This Small Business Innovative Research (SBIR) Phase I project will explore a fundamentally different approach to digital magnetic sensors. The traditional approach combines a sensor having an analog output with an electronic analog-to-digital converter. In the proposed magnetic field sensor, the analog-to-digital conversion occurs in the physical mechanism of the sensor itself. With this approach only inexpensive digital electronic circuits are needed to complete the sensor system, resulting in a robust, and economically manufacturable design.Being based on standard integrated circuit processing techniques, the new digital magnetometer will be easily mass-produced. The new products will be smaller, cheaper and use less power than existing sensors in a range of applications including: digital compasses, geomaganetic surveying equipment, and vehicle sensors for traffic control and intrusion detection. The very small size of the sensor will also enable new applications using high-density sensor arrays for example in currency and document validation or portable biomedical assay devices.

这个小型企业创新研究 (SBIR) 第一阶段项目将探索一种完全不同的数字磁传感器方法。 传统方法将具有模拟输出的传感器与电子模数转换器结合起来。 在所提出的磁场传感器中，模数转换发生在传感器本身的物理机制中。通过这种方法，只需要廉价的数字电子电路来完成传感器系统，从而实现稳健且经济可制造的设计。基于标准集成电路处理技术，新型数字磁力计将很容易批量生产。 与一系列应用中的现有传感器相比，新产品将更小、更便宜且功耗更低，包括：数字罗盘、地磁测量设备以及用于交通控制和入侵检测的车辆传感器。该传感器的尺寸非常小，也将支持使用高密度传感器阵列的新应用，例如货币和文件验证或便携式生物医学分析设备。
