Underwater Internet of Things
MIT's Underwater Sensor Network to Take the Ocean's Pulse Source: MIT Powered Solely by Sound Waves To investigate the vast unexplored areas of the oceans, MIT engineers are building a submerged network of interconnected sensors that send data to the surface. It's an underwater internet of things to monitor temperature changes from climate change, ocean pollution and marine life over long time periods. The MIT team has invented a battery-free sensor, powered by sound waves. The device can monitor the ocean environment at great depths over long periods of time with no battery. The submerged system uses the vibration of piezoelectric materials to generate power and send and receive data. Underwater Communications System This MIT invention appears to be a major breakthrough. Up until now, the difficulty of deploying deep water sensors to study ocean conditions has been greatly limited by their battery life. It's very difficult to change batteries at great
