Marangoni Optofluidic Tweezers (MOT)

There is currently a great deal of interest in using small droplets as containers for chemical reactions. Optical methods for droplet manipulation are attractive because they offer control without an on chip structure; however forces from optical tweezers tend to be in the pN range. Wayne State University researchers have developed a new method...

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...
