left with the dilemma of patients for whom analgesics and numbing agents are ineffective or harmful. An examination of the potential gains that may result from the targeted development of nanorobotics for anaesthesia in perioperative care will be presented in this essay to help resolve this pending conflict for the research community. This examination should therefore serve as a “call to action” for such research and a “primer” for those for whom the method’s implementation would most directly impact.
“…Indeed, organic materials permit the achievement of ultrathin functional nanosheets that are intrinsically soft, flexible and transparent. Moreover, since they can be made solution processable, they are compatible with several large areas and cost-efficient deposition techniques, such as printing 12 – 15 , and require low processing temperatures 16 – 18 .…”
Recent advancements in the field of electronics have paved the way to the development of new applications, such as tattoo electronics, where the employment of ultraconformable devices is required, typically achievable with a significant reduction in their total thickness. Organic materials can be considered enablers, owing to the possibility of depositing films with thicknesses at the nanometric scale, even from solution. However, available processes do not allow obtaining devices with thicknesses below hundreds of nanometres, thus setting a limit. Here, we show an all-organic field effect transistor that is less than 150 nm thick and that is fabricated through a fully solution-based approach. Such unprecedented thickness permits the device to conformally adhere onto nonplanar surfaces, such as human skin, and to be bent to a radius lower than 1 μm, thereby overcoming another limitation for field-effect transistors and representing a fundamental advancement in the field of ultrathin and tattoo electronics.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
