Low-Cost Multi-Purpose MEMS/Mechatronics Testing Laboratory for Undergraduate Students

工程机械(56)这个项目正在开发一个低成本、多用途的本科微型机电一体化实验室，基于以学习者为中心的教育原则。该实验室利用廉价的微控制器、桌面无掩模光刻工具和湿工作台，允许学生制造和测试他们自己的微型设备，而不需要进入专门的洁净室。目前正在开展四种不同的实验：(1)演示表面应力和分子吸附的微悬臂梁实验，(2)演示一维热弹性、欧拉-伯努利梁理论和瞬变热分析的热微驱动器实验，(3)演示平板理论和压阻率的压力传感器实验，(3)演示平板理论和压阻率的压力传感器实验；以及(4)演示直流电机的系统识别和闭环控制的机电一体化实验。该实验室的开发是一个多部门总体计划的一部分，该计划旨在创建一个覆盖全校的微纳技术本科课程，不仅满足本科生的需求，也满足其他科学的学生的需求，如生物科学、光学和物理。拟议的实验室体验将培养跨学科技能，并提高激励学生攻读高级工程学位的能力。

Engineering - Mechanical (56)This project is developing a low-cost, multi-purpose undergraduate micro-mechatronics laboratory based on the principles of a learner centered education. The laboratory is utilizing inexpensive micro-controllers, a desktop maskless lithography tool and a wet bench allowing students to fabricate and test their own micro devices, without the need for access to a specialized clean room. Four different experiments are being developed; (1) micro-cantilever experiment demonstrating surface stress and molecular adsorption; (2) thermal micro-actuator experiment demonstrating thermo-elasticity, Euler-Bernoulli beam theory and transient heat analysis in one dimension; (3) pressure sensor experiment demonstrating plate theory and piezo-resistivity; and (4) mechatronics experiment demonstrating system identification and closed loop control of a DC motor.The laboratory development is part of a multi-departmental master plan for creating a college-wide undergraduate curriculum on micro- and nano-technologies addressing the needs not only of undergraduate engineering students but also of students from other sciences, such as bio-sciences, optics, and physics. The proposed laboratory experience is fostering interdisciplinary skills and improving the ability to motivate students to pursue advanced engineering degrees.
