Revolutionary 3D Printing Technology Unlocks the Full Potential of Liquid Crystal Elastomers for Adaptive Materials
Researchers from Harvard, Princeton, and Brookhaven National Lab have developed a new method to control the properties of liquid crystal elastomers (LCEs) during 3D printing. LCEs are shape-morphing materials that change shape in response to heat, similar to muscle contractions and relaxations. The team’s breakthrough allows them to print LCEs with predictable and controllable alignment of molecules, enabling the creation of materials with tailored properties. This is achieved by using an X-ray characterization method to visualize molecular alignment during the printing process.

Adaptive Omni-Sensor Arrays Respond to Galactic Signals
Researchers at the Johns Hopkins Applied Physics Laboratory (APL) have developed a shape-shifting antenna that can dynamically adapt to different communications requirements. The antenna features a double spiral made of shape-memory alloy, which changes shape when heated or cooled, allowing it to operate effectively at frequencies ranging from 4-11 gigahertz. The idea was inspired by science fiction novels and was made possible by cutting-edge 3D printing techniques. The antenna’s shape determines its characteristics, such as frequency range, beam width, and polarization, making it a promising solution for reconfigurable antennas. The team was able to print a complex double spiral configuration and incorporate a copper wire to heat the antenna and switch between different shapes. The antenna can transition between a flat spiral and a cone shape in seconds, achieving a solid signal strength of approximately 5 decibels. The technology has promising applications in 6G wireless communication, where devices may need to operate over multiple frequency bands. The approach avoids the need for additional electronic components, but may have slower response times compared to metasurfaces.
