With billions of years of nature evolution, biological systems have developed many elegant sensing structures with superior sensing performance. Inspired by such biological sensing systems, different man-made sensors have been designed and fabricated to match or surpass the performance of those biological counterparts. In this presentation I will discuss our effort in design, fabrication, and characterization of bioinspired nanostructured sensors for energy and environmental detection. In particular I will discuss the nanosensors for thermal energy detection. The detection of thermal energy is critical in many industrial applications, including the thermal energy distribution within both steam turbine and gas turbine, the thermal energy signal within the component of aerospace vehicles, and the thermal energy distribution within a solar-thermal energy conversion system (1). With the critical roles played by the thermal detection technologies in a growing range of applications, the need of portable and high performance thermal sensing systems drives up the technology development (2, 3). We explored an alternative thermal detection mechanism that is based on the desorption of vapor molecules from the butterfly-inspired nanosensor under the stimulation of incoming thermal radiation, and demonstrated the use of such stimulated desorption for both broadband and wavelength selective thermal radiation detection. This new detection mechanism enables more than an order of magnitude of improvement in both the response of relative reflectance and also the signal-to-noise ratio at the maximum heat-sink-free response speed. The stimulated desorption also provides the opportunity to achieve the wavelength selective thermal radiation detection due to the wavelength selective thermal absorption of the molecules. Based on the similar approach, a self-powered thermal radiation nanosensor that can convert thermal radiation into electric signals was also demonstrated. Besides the thermal energy detection, these bioinspired nanosensors can also be used for the detection of other environmental targets, including both vapor detection and noise detection (4, 5). Such detection approach thus offers a platform for a range of high performance sensing systems, including energy, environmental, chemical vapor, and biological sensing systems.
