SBIR Phase I: Advanced Composite Sensor System

* 9760097比特 这个小企业创新研究第一阶段将制造一种新的传感器，由复合磁电材料制成的导线。 这项研究建立在以前的工作上的复合层状磁电材料，使用一种新的方法来测量施加的应力。 现有的传感器在测量扩展区域上的作用力时都有局限性。 大多数只对压力有反应，对侧力（滑动、摩擦）不敏感。 其他的则是昂贵的或与矩阵寻址不兼容的，使得大量的传感器阵列变得困难和昂贵。 第一阶段研究项目的目标是设计和制造一种先进的复合材料，其形式为涂有磁电层的小直径（.020”）导线。 传感器元件由与第二导线的交点限定。 低成本和小尺寸将允许制造感测元件的大的密集阵列。 一个主要的软传感器是它测量施加的应力，使其能够测量剪切力或滑动力，并可以配置为密切匹配人手的反应。 复合导线作为传感器有重要的商业应用，但磁电元件本身似乎具有更大的潜在市场。 它可以适用于任何受益于阵列的压力传感应用。 这包括2-D声纳成像，用于医疗和非破坏性测试的超声成像仪，甚至是平板显示器。 ***

*** 9760097 Biter This small Business Innovation Research Phase I will fabricate a new sensor consisting of a composite magnetoelectric material fabricated as a wire. This research builds on previous work on a composite laminar magnetoelectric material that uses a novel method of measuring applied stress. Existing sensors all have limitations for measuring applied forces over an extended area. Most only respond to pressure and are not sensitive to side forces (slip, friction). Others am expensive or incompatible with matrix addressing, making a large array of sensors difficult and expensive. The objectives of this Phase I research project are to design and fabricate an advanced composite material in the form of a small diameter (.020") wire coated with a magnetoclectric layer. A sensor element is defined by the intersection with a second wire. The low cost and small size will allow fabrication of a large dense array of sensing elements. Amajoradvantageoftbissensoristhatitmeasuresappliedstressgivingitthe ability to measure shear or slip forces and can be configured to closely match the response of the human hand. There is a significant commercial application for the composite wire as a sensor but the magnetoelectric element itself appears to have a much larger potential market. It can be adapted to any pressure sensing application that benefits by arrays. This includes 2-D sonar imaging, ultrasonic imagers for medical and non-destructive testing and even a flat panel display. ***
