Planar Microphone Based on Piezoelectric Electrospun Poly(gamma-benzyl-alpha, L-glutamate) Nanofibers

Unmet NeedModern velocity and pressure microphones are highly sensitive instruments. Exposure to extreme heat, pressure, water, or detritus can cause the instruments to fail. Although specialized microphones for use in extreme conditions do exist, they are expensive to manufacture, difficult to produce, and single purpose (i.e. water proof or heat resistant...

Push-Pull Electret Transducer with Controlled Restoring Force for Microphones and Energy Harvesting

Unmet NeedThe traditional push-pull headphones and loudspeakers currently only generate limited amounts of power due to their small size. The limiting factor in the power output for these devices is the amount of movement of the diaphragm and the charge level of the electret. While the power generated by the current push-pull system is sufficient for...

Quantification of Cardiovascular Function by Multi-modality Speckle Tracking

Recently, speckle tracking was introduced as a new method for assessment of myocardial deformation from conventional echocardiographic recordings.1-4 Speckles are natual acoustic makers visible in ultrasound images that can be tracked automatically frame by frame throughout the cardiac cycle. However, due to need of high image quality and the restricted...

Fast Binaural Rendering of Complex Acoustic Scenes

C11644: New 3D Sound Head Tracking SystemNovelty: A headphone based head-tracking system that improves location of sound as the head rotates.Value Proposition: Current head tracking equipment uses expensive electromagnetic based approaches. Commercial gaming headsets are also available, but use infrared tracking so they are only line-of-sight. They...
