Abstract: The present disclosure generally relates to a stretchable anti-fogging tape (SAT) that can be applied to diverse transparent materials with varied curvatures for persistent fogging prevention. The SAT comprises three synergistically-combined transparent layers: i) a stretchable middle layer with high elastic recovery to keep transparent materials tightly bound; ii) an anti-fogging top layer to impart hydrophilicity to transparent materials; and iii) an adhesive bottom layer to form robust yet reversible adhesion between transparent materials and SATs. The SAT can be configured to have water condensate form a predominantly continuous film thereon in response to a high humidity environment At least two applications are demonstrated, including the SAT-adhered eyeglasses and goggles for clear fog-free vision, and the SAT-adhered condensation cover for efficient solar-powered freshwater production.

Abstract: Photo-detectors disclosed include at least one of a thin film or a heterostructure of photo-sensitive material and a pair of Ohmic contacts coupled to the at least one of the thin film or the heterostructure. The at least one of the thin film or the heterostructure is configured to be under a strain gradient to induce shift current flow within the material to perform photo-detection in a frequency range that includes a mid-infrared frequency range. The photo-detectors provided for can include a variety of configurations, such as a lateral configuration or a vertical configuration, and can operate in self-powered and negative illumination regimes. Associated methods are also provided, which can include inducing a strain gradient and performing photo-detection in a frequency range that includes a mid-infrared frequency range.
