The human quest for beauty is manifested in numerous body decoration fashions such as makeups, tattoos, and stickers. The ancient “kirigami” art offers a variety of choices for sticker‐type body beautification, whereby with simple cutting, complex networks potential use as microfluidic channels and stretchable materials can be fabricated. Inspired by the fish‐scale pattern and kirigami art, a fish‐like wearable biosensor is designed and fabricated. This highly stretchable, well‐aerated, disposable, and wearable fish sticker enables sweat collection, diagnostics, and motion monitoring. A structure of photonic crystals is integrated in the paper channels for fluorescence enhancement sensing of sweat lactic acid and urea, and a stretchable electronic paper network induced sensitive resistance changes during the movement. The sensor is amenable to a variety of applications, such as personal care and human–machine interaction. The combination of art and sensing also provides a pleasant‐looking solution for both health and beauty.

To investigate the daytime vs nighttime differences in intraocular pressure (IOP), aqueous humor dynamics, central cornea thickness, and blood pressure among a cohort of healthy volunteers. Methods: Thirty healthy volunteers (mean [SD] age, 57.0 [8.6] years) were enrolled in the study. Individuals underwent 1 daytime visit and 1 nighttime visit for the measurement of aqueous humor dynamics. Measurements included IOP by pneumatonometry, aqueous flow by fluorophotometry, outflow facility by fluorophotometry and tonography, uveoscleral outflow by mathematical calculation, central cornea thickness by pachymetry, and blood pressure by sphygmomanometry. Results between visits were compared by appropriate t test. Dependence of the pneumatonometer probe results on position was tested in enucleated rabbit eyes at set pressures and probe positions. Results: Compared with daytime seated IOP, nighttime seated IOP was reduced by 16%, whereas nighttime supine IOP was increased by 17% (PϽ.001 for both).

Reinforced concrete is widely used in civil engineering due to its outstanding mechanical properties and low cost. However, icing and corrosion on concrete-based facilities such as roads, dams, and bridges often cause safety issues. Superhydrophobic surface with completely water-repellent properties that are inspired by the lotus leaf in nature, has great potential to solve this problem, however, most state-of-the-art and commercial superhydrophobic coatings are expensive and weak in mechanical robustness for large-scale application on concrete. Here, we developed an inexpensive, non-fluorinated, and robust superhydrophobic concrete (S-concrete) coating with a contact angle of 160 ± 1° and sliding angle of 6.5 ± 0.5°. This coating had a high surface mechanical strength and retained superhydrophobicity after blade scratch for several times or sandpaper abrasion for 20 m distance. The robust S-concrete coating also had a good anti-icing ability, a low deicing force, and a high corrosion resistance, which is expected to be applied on roads, buildings, bridges, and many other concrete-based facilities in large scale for anti-icing and anti-corrosion purposes.
