Ultra-fast random numbers: New generator boosts security and speed

August 20, 2025 Tech Xplore

In computer security, random numbers are crucial values that must be unpredictable—such as secret keys or initialization vectors (IVs)—forming the foundation of security systems. To achieve this, deterministic random bit generators (DRBGs) are used, which […]

Self-powered photodetector achieves 20-fold sensitivity boost using novel device structure

August 18, 2025 Tech Xplore

Silicon semiconductors used in existing photodetectors have low light responsivity, and the two-dimensional semiconductor MoS₂ (molybdenum disulfide) is so thin that doping processes to control its electrical properties are difficult, limiting the realization of high-performance […]

Innovative adhesive film harvests electricity from peeling, enabling battery-free sensing and safety

August 18, 2025 Tech Xplore

A new ultra-thin, transparent film, developed by researchers at UNIST can generate electrical signals solely through mechanical peeling or pressing actions. This technology paves the way for smart sensors that operate without batteries, with potential […]

Technology

Shape-changing antenna enables more versatile sensing and wide-range communication

August 18, 2025 Tech Xplore

MIT researchers have developed a reconfigurable antenna that dynamically adjusts its frequency range by changing its physical shape, making it more versatile for communications and sensing than static antennas.This article was originally published on this […]

Technology

Nuclear waste could be a source of fuel in future reactors

August 18, 2025 Tech Xplore

From electric cars to artificial intelligence (AI) data centers, the technologies people use every day require a growing need for electricity. In theory, nuclear fusion—a process that fuses atoms together, releasing heat to turn generators—could […]
