Development, Manufacturing, and Application of Photoacoustic Test Phantom

Christie L.B., Schneider P.J., Heidrich J.R., Oh K.W., University at Buffalo, US

Photoacoustic (PA) research is an up and coming field that is being applied to the medical space. PA combines the use of both optics and acoustics to create a final outputted signal (Figure 1). The [...]

Computational Modeling of a Wearable Device with Feedback to Advance the Healing of Chronic Skin Ulcers

Heidrich J., Oh K.W., University at Buffalo, US

This paper discusses how COMSOL Multiphysics modeling software allows for design ideas to be validated through computer simulation. The simulations generated show the Organic Electrochemical Field Effect Transistor (OECT) with a Poly(imide) (PI) polymer microfluidic [...]

Automated Classification of Defected Images by Means of Machine Learning for Improved Analysis of Vehicle Undercarriages

Giegerich W.V., Stone A., Forte III L., Schneider P.J., Oh K.W., University at Buffalo, US

This research focuses on the development of a vehicle undercarriage image quality machine learning model. The model returns the quality of the image across several categories which are used for classifying image defects. Through analysis [...]

Enhanced Corrosion Detection By Means of Multispectral Imaging and Postprocessing Techniques

Giegerich W.V., Fedorishin D.C., Forte III L., Christie L., Schneider P.J., Oh K.W., University at Buffalo, US

This research focuses on the implementation of an enhanced corrosion detection algorithm using multispectral imaging techniques and post-processing image filters. Utilizing various combinations of light filters with image enhancement software, we are able to increase [...]
