Acoustic Transducers to use Carbon Nanotubes

Soundwave Medical is developing nanotube array and acoustic nanofilm technologies for use in a wide variety of actuation, sensing, acoustic generation, and sound recording applications.

Shown here is an array of vertical carbon nanotubes on a silicon surface. The use of an array of carbon nanotubes as a charge sensitive capacitor sensor, where a carbon nanotube is responsive to a repelling force, is fundamental to the operation of next generation ultrasound sensors.
