Thermal management is important for medical ultrasound probes to maintain optimal performance, reliability, and lifetime of the devices, as well as to avoid heat-induced damage to the patients’ tissue. This paper presents heat transfer simulations of the scan head of a trans-esophageal echocardiogra...

Fiber orientation in film gated injection-molded rectangular plates was characterized using micro computed tomography. Polyamide 12 materials with 15, 30, and 50 wt% glass fibers were used in this study. For all three materials, the typical core-shell layer structure of fiber orientation was observe...

Two key issues in the manufacturing of microfluidic devices are to obtain low surface roughness, i.e. in the range of nanometers (to facilitate optical detection and controlled flow through microfluidic networks), and to achieve robust bonding. Here we report that a chemical polishing step, used for...
