Scientists at the Massachusetts Institute of Technology in the United States have recently developed a deformed material made of wax and foam that can be easily deformed.
According to foreign media reports, the liquid deformation robot T-1000 that appeared in Terminator 2 20 years ago has been freshly remembered. At present, this terrible technology is about to become a reality. Scientists at the Massachusetts Institute of Technology have recently developed an advanced technology. The deformed material allows the robot to change between hard and soft states.
This latest material is expected to develop a new generation of robots, because it is a mixture of wax and foam material structure that can be deformed to different shapes. In the "Terminator 2: The Last Days" filmed in 1991, the T-1000 robot is made of liquid metal and can be deformed into a liquid state, drilled into a sealed space, and repaired when it is damaged.
Anette Hosoi, a professor of mechanical engineering and applied mathematics at the Massachusetts Institute of Technology, developed this latest material and was able to realize the robot's special capabilities at a low cost. This material can also be used to make deformable surgical robots that will move through the body and reach specific areas without damaging any organs and tissues.
The latest research report was published in the recently published "Journal of Polymer Materials and Engineering", and "deformation robot" can also be used to search for rescue missions and drill into gravel to find survivors. To create a material that can switch between wet and stiff conditions, the researchers covered a wax lattice with a lattice structure. They chose the foam because it can compress into a small part of its original volume. Once the pressure is released, The original shape will be restored.
The wax coating can transform from a hard outer layer to a soft surface with moderate heating. Professor Hawthorne pointed out that placing a wire in each foam-coated frame allows it to be energized to heat and melt the surrounding wax coating. Re-closing the current again will cool the material down to its original state of hardness.
In addition to the transformation between states, heating the wax coating in this way can also repair any structural damage. Professor Hawthorne explained that this material has the ability to heal itself, so when the wax coating cracks, you can heat and then cool, This structure will restore the original state.
To build this material, the researchers simply placed the polyurethane foam in a molten wax and then compressed the foam to ensure it absorbed enough wax. The research report co-author Nadia-Chan said: "Many invented materials are very expensive, but the new deformed material is completely different. It uses only low-cost polyurethane foam and some wax liquid."
Optical Microscopy
In optical microscopy different filters are used to improve contrast and emphasize specific features based on material properties. This can be achieved with magnifications typically ranging from 2.5 times up to 1,000 times. In materialography, reflected light is the most commonly used type of light optical microscopy. Transmitted optical microscopy is also used, but mainly for mineralogy specimens.
Stereo Optical Microscopy
The stereo microscope is an optical microscope variant, designed for low magnification observation of a specimen, using the light reflected from the specimen surface.
Scanning Electron Microscopy
A scanning electron microscope (SEM) is a type of electron microscope that produces images of a specimen by scanning the specimen surface with a focused beam of electrons. The electrons interact with the atoms in the specimen, producing various signals that can be translated into information about the surface topography and the composition of the specimen.
Transmission Electron Microscopy
Transmission electron microscopy (TEM) uses a beam of electrons transmitted through an ultra-thin specimen and that interacts with the specimen as it passes through it. Generated signals can be translated into various types of information, including information on the type and orientation of individual crystals.
