BioMedical Engineering: BioMaterials Lab | Trine University

Welcome to Bock 227, the biomaterials lab. In this lab, students learn how to operate and program the tensile tester. The tensile tester contains both manual and pneumatic grips along with heads for tension and compression. Testing has been conducted on synthetic materials including the characterization of metals and polymers and on natural-based materials.

While the tensile tester is in use specific areas in the lab are restricted. These areas are clearly marked with signs. Students are acquainted with the equipment in the Introduction to Biomaterials course and utilized extensively during the senior biomedical engineering design course series.
The torsional tester is also utilized in the introduction to biomaterials course to investigate torsional properties. Students have incorporated the torsion tester as an assessment tool for other design projects.

A portion of the biomaterials lab is designated for open student design space. The lab contains six open tables for student project work and collaboration. In addition, the lab contains three electronic/circuit stations for open work. Each electronic station includes a Keysight Waveform Generator, Keysight Digital Multimeter, protoboards, and two channel Tektronix Digital Oscilloscope.
In addition to the electronic stations, the lab contains a fourth table with a computer for student usage and an additional table with a soldering station.

Along the outside of the lab, there are several storage cabinets to hold supplies, components, and equipment for the lab. Components in the cabinets include a Sonoscape Portable Ultrasound Machine with Linear Array to characterize soft tissue, portable breadboards, Arduino units, NI MyDaq units, spirometers, ECG leads, various measurement sensors and electronic components.

The xurography cutter is used to fabricate two-dimensional shapes from thin plastic materials.
Each two-dimensional shape can be stacked layer by layer to form a three-dimensional construct. Students use the cutter to create microfluidic devices for the BME Research Techniques and BioMEMS courses. BioMEMS is a special topics course in biomedical engineering. The microfluidic devices are used to demonstrate fluid transport principles in microchannels. They can also be adapted to specific biomedical applications, such as diagnostic assays for testing diseases and cell culture platforms for tissue engineering.

The wax printer is used to deposit solid wax onto chromatography paper for the fabrication of paper-based assays.

We hope to see you on campus soon to tour our BioMaterials Lab in person!
