Liquid metal imbalance of the surface tension induces a pressure difference between the rear and the head, which produces a thrust to drive the droplet toward the head; at the same time, the hydrogen produced in the electrochemical reaction process also further raises the thrust. The discovery of this phenomenon laid the technical foundation for the development of intelligent motors, vascular robots, fluid pumping systems, flexible actuators and even more complex liquid metal robots. Liquid metal Liquid metal consists of alloys with very low melting points which form a eutectic that is liquid at room temperature. The standard metal used to be
Common external power supply USB 2.0 (non-SuperSpeed) data rates and 3 A (60 W at 20 V) of current. Such minimum-specification USB Type-C cables are sometimes referred to as "charge" cables because, for most mobile device battery charging applications, 60 W is more than sufficient and a higher data transfer speed is less important than minimizing cable cost and maximizing cable length. IEC 63002:2016 defines interoperability guidelines for external power supplies used with portable computing devices that implement IEC 62680-1-2:Universal Serial Bus Power Delivery Specification with the IEC 62680-1-3: Universal Serial Bus Interfaces for data and power-Common Components-Type-CTM Type-C Cable and Connector Specification.
