激情快播 and the University of Florida are receiving $1.2 million over two years from Defense Advanced Research Projects Agency (DARPA) to develop a miniature system capable of levitating a large mass with exceptional stability.

The funding comes from DARPA鈥檚 Trapped Accurate microSystems (LeviTAS) program, which aims to explore the feasibility of replacing a spring anchor with a levitation system to trap a mass roughly the size of a sugar cube within a volume about the size of a Rubik鈥檚 cube for use in defense systems.

The specific project awarded to 激情快播 and UF is called Full Levitation In MAgnetically Stabilized Systems (FLi-MaSS), and is one of eight teams selected as part of DARPA鈥檚 LeviTAS program.

Jaesung Lee, an assistant professor in 激情快播鈥檚 Department of Electrical and Computer Engineering, and Philip Feng, a professor in UF鈥檚 Department of Electrical and Computer Engineering and graduate faculty Department of Physics, are collaborating on the project.

Through their FLi-MaSS project, Lee and Feng are hoping to transform levitated systems by achieving unprecedented stability and performance metrics crucial for next-generation navigation sensors that may be applied for defense and civilian uses.

The team plans to achieve this through diamagnetic levitation or a 鈥渉overing鈥 effect. Diamagnetic materials are materials that are repelled and stabilized by a magnetic field.

Lee and Feng will also experiment using a diverse set of materials and technologies to engineer and maintain the levitation system.

鈥淲e aim to establish FLi-MaSS as an innovative solution with implications for inertial sensing for the Department of Defense and other applications,鈥 says Lee. 鈥淭he project may enable a significant move forward in the realization of stable levitation systems and unlocks new possibilities in high-performance inertial sensor technology.鈥

Inertial sensors can measure various parameters of a moving object including velocity, acceleration, orientation and gravitational forces. They鈥檙e commonly used in military applications as well as in smartphones, automobiles and airplanes.

The team鈥檚 vision for future work is to expand the application of their levitation technology beyond the performance of current inertial sensors. Lee and Feng plan to explore its potential in other fields such as precision measurement systems, quantum engineering and advanced communication technologies.

Additionally, they aim to refine the system for improved scalability and integration into commercial and industrial products with low size, weight and power consumption requirements for potential use in sensors.

By advancing the fundamental understanding and practical implementation of levitation systems through FLi-MaSS research, the researchers say they hope to pave the way for new innovations in various high-tech industries.
