Self-powered, Acoustic Impedance-matched Transducer

Unmet NeedAcoustic energy (i.e., sound energy) is an energy disturbance that can pass through materials in the form of waves.1. Examples of sound energy can be speech, music, or environmental noise. The wave vibrations from sound energy contain a wealth of information about their source and surroundings. For example, body sounds can provide health and...

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...
