First Claim
Patent Images
1. A hydrophone comprising:
- a ferro-fluid configured to deform when contacted by sound waves;
a magnet configured to activate the ferro-fluid;
at least one diamond nitrogen vacancy (DNV) sensor configured to detect the magnetic field of the ferro-fluid and to detect movement of the ferro-fluid; and
an electronic processor configured to translate movement of the ferro-fluid into acoustic data associated with the sound waves.
