An underwater camera without batteries took pictures in the dark ocean

Scientists at the Massachusetts Institute of Technology estimate that 95 per cent of the ocean is currently missing, which means that underwater depths are even less studied than Mars or Luna, and that engineers have created a camera to solve this problem that does not need external wire or batteries for power.

The difficulty in studying the underwater world is that they require the research apparatus to be linked to the surface of the vessel or the permanent replacement of batteries, which is explained by the authors of the new development, resulting in a high cost of underwater expeditions.

Engineers have introduced a wireless wireless underwater chamber, which is about 100,000 times more energy-efficient than analogs; the device takes colour photographs even in the dark under water and transmits images over the wireless network via water.

The Autonomous Camera operates from sound. It converts the mechanical energy of sound waves passing through water into the electrical energy that feeds it with image processing and communication equipment. After capture and coding of the images, the Camera also uses sound waves to transmit data to a receiver that reconstructs the image.

Since it does not need a power source, the camera can operate autonomously for several weeks, says scientists. A new device can explore remote parts of the ocean and search for previously unknown species of animals and plants, and can also be used to survey ocean pollution or to monitor the health and growth of fish grown on aquaculture farms.
