AbstractA comprehensive plan of work for designing and operating the next generation of self-powered magnetic sensors is presented. Using ideas and methods from nonlinear dynamics research in Engineering, Mathematics, and Physics, proof of concept is presented showing that higher sensitivity, lower power consumption, and reduced costs, can all be achieved through an integrative approach that combines a novel Intelligent Magnetic Sensor Network Architecture with a new sensing technique. The network architecture is intelligent in the sense that the nonlinear characteristic of each sensor can be exploited to make the network generate its own self-biasing signals, thus reducing power consumption and manufacturing costs. The goals of the proposed project are to advance knowledge and understanding of the field of sensors and student participation, especially minority, in research activities. The project has a strong potential to directly impact science and industry in many areas where magnetic sensor devices are commonly used. Examples include: biomedical tracking of magnetic particles, e.g., MRI machines, which are commonly used for diagnosing multiple sclerosis, brain tumors, spinal infections, etc.; geological equipment, e.g., NASA explorers; homeland defense, e.g., detection of mines and explosives.

摘要提出了设计和操作下一代自供电磁传感器的全面工作计划。利用工程、数学和物理领域非线性动力学研究的思想和方法，提出了概念验证，表明通过将新型智能磁传感器网络架构与新传感技术相结合的综合方法，可以实现更高的灵敏度、更低的功耗和更低的成本。 该网络架构是智能的，因为可以利用每个传感器的非线性特性使网络产生自己的自偏置信号，从而降低功耗和制造成本。拟议项目的目标是增进对传感器领域的知识和理解，以及学生（尤其是少数群体）参与研究活动。该项目具有直接影响磁传感器设备常用领域的科学和工业的巨大潜力。例子包括：磁性粒子的生物医学追踪，例如MRI机器，通常用于诊断多发性硬化症、脑肿瘤、脊柱感染等；地质设备，例如 NASA 探险家；国土防御，例如地雷和爆炸物的探测。
