AB  -       Lessons Learned from the Application of Virtual Instruments and   Portable Hardware to Electrode-Based Biomedical Laboratory ExercisesAbstractPortable data acquisition hardware and virtual instruments offer students the flexibility tocomplete laboratory assignments at home, alleviating traffic in conventional laboratories while atthe same time offering an instructional mode more consistent with the students’ connectedlifestyles. To that end, the authors used support from the National Science Foundation CCLI(TUES) program to develop a hardware platform referred to as a Rapid Analysis and SignalConditioning Laboratory (RASCL) unit. This tool offers a power supply, a large-areabreadboard, an analog function generator, two electrically-isolated input channels, and acollection of connectors for input/output signals. Analog and digital signals from the circuitry onthis board are sent via a ribbon cable to a National Instruments (NI) myDAQ® personal dataacquisition unit, which then connects through a USB port to a computer running the NILabVIEW® software. Students therefore have access to a collection of virtual instrumentscoupled with the hardware necessary to build and test circuitry at home.This paper focuses on the improved design of the version 4.0 RASCL board with respect to theusability of the electrically isolated channels and the quality of the resulting signals. The designeffectiveness was assessed within the context of a Fall 2011 course: ECE 772 – BiomedicalInstrumentation. These laboratory exercises addressed variants of electrode-based biomedicalcircuitry, including electrocardiographs, electromyographs, and electro-oculographs, where theuse of isolated channels added a necessary safety layer. Each student worked with their ownRASCL unit and built the base circuitry for all three exercises around a traditionalinstrumentation-amplifier-based core. PSpice simulations corroborated anticipated circuitbehavior. Students assessed the frequency content of each of the respective signals prior todesigning and building the appropriate filter circuitry. Laboratory report assessments, coupledwith end-of-semester surveys, indicated that (a) learning objectives were met, (b) studentexperiences were positive, and (c) the resources provided by the portable toolset were sensiblealternatives to benchtop hardware that would normally be employed in those exercises.
