The romantic imagination and courage to explore unknown fields are important sources driving human progress. People perceive and understand the colorful world through vision, smell, hearing, touch, and taste. With the advancement of sensor technology, traditional human perception methods have been greatly expanded, achieving a qualitative to quantitative deepening of information perception regarding temperature, pressure, … Read more
Western military powers rely on advanced and precise weaponry to deter and defeat asymmetric and near-peer adversaries. For better effectiveness, these weapons should match accurate information about the targets, such as location and status. For time-sensitive targets, this information needs to be provided quickly, or the target may change. The process defined as the “Sensor … Read more
Compared to traditional sensors, fiber optic sensors are non-electrical, resistant to electromagnetic interference, electrically insulated, corrosion-resistant, intrinsically safe, capable of multi-parameter measurement (temperature, stress, vibration, displacement, rotation, electromagnetic fields, chemical quantities, and biological quantities), highly sensitive, lightweight, compact, and can be embedded in objects. The fiber optic sensing network is a sensing network composed of … Read more
Authors: Wang Jing, Chen Jianfeng, Zhang Lijie, Huang Jianguo, Source: Streams of Ocean Life 1. Introduction Underwater wireless sensor networks (UWSNs) utilize aircraft, submarines, or surface vessels to randomly deploy a large number of inexpensive miniature sensor nodes (ranging from hundreds to thousands) into the water of interest. These nodes form a multi-hop, self-organizing network … Read more
