3D Soundscaping

Researchers at WSU have developed a 3D Soundscaping technology that enables one to take sound measurements to a new level by locating sound sources, visualize their resultant sound pressure fields in 3D space. In traditional sound sensing applications, sound is measured using microphones and sound pressure levels and spectra are measured at survey locations....

In-Cylinder Cycle-by-Cycle NOx Measuring Technique in Spark Ignited Engines

Currently, there is no technique that determines the quantity of NOx present at the end of the combustion cycle in spark ignited engines. Existing technologies for measuring NOx in spark ignited engines are limited to slow response sensors placed in the engine exhaust. Wayne State University researchers have developed a novel technique to determine...

Vibration Energy Harvesting Device Based on Air-Spaced Piezoelectric Cantilevers

WSU researchers have designed an energy harvesting device using an air-space piezoelectric cantilever instead of the piezoelectric bimorph. Current vibration energy harvesting devices typically employ piezoelectric bimorph or a bimorph with a shim in the middle. The use of the air-space cantilevers produces numerous advantages compared to conventional...
