Progress Report

This report details the progress made in sensor instrumentation and gel modeling as of March 31, 2011. Key issues addressed include the need for incorporating positive, negative, and ground terminals in sensors, as well as the challenges faced with transistors not functioning with negative voltage sources. Solutions such as using opto-isolators are proposed. The report also discusses advancements in creating physiologically relevant gel models that mimic ventricular shapes through rapid prototyping technologies. Goals for the immediate future include testing new sensors and materials.

Presentation Transcript

  1. Progress Report Joe Lancaster LPPD 3/31/2011

  2. Sensor Instrumentation • Need to incorporate positive, negative and ground terminals. • Transistor doesn’t work with negative voltage source. • Solution? Try opto-isolator.

  3. Physiologically Relevant Gel Model • Bhargav’s tests were in cylindrical cavities • Electrical field lines are spherical; therefore, voltage readings are geometry-dependent.

  4. Physiologically Relevant Gel Models • Ideally, want cavities to resemble the shape of the ventricles as much as possible. • Rapid prototyping machines can produce models from 3D schematics • We can use these models to make gel molds

  5. Rapid Prototyping Product

  6. New Sensor Materials • Silicone catheter sensor had an unfortunate setback • Waiting on new materials to arrive to attempt a new one

  7. Goals for the Immediate Future • Test optoisolator in sensor instrumentation • Look into cost of producing models with rapid prototyping and quality available with UIC’s machine • Resume construction of volume sensor with new materials • Test catheter MKI • Build catheter MKII and test it
