Since 1970 we have been using solar energy calculators. So why can't the same concept apply to tablets? Ubiquitous Energy claims they can do it. According to MIT Technology Ventures, the Cambridge, Mass.-based company is developing a coating that coats the screens of tablets and e-readers to convert sunlight into electricity. The same organic matter can also transform building windows into photovoltaic power plants - other companies are also working on the development of this concept product. Ubiquitous's thin film converts the invisible light in the spectrum—ultraviolet light and infrared light—to electricity. It can also convert visible light into electricity. At present, the company is still in the research and development stage. Its products have not yet reached a high level of energy efficiency or transparency. According to reports, the company’s technology can only convert less than 2% of its light into electricity, and its transparency reaches 70%. Ubiquitous's goal is to achieve a 10% conversion rate. (Compiled by Tao Shuhua) The compression spring (compression spring) is a spiral spring which is subjected to pressure. It is usually made of a circular cross-section of material, and is also made of rectangular and multi-ply steel, the shape of compression spring is cylindrical, conic, convex and Concave, and a few non-circular. There is a certain gap between the circle and the circle of compression spring, when subjected to external load, the spring shrinks and deforms, storage of deformation energy. Compression spring introduction to compression spring introduction to compression spring characteristics of helical spring subjected to compressive pressure to external pressure provides resistance to external pressure application of household appliances to power equipment pressure spring compression spring parameter compression spring specification compression spring selection compression spring specification parameter compression spring design compression spring fixed mode compression spring calculation compression spring size specification table introduction compression spring (compression spring) is a helical spring subjected to compressive pressure, most of the materials used are circular in cross-section, and some are rolled in rectangular or multi-ply steel. The springs are generally of equal pitch. The shapes of compression springs are: cylindrical, conical, medium convex and medium concave, and a few non-circular, etc. , there is a certain gap between the circle and the circle of the compression spring. When the spring is subjected to external load, the spring shrinks and deforms, and the deformation energy is stored. Compression Springs provide resistance to external pressure. Compression Springs are generally metal wires with equal pitch winding and a fixed wire diameter. Compression Springs use multiple open coils to provide resistance against external forces, such as the weight of the wheel or the weight of the body on the mattress. That is, they push back against external pressure. Compression Springs are generally metal wires with equal pitch winding and a fixed wire diameter. In addition, there are conic compression springs, or conic and linear combination of springs. Compression Springs can be used to resist pressure and/or store energy, depending on the application area. Round wire is the most commonly used compression spring, but there are square, rectangular and special shapes of wire manufacturing compression spring. Wire Springs with compression springs are used for everything from home appliances to power equipment, motors, etc. because they are the desired type of spring. By the load acting on them or their ends being compressed, the compression spring is compressed by the design of the wire in an attempt to return the spring to its original shape so that the load is pushed back. Main application: medical respiratory equipment, medical mobile equipment, hand tools, home care equipment, shock absorption, engine valve spring. Production Design 1. Look at the actual product requirements to choose the spring material. 2. According to product requirements, determine the internal and external diameter of the spring, the number of effective turns, and the value range of wire diameter. 3. The relevant parameters are substituted into the design parameter formula.
