Recently, a research team developed a multi-spectral, super-low-dose photoacoustic microscopy system with a significant improvement in the system sensitivity limit, enabling new biomedical applications and clinical translation in the future.
Published Analog and digital: The best of both worlds in one energy-efficient system
(via sciencedaily.com) We live in an analog world of continuous information flow that is both processed and stored by our brains at the same time, but our devices process information digitally in the form of discrete binary code, breaking the information into little bits (or bites). Researchers have revealed a pioneering technology that combines the potential of continuous analog processing with the precision of digital devices. By seamlessly integrating ultra-thin, two-dimensional semiconductors with ferroelectric materials, the research unveils a novel way to improve energy efficiency and add new functionalities in computing. The new configuration merges traditional digital logic with brain-like analog operations.
