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 a 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.
2. The hydrophone of claim 1 , wherein the magnet is strong enough to keep the ferro-fluid contained within the hydrophone.
3. The hydrophone of claim 1 , further comprising a membrane configured to enclose the ferro-fluid and contain the ferro-fluid within the hydrophone.
4. The hydrophone of claim 1 , wherein the magnet is a permanent magnet.
5. The hydrophone of claim 1 , wherein the magnet is an electro-magnet.
6. The hydrophone of claim 1 , wherein the at least one DNV sensor comprises two or more DNV sensors.
7. The hydrophone of claim 1 , wherein the at least one DNV sensor consists of one DNV sensor.
8. The hydrophone of claim 1 , further comprising a ferro-fluid reservoir configured to contain additional ferro-fluid.
9. The hydrophone of claim 8 , wherein the ferro-fluid reservoir is configured to replenish the ferro-fluid of the hydrophone with at least a portion of the additional ferro-fluid.
