How can the CellScale MicroTester be used?

Micro-scale mechanical testing examples

Exploring material testing across various specimens can become complex, especially when illustrating the impact of scaling force or displacement by 100 to 1000 times. Take a look at the examples below or watch our video explaining how the CellScale MicroTester can be used.

Rubber Ball Parallel Plate Compression

A parallel plate compression test of a rubber ball. The ball is 50mm in size and we are applying 200N of force.

Hydrogel Microsphere Parallel Plate Compression

The specimen in this case is only 0.5mm (1/100 the size of the rubber ball). The force required for this test is only 2mN (1/1000 the force applied compared to the rubber ball test).

Popsicle Stick Cantilever Bend

Cantilever bend test on a popsicle stick. The force is 30N and the displacement is 2mm.

Rubber Band Tension Test

A rubber band being tested in tension, with the displacement being 10mm. The amount of force required is 500mN.

Spider Thread Tension Test

The displacement is 1mm and the amount of force required is 0.5mN (1000 times less force required compared to the rubber band test).

Human Hair Bend Test

A similar test on the micro-scale system using a piece of human hair, the displacement being 0.2mm and the peak load being 30mN (about 1/1000000 of the load to bend the popsicle stick).

What are some more applications and examples of the CellScale MicroTester?

In the video below, learn about how we used three different methods to calculate the value for the stiffness of a soft gel material. The formulas we used to calculate stiffness can be found in this white paper (Compression Testing of Soft Materials).
