“…Unlike elastomer‐supported rigid films, such as evaporated continuous metallic films, transfer printed silicon membranes, or carbon‐based materials, our elastic gold conductors are more resistant to cracks under strains due to interlocking effect of the embedment structure (Figure S3, Supporting Information). No evident cracks were observed up to 80% strain (Figure S4, Supporting Information).…”

Sensitive, specific, yet multifunctional tattoo‐like electronics are ideal wearable systems for “any time, any where” health monitoring because they can virtually become parts of the human skin, offering a burdenless “unfeelable” wearing experience. A skin‐like, multifunctional electronic tattoo made entirely from gold using a standing enokitake‐mushroom‐like vertically aligned nanowire membrane in conjunction with a programmable local cracking technology is reported. Unlike previous multifunctional systems, only a single material type is needed for the integrated gold circuits involved in interconnects and multiplexed specific sensors, thereby avoiding the use of complex multimaterials interfaces. This is possiblebecause the programmable local cracking technology allows for the arbitrary fine‐tuning of the properties of elastic gold conductors from strain‐insensitive to highly strain‐sensitive simply by adjusting localized crack size, shape, and orientations—a capability impossible to achieve with previous bulk cracking technology. Furthermore, in‐plane integration of strain/pressure sensors, anisotropic orientation‐specific sensors, strain‐insensitive stretchable interconnects, temperature sensors, glucose sensors, and lactate sensors without the need of soldering or gluing are demonstrated. This strategy opens a new general route for the design of next‐generation wearable electronic tattoos.

“…Recently, advanced assembly methods based on transfer printing have been developed to provide a powerful solution for the integration of high-performance optical filters onto a variety of unconventional substrates [78]. After the deposition of the filter layer on silicon or glass substrates, the transfer printing technique [79][80][81][82] was utilized to transfer these filter layers onto flexible substrate. The obtained optical filter exhibited good flexibility and high optical performances, with almost unaffected characteristics after bending.…”

Bio-photonic devices that utilize the interaction between light and biological substances have been emerging as an important tool for clinical diagnosis and/or therapy. At the same time, implanted biodegradable photonic devices can be disintegrated and resorbed after a predefined operational period, thus avoiding the risk and cost associated with the secondary surgical extraction. In this paper, the recent progress on biodegradable photonics is reviewed, with a focus on material strategies, device architectures and their biomedical applications. We begin with a brief introduction of biodegradable photonics, followed by the material strategies for constructing biodegradable photonic devices. Then, various types of biodegradable photonic devices with different functionalities are described. After that, several demonstration examples for applications in intracranial pressure monitoring, biochemical sensing and drug delivery are presented, revealing the great potential of biodegradable photonics in the monitoring of human health status and the treatment of human diseases. We then conclude with the summary of this field, as well as current challenges and possible future directions.

“…Although numerous theoretical and experimental investigations on mechanisms, [ 31,32 ] fabrications, [ 29,33–37 ] or applications of nanogap‐based SERS substrates, [ 5,38–40 ] have been conducted, the simultaneous realization of scalable manufacture and dynamically tunable responses from a flexible nanogap‐based SERS substrate remains a significant challenge, which hinders their development in both fundamental nanoscience and practical applications. In this work, on the basis of previous researches, [ 30,41 ] we developed a local‐cracking method to fabricate a flexible silicon nanogap array, with scalable production and controllable dimensions, as an additional option in the dynamically tunable SERS substrate for molecular sensing. Optimization of the geometrical designs for silicon ribbons will facilitate the local cracking with the highest yield of about 99.74%.…”

Surface enhanced Raman scattering (SERS), as a promising and convenient analytical tool for molecule sensing, has turned out to be one of the most important applications of plasmonic nanostructures. However, its large‐area production, controllability, and adjustability remain significant challenges because of the weak control over the fabrication and spatial arrangement. Herein, a silicon nanogap array‐based flexible plasmonic substrate is developed, with capabilities of large‐area production, controllable arrangement, and width of nanogaps, by utilizing the standard microfabrication platform, and the fabricated flexible plasmonic substrate is further explored for dynamically tunable SERS for molecular sensing. After experimentally and theoretically optimizing the geometric designs of precursors, a 90 × 90 silicon nanogap array (over 1 cm × 1 cm) with a yield of about 99.74% is achieved. SERS is realized by depositing Au films onto the silicon nanogap. Dynamically tunable SERS is demonstrated by the thermally induced local stretch or contraction of silicon nanogaps, where the key parameters including Raman enhancement and sensitivity of the molecular sensor can be conveniently adjusted. These presented results significantly expand the scope of engineering opinions for flexible plasmonic nanostructures, which have many envisioned applications especially for environmental monitoring and biochemical detection.
