Designing materials for next-generation propulsion systems

The ability to reliably order groceries or takeout, have rapid package delivery, check the weather forecast, or follow GPS tracking is all a part of the US's ever-growing satellite and space economy. The continued growth of this economy relies on advancements in propulsion technologies. One such breakthrough is the “Rotating Detonation Engine" (RDE). The RDE offers the ability to deliver satellites to precise orbits in outer space with greater robustness and reduced fuel consumption and emissions than with current conventional engines.

Brain organoids could unlock energy-efficient AI

Our brains are masters of efficiency.

“Biology is very energy optimized,” says Yevgeny Berdichevsky, an associate professor of bioengineering and electrical and computer engineering at Lehigh University. “The amount of energy the brain uses at any given time is roughly equal to a light bulb in terms of wattage. Replicating those computations in hardware would demand orders of magnitude more power.” 

Zheng pioneers faster, eco-friendly underwater communications technology

ECE Professor Rosa Zheng and her team have unveiled a groundbreaking underwater acoustic communication prototype that harnesses high-frequency MIMO technology and turbo equalization to dramatically boost transmission speed and reliability. Unlike traditional sonar-based methods, which are slow, echo-prone, and disruptive to marine life, Zheng’s system transmits weaker, higher-frequency signals that fall outside the range of marine mammal hearing.
