Quantum tunneling pushes the limits of self-powered sensors

Shantanu Chakrabartty's laboratory has been working to create sensors that can run on the least amount of energy. His lab has been so successful at building smaller and more efficient sensors, that they've run into a roadblock ...

Physicists find ways to control gamma radiation

Researchers from Kazan Federal University, Texas A&M University and Institute of Applied Physics (Russian Academy of Sciences) found ways to direct high frequency gamma radiation by means of acoustics.

Monolithic ultrasonic integrated circuits

Ultrasonography based on traditional bulk piezoelectric transducers has been established as an inexpensive and safe medical imaging modality. By borrowing techniques from the microelectronics industry, the performance of ...

Soldiers turn a march into a charge

Engineers at the University of Leeds (UK) are developing a way to capture the kinetic energy produced when soldiers march and use it to power their equipment.
