"The successful landing of any flying vehicle relies on minimizing the velocity as it approaches the surface before impact and dissipating energy quickly after the impact," explained Nak-seung Patrick Hyun, a former Harvard postdoctoral fellow and now an assistant professor at Purdue University's School of Electrical and Computer Engineering. "Even with the tiny wing flaps of RoboBee, the ground effect is non-negligible when flying close to the surface, and things can get worse after the impact as it bounces and tumbles." Hyun led the RoboBee's landing tests on both solid surfaces and a leaf, just like a real insect.

Mark Lundstrom, Purdue's chief semiconductor officer, answers zoning concerns for a $3.87B facility - including from colleagues - why SK hynix picked WL over LEAP and a case for a silicon heartland.

"Right now, a soil moisture sensor, you'd have about 1 of those per 100 acres. In the future, you might have hundreds, or even more, per acre," said David Love, the Nick Trbovich professor of electrical and computer engineering.

"Our hope for quantum computation is that it will aid chemists, materials scientists and engineers working on the design and manufacturing of new materials that are so important to our daily lives," said Michael Manfra, scientific director of Microsoft Quantum Lab West Lafayette, professor of electrical and computer engineering, Bill and Dee O'Brien Distinguished Professor of Physics and Astronomy, and professor of materials engineering at Purdue.

"Today's atomic clocks enable GPS systems with a positional accuracy of a few meters. With an optical atomic clock, you may achieve a precision of just a few centimeters. This improves the autonomy of vehicles, and all electronic systems based on positioning," said Prof. Minghao Qi from Purdue University

Purdue University engineers and the Indiana Department of Transportation are working to make it possible for electric vehicles, big and small, to wirelessly charge while driving on highways. Construction is in progress on a quarter-mile test bed on U.S. Highway 231/U.S. Highway 52 in West Lafayette that the team will use for testing.

"Purdue University researchers are pioneering a path forward by harnessing solar power and IoT technology for smarter irrigation," said Woongkul Matt Lee, Assistant Professor of Electrical and Computer Engineering at Purdue. "This innovation empowers farmers to control irrigation precisely, reduce energy costs, and embrace sustainable practices, marking a pivotal step in addressing modern agricultural challenges."

Tongcang Li, a professor of physics and electrical and computer engineering, leads a team that has developed the BNNTs with optically active spin qubits. "BNNT spin qubits are more sensitive to detecting off-axis magnetic fields than a diamond nitrogen-vacancy center, which is primarily sensitive to fields that are parallel to its axis, but not perpendicular," Li said. "BNNTs also are more cost-effective and offer more resilience than brittle diamond tips."

At Purdue's Video and Image Processing Laboratory, Prof. Ed Delp and a team of graduate students use powerful computers to help detect which images are fake and which are real.

"Our scheme opens a large opportunity for the adoption of deep learning-based anti-counterfeit methods in the semiconductor industry," said Alexander Kildishev, professor at Purdue University.
