The iWorx HK-ELVIS Human Physiology Teaching Kit for the National Instruments Educational Laboratory Virtual Instrumentation Suite (NI ELVIS) enables biomedical engineering instructors to teach the theory, design, and prototyping of circuits and signal conditioning circuits as well as 17 experiments and 46 exercises in human physiology.With this novel teaching kit, biomedical engineering instructors can::
safely amplify and digitize human EMG, ECG, EEG, and other biopotentials
control flexible gain and filter settings via NI LabView software to accommodate a wide range of signals and transducer applications
explore biomedical differential amplifier design and probe signal paths
Create experiments and study design of add-on circuits in a protoboard area
compatible with standard molded safety electrode leads and all iWorx transducers
Circuit Design
Students can create experiments and study design of add-on circuits in a protoboard area. Students have the ability to tap into the signal from any channel at any stage and take it to the breadboard area where a custom circuit can condition the signal. The conditioned signal can then be sent to one of the Probe input channels for further evaluation.
Lab Applications
Laboratory exercises that can be performed using the HK-ELVIS kit include the following:
Cardiac Physiology : ECGHeartSounds
Cardiac Physiology : ECGPulse
Cardiac Physiology : ExerciseECGPulse
The HK-ELVIS Teaching Kit includes the iWorx Bioinstrumentation Breadboard, which provides 2 channels of biopotentials, 2 channels of transducer inputs, and a stimulator output.
