Abstract:
|
Our objective is to determine the most appropriate statistical method to analyze data collected in biomedical engineering research that involved the shape change characteristics of ionic hydrogel under different electrical stimuli. The hydrogel samples were prepared by dissolving PVA and PAA in deionized water at 4% and mixed together at a 1:1 ratio. Samples were dehydrated then immersed in DI water. Swelling was then recorded in relation to time and electric field which was gradually increased. The rectangular shape change due to the electric field was measured using an optical microscope. The experiment was conducted with the intent of observing stimuli-responsive swelling behavior of the hydrogel which is being investigated for the enhancement of cell function and cell dispersion.
