PMTR MOTIVATION & BACKGROUND

Mission Statement: The Mechanical and Biomedical Engineering Departments

at the Rochester Institute of Technology (RIT) have developed a need for a test device capable of measuring the mechanical properties of biologically relevant materials.

Principle Needs: Ability to run simple experiments, demonstrating non-

linear stress-strain responses, creep, and stress relaxation.

PMTR STAKEHOLDERS & NEEDS

PMTR GOALS & VOC

We have split the goals of this project into several categories: Measured Properties Controlled Properties Specimen Accommodation Interface Ease of Use Portability Cost Environmental Health & Safety

All customers have expressed the same/similar needs with varying levels of specification.

PMTR CURRENT TECHNOLOGY Currently, there is no lab

equipment available for educational use in the two Biomaterials courses. Typical tensile testers damage

biomaterials at the clamping points, rendering the test invalid

Previous/Current RIT Projects: Lowell Smoger’s Biaxial Test

Rig P06218 Bausch & Lomb Eye

Membrane Indenter Bill Spath’s EAP Research

PMTR PROPOSED SOLUTIONS

Varying specification requirements of the individual customers led to the need for multiple test rigs.

Proposed test machines: Biomaterials student test machine

Analog display Lower accuracy Control

Research quality test machine Fully automated interface (Matlab or LabView) Closed loop control of loading Higher accuracy Environmental control capabilities Aqueous environment capabilities
