This work reviews design aspects of liquid metal antennas and their corresponding applications. In the age of modern wireless communication technologies, adaptability and versatility have become highly attractive features of any communication device. Compared to traditional conductors like copper, the flow property and lack of elasticity limit of conductive fluids, makes them an ideal alternative for applications demanding mechanically flexible antennas. These fluidic properties also allow innovative antenna fabrication techniques like 3D printing, injecting, or spraying the conductive fluid on rigid/flexible substrates. Such fluids can also be easily manipulated to implement reconfigurability in liquid antennas using methods like micro pumping or electrochemically controlled capillary action as compared to traditional approaches like high-frequency switching. In this work, we discuss attributes of widely used conductive fluids, their novel patterning/fabrication techniques, and their corresponding state-of-the-art applications.

The Difference

Swimming motors navigating in complex fluidic environments have received tremendous attention over the last decade. In particular, liquid metal (LM) as a new emerging material has shown considerable potential in furthering the development of swimming motors, due to their unique features such as fluidity, softness, reconfigurability, stimuli responsiveness, and good biocompatibility. LM motors can not only achieve directional motion but also deformation due to their liquid nature, thus providing new and unique capabilities to the field of swimming motors. This review aims to provide an overview of the recent advances of LM motors and compare the difference in LM macro and micromotors from fabrication, propulsion, and application. Here, LM motors below 1 cm, named mini/micro/nano scale liquid metal motors (MLMTs) will be discussed. This work will present physicochemical characteristics of LMs and summarize the state-of-the-art progress in MLMTs. Finally, future outlooks including both opportunities and challenges of mini/micro/nano scale liquid metal motors are also provided.

Measurement And Control

Optical pyrometry is potentially a valuable technique for temperature measurement and control in gas turbines. However the problems associated with obtaining a clean signal interpretable as a metal temperature can be formidable. The difficulties are examined here in the light of more than 18 years’ involvement, by the author’s company, with turbine pyrometry. A number of “ground-rules” are formulated which, it is hoped, will be useful to new and prospective users of the method. Experienced users may find the perspective adopted valuable. Some possibilities arising from recent technical developments are highlighted. If certain “ground-rules” can be followed in design of the pyrometer and its installation then this model is trivial. If the rules are contravened the model rapidly becomes intractable. In fast (blade profiling) applications the finite bandwidth of the pyrometer system must be considered. In slow systems the “one-sided” nature of most optical noise cannot be ignored. Finally provision of an adequate optical signal and maintenance of a clean lens are obvious prerequisites.

Service Conditions

With the insistence of the Electricity Boards that Boiler manufacturers be responsible for installation of metal temperature measuring equipment, it is necessary that the companies should be in a position to implement this requirement. The report examines the performance of selected thermocouple attachments under simulated service conditions.
