HK-ELVIS NI-ELVIS Compatible Human Physiology Teaching Kit


SKU: HK-ELVIS Category:


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
