Light-Powered Robot Decontaminates on Water’s Surface

Facebook X LinkedIn Email
RIVERSIDE, Calif., Dec. 16, 2021 — Researchers at the University of California, Riverside have devised a sustainable solution to clean contaminants in open waters. The researchers have introduced a light-powered, floating, autonomous, soft robot that is fueled by vaporized water. The robot is called Neusbot, after “neustons,” a category of organisms that float on the top of water or live right under the surface. Neusbot can generate adjustable, mechanical oscillating movements — a capability that is essential for the robot to function in a controlled way. To achieve controllability, the...Read full article

    thin film
    A thin layer of a substance deposited on an insulating base in a vacuum by a microelectronic process. Thin films are most commonly used for antireflection, achromatic beamsplitters, color filters, narrow passband filters, semitransparent mirrors, heat control filters, high reflectivity mirrors, polarizers and reflection filters.
    hydrophobic
    Hydrophobic is a term used to describe substances or materials that repel or do not readily interact with water. The word hydrophobic comes from the Greek words "hydro," meaning water, and "phobos," meaning fear. Hydrophobic substances typically have nonpolar molecules or regions in their structure, which means there is an even distribution of charge. Water is a polar molecule, with oxygen attracting electrons more strongly than hydrogen. Hydrophobic substances are often nonpolar or have...
    positioning
    Positioning generally refers to the determination or identification of the location or placement of an object, person, or entity in a specific space or relative to a reference point. The term is used in various contexts, and the methods for positioning can vary depending on the application. Key aspects of positioning include: Spatial coordinates: Positioning often involves expressing the location of an object in terms of spatial coordinates. These coordinates may include dimensions such as...
    nanopositioning
    Nanopositioning refers to the precise and controlled movement or manipulation of objects or components at the nanometer scale. This technology enables the positioning of objects with extremely high accuracy and resolution, typically in the range of nanometers or even sub-nanometer levels. Nanopositioning systems are employed in various scientific, industrial, and research applications where ultra-precise positioning is required. Key features and aspects of nanopositioning include: Small...
