“…Polymeric soft substrates with periodic nanostructures have the potential to be important components of many emerging technologies, including paper-like displays, 1 electronic eyes, 2 conformable skin sensors, 3 smart surgical gloves, 4 and health monitoring devices, 5 due to their ease of processing, mechanical flexibility, and highly controllable physicochemical properties. It has been reported that thin film contraction under external mechanical stress can be used to create periodic patterned features on the surface of thin silica or metal films on elastic substrates.…”

This paper reports a simple and versatile technique for generating highly controllable sinusoidal nanostructures on the surface of poly-(dimethylsiloxane) (PDMS). The sinusoidal features were generated by oxidizing PDMS slabs with oxygen plasma, then stretching them by wrapping around a cylinderical surface, and finally allowing them to relax. The wavelength and amplitude could be finely controlled by varying the fabrication conditions such as duration of oxidation, diameter of the glass cylinder, duration of stretching, thickness of the PDMS slabs, and temperature during the second hardening process. The varied trends of the buckling patterns were characterized by using an atomic force microscope.

“…Thus, the problem of continuously monitoring and detecting a thermal excitation on very large areas (100 m 2 ) with high resolution (1 cm 2 ) is one that has remained largely unsolved. [3,4] We present a new methodology for measuring spatially resolved temperature information on large areas with high spatial resolution and low cost. Underlying our approach is a new fiber material that senses heat along its entire length and generates an electrical signal.…”

Thermal sensing and thermography yield important information about the dynamics of many physical, chemical, and biological phenomena. [1,2] Spatially resolved thermal sensing enables failure detection in technological systems when the failure mechanism is correlated with localized changes in temperature. Indeed, IR-imaging systems have become ubiquitous for applications where line-of-sight contact can be made between the measured object and the camera lens. Nevertheless, many critical applications do not lend themselves to radiative IR imaging because of the subterraneous nature of the monitored surface, spatial constraints, or cost considerations. The recent challenge of monitoring the skin temperature beneath the thermal tiles on the space shuttle represents a good example in which high-spatial-resolution information is required on very large surface areas but which cannot be obtained using traditional thermal-imaging systems. Thus, the problem of continuously monitoring and detecting a thermal excitation on very large areas (100 m 2 ) with high resolution (1 cm 2 ) is one that has remained largely unsolved. [3,4] We present a new methodology for measuring spatially resolved temperature information on large areas with high spatial resolution and low cost. Underlying our approach is a new fiber material that senses heat along its entire length and generates an electrical signal. This is in contrast to all previous work on thermal sensing using fibers, which require the use of optical probing signals. [5] Although the fibers are produced by thermal drawing, they contain a set of materials that have not been traditionally associated with this process. The use of thermal drawing guarantees the production of extremely long fibers, while the innovation in preparation of the preform and choice of materials allows the incorporation of novel functionalities. Specifically, both thermal and electrical functionalities are obtained in the fibers studied in this communication, while optical and optoelectronic functionalities in alternative designs have been obtained previously and are reported elsewhere. [6,7] The fibers are produced by a novel fabrication technique that enables the incorporation of materials with widely disparate electrical and thermal properties in a single, macroscopic, cylindrical preform rod, which subsequently undergoes thermal drawing to give solid-state microstructured fibers with high uniformity. The main requirements in the materials used in this preform-to-fiber approach are as follows: 1) the component which supports the draw stress should be glassy, so as to be drawn at reasonable speeds in a furnace, with self-maintaining structural regularity; 2) the materials must be above their respective softening or melting points at the draw temerature to enable fiber codrawing; and 3) the materials should exhibit good adhesion/wetting in the viscous and solid states without delamination, even when subjected to thermal quenching. According to these requirements, we identified suitable semiconducting, ins...
