Team Pulse of the Ocean, consisting of Fadel Adib, Reza Ghaffarivardavagh, Sayed Saad Afzal, and Osvy Rodriguez, designed and tested Piezo-Acoustic Backscatter (PAB), the first technology that enables backscatter networking in underwater environments.
Administered by the US Department of Energy and the National Oceanic and Atmospheric Administration (NOAA), the prize competition is designed to spur technology innovation and contribute to the growth of the blue economy.
Part of the American-Made Challenges series, the Ocean Observing Prize encourages integration of marine renewable energy with ocean observation platforms, revolutionizing data collection to understand, map, and monitor the world’s oceans. Competitors were evaluated on the impact of their innovation, end-user market potential, and technical feasibility.
The Batteryless Communication and Navigation for the Subsea IoT
The first underwater technology that enables communication and sensing at near-zero power
PAB is a battery-less sensor that can collect the ocean’s temperature, pressure and pH
PAB nodes harvest energy from acoustic signals using piezoelectric interfaces and communicate by modulating the piezoelectric impedance
Deploying a network of these nodes can enable underwater localization and navigation at minimum power
